MultiCharts: Trading Software for Automated Trading and Backtesting

Zheka

Why not use:
- pmm_set_global_named..
- pmm_set_my_named_
- pmm_set_strategy_named_

...and avoid using GVs altogether?

Zheka

'Compressing' here means 'compressing to an internal database format for storage'.

Why not just open QuoteManager and have a look at the database data for your symbol?

Zheka

There are no in-built tools for that, but you can use the min possible position size when the system is to be switched off. And you'll have to maintain your closed-trade equity yourself. This will allow you to backtest your logic, but will unfortunately not work with MC/PT in live trading. I once ha...

Zheka

Is there a problem using any of CQG, Rithmic or TT FCMs ?

Zheka

Are you doing genetic or brute-force optimization?

Zheka

You only corrected RSI, need to do the same in all similar cases.
Accessing data3 is no different than data2.

Zheka

RSI(Close,Rsi_Length) data(2) <RSI_Up

Zheka

What does that suppose to mean? RSI_Up data(2) or dir=-1 data(2) If you want to call a function on data2, then the syntax is f() data(2) (and it will take input parameters from data2 -so no need to pass Close2). If you want to use a variable, changing its value only on each bar of data2, then you de...

Zheka

As the first step, try changing function calls from:

Code: Select all

MA100Value = Average( Close2, MA100Length )data2 ;

to:

Code: Select all

MA100Value = Average( Close, MA100Length) data(2) ;

Zheka

Did you try looking in PLEditor?
It has the Dictionary of all keywords and in-built functions catalogued by theme, with explanations and examples..

Zheka

These are also available programmatically via MaxPosProfit() , MacContractProfit(), OpenEntryProfit() and OpenEntryProfitPerContract ().

Zheka

Look at the List of trades in the Performance Report: each trade has a Run-up and a Drawdown.

That's what you are looking for. Export the list to Excel and analyze as you wish.

A Performance report also has separate tabs with visual analysis of these stats.

Zheka

It probably has to do with wrong parameter type declaration in DefineDLL: passing an array(of doubles) requires a *pointer-to-double*, not just Double. Try declaring it as LPDouble, and try finding an EasyLanguage Extention SDK referenced here: https://www.multicharts.com/trading-software/index.php/...

Zheka

It is clearer

You have access to all the trades, so calculate 'Sharp ratio' based on trades, not on 'calendar periods'.
It will be the more adequate measure for your purposes.

Zheka

Hi joebone,

it is not really clear what you want to achieve...and why skipping certain periods - either in a 'hard-coded' way or by defining 'high vol' periods dynamically - hurts your ability to optimize by a metric you want?

Zheka

Pacing violations should go away as soon as MC plug-in implements the latest IB API.

Zheka

This will not work reliably all the time. I could not make 'data reloading' work well in live trading..

Zheka

An indicator will not really help when you backfill for 50+ symbols in Portfolio Trader, especially when auto trading.

Zheka

Problem : - if some data is missed during a backfill ( problem with broker API, no quotes, bars filtered out, etc), a user has no way of knowing. Suggestion: Upon backfill, MC/ PortfolioTrader should transparently "Alert" the user in case some data are missing. These alerts should show a user the p...

Zheka

Problem: When setting "Bars back" in an instrument settings, MC will make requests to the broker API until it obtains X bars, even if bars for certain periods are skipped. E.g. requesting 24 60min bars (back) should cover a period of 1 day (with a 24 hr session) But currently, if some bars are misse...

Zheka

It often happens that due to a glitch in PT-broker(IB) connection, there are gaps in historical data. However, Reload functionality currently only works in MC - which makes it a hassle reloading data for a big number of symbols. Please implement Reload functionality in Portfolio Trader. https://www....

Zheka

It would help immensely to quickly judge performance of a Portfolio, if a user could not only see the Total Portfolio Equity, but also its components. There could be a 2-level dialogue window or - better- a table with toggles, allowing one select either entire strategies or entire instruments or cho...

Zheka

Yes.
It is worth reviewing it from time to time and casting your ballot/filing issues - if you want to change things.

And it will improve your understanding of how MC/PT work (or do not work) immensely.

Zheka

Zheka

You do have to export input parameters and key metrics to a .csv file during optimization. Then use EL Collections (search in User Contributed studies on this forum) in your other script to read and map the table in the file, then apply your logic for selecting a specific line and then populate the ...

It is doable in backtesting buy setting the trade size to 1, but would be inefficient (and with any exchange-traded product with some decent min.lot size - impossible) to implement in live trading with PT. Unless of course you implement all systems as functions and calculate/maintain all needed stat...

Zheka

MC does not store real-time ticks (from which it constructs 1-min bars) to QM database by default. You need to "Flush" them to the database manually to be able to observe and compare the timestamps. 1-min bars up to the last full minute come from historical IB servers (and saved), the current "not-y...

Zheka

First, you should compare apples to apples: you Live chart is based on Trade (is it mid-point for Oanda?), while you backtest is based on Bid. Second, with this kind of spreads (9-10pips!?? really?): - your backtest is "unrealistically good" by design - your buy orders are executed at much better pr...

Zheka

It loads the data from the local database upon each backtest, currently there is no cache of this data. That's exactly the bug - introduced in MC12 and absent in MC11, and as such IMHO should not be just "fixed in some future release", with undefined ETA. That was the reason for this thread, pls re...

Zheka

sorry, it is indeed in another pair...then disregards my comment..

Zheka

Zheka

You could achieve this by:
1) setting up the symbol list in Portfolio Trader
2) adding a small block of code (or a separate signal) to write to a file the performance metrics you need

Zheka

Well, that's as close as you can get it...And it is indeed possible that some trades were busted/cleaned out and corrections made after the day close. No one is to blame, that's just "real-life". The best you can do is to "Flush cached data to database" before closing MC. So, MC should/will not be r...

Zheka

Anna,

correct me if I am wrong, but when PT "Downloads missing historical data" on the FIRST backtest, there is no need for another download - there is no "missing" data.
This initially collected data is in cache and used by all subsequent backtests.

What's the bug that was corrected?

Zheka

Anna,

this is a bug that was introduced in MC12.

Before any enhancements are made, let's correct the bug in the nearest MC12 release.
It does make the process of testing in PT inconveniently slow .

Zheka

Yes, experiment..

Zheka

OK, then it makes sense. 15-60sec bars would be a more robust solution then IOG. All logic besides exit split behind a barstatus(2)=1 check. Also, if you do not employ a portfolio-level MM logic in real-time, you might be better off trading from MC rather than PT - since MC uses 1 core per chart and...

Zheka

I made it less granular, not more. You made it more granular compared to a "decision" time frame. With our 1-minute strategy, fine, but with our 1-hour strategy this would be a drastic change that we'd need to backtest. If your strategy logic relies on a smaller timeframe - then it means it is not ...

Zheka

You don't need a more granular Data1 at all - unless you are really micro-managing entries/exits with an "execution algo". If you need to trade intrabar, then a stop/limit order submitted at bar end will work just fine. Getting to a more granular time-frame will not solve the problem of "delays" - i...

Zheka

But no big deal, I'll increase the interval. Maybe 15 seconds.

You really insist on paying your dues.

Zheka

For both I use 1-sec Data1 bars, which isn't important to their success, so should I not

The question should be just the opposite: do you really, REALLY need it?
You whole production set-up should be scrutinized from this perspective, and optimized for robustness.

Zheka

@pcrespo,
What's the bar interval for your primary trading logic and what would be your typical trade length?

Zheka

What's the bar interval for your primary trading logic and what would be your typical trade length?

Zheka

@pcrespo, I feel you are overdoing it and "observation" influences the results. I/O operations (like printing to a file) are relatively slow, and you are printing at each tick and bar close! My advice: - sync clock once in 15 minutes, not seconds - use 15-60sec bars - find time differences via datet...

Henry, I knew there are probably "some well-reasoned calculations" even as I submitted the PM. Whatever they are, they just do not make sense. Or are not applicable.

Zheka

Anna, You misunderstood the issue. PT downloaded missing historical data even before MC12. The problem is that now, after loading data for the FIRST backtest (either from the database or also filling in some missing data), MC12 loads them from the database ANEW/AGAIN for all subsequent backtests (on...

Zheka

It is misleading to judge the quality of connection by ping (which uses a different protocol for measurement).

One can observe real-time TCP connection latencies under load just by opening a Resource Monitor in a Task Manager and looking under Network/TCP connections.

Zheka

Set data to Trades and 1-tick and see how frequently MC plots/updates the data to ensure it actually works. My suggestion re 1-tick resolution was to VERIFY (rather than ensure) that it works. These 5-sec bars will be the "ticks" (actually, they are recorded by MC as 4-ticks in the database - O-H-L...

Zheka

is the the "Use 5 seconds bars as ticks" you are talking about Yes, this is the one. 5-sec bars come with 250-300ms delay in real-time from IB's historical data server, cleaned, so you are guaranteed to have historical=real-time. All with minor processing load compared to getting all of the ticks i...

Zheka

THE solution to this issue is to use IB's True Real-Time 5-sec bars, instead of ticks.
For that, switch to "use 5-sec bars as ticks" in IB's plug-in(datasource) settings; you might need to use Trades as a datastream (rather than Bid-Ask).
Please search forum for related/my posts for details.

Zheka

I have experienced the same unnecessary reload of all of the instrument data in PT when backtesting.

@Anna,
did you manage to replicate it on your end?

Zheka

@Zheka - quad core was the lowest available from OVH. I'll shop around for a server with faster (and possibly fewer) cores. I've read you have a 4xCPU server. Of course, if it's a single 4-core Xeon E3 - then there is no real need. Still, you will do better with a i7-7700K, which is also a quad-cor...

Zheka

Yes, CPU seems to be "good enough", though you would be better off with 1x i7-7700K (or 6700K).. Why do you need a 4-CPU set-up on a production machine? TCP Optimizer will mostly cover it, just read the docs/search the web to understand what specific settings mean and how "networking" works. You can...

Zheka

@Zheka - yeah, switching to IB data was going to be my last resort, which seems to be where I'm headed. I just ran a speed test to a server in Dallas. I don't know how indicative it is, but I got 116 MB/s (927 Mb/s) Down and 26 MB/s Up. Hmm:-) I was talking about latency (and tuning NIC/TCP stack i...

Zheka

Several things came to mind: - "Pings" are not at all representative of real latency under load. - your network card/TCP stack settings and CPU processing power will somewhat influence your overall "trading system" latency, especially in times of heavy trading/tick count across several instruments -...

Zheka

To add:
with "Request Historical ticks directly from API", MC gets Bid prices=Ask.
w/o "Request H...", MC gets, but does not save any tick data to the database (as reported above)

Zheka

1) IB CFD historical data would not load, motivating that "Data are not subscribed" and that it would start getting Delayed data after the delay period. - I do have all the IB permissions for CFDs - that was not a problem with MC11 Thank you for your answers, Henry. I tried to get you the logs, but...

Zheka

Henry,

could "Flush Cashed Data to Database" be also integrated under File->..... into the main program, so you don't always have to open the Quotemanager?

Fully agree.
There is hardly a reason for placing it in QM if the data to be "flushed to database" are collected in the main MC program.

Zheka

Started using MC 12 with IB, stumbled upon several issues: 1) IB CFD historical data would not load, motivating that "Data are not subscribed" and that it would start getting Delayed data after the delay period. - I do have all the IB permissions for CFDs - that was not a problem with MC11 2) How do...

Zheka

Technically, a broker would allow opening a new position if you have sufficient equity - at that moment - to cover the margin. To only base your sizing decisions on closed equity, you need to explicitly code this around. You can also play with PortfolioTrader Portfolio Settings (Exposure, Required C...

Zheka

Thank you!

Zheka

WOW!
I did not know it is possible to reference indicator plots as inputs.
Is there somewhere a more general "use case" description with syntax, all the limitations and nuances?

Zheka

A simple solution to this set of issues is to use IB's "True RT 5-sec bars" feed , covering all ticks in these 5 seconds. For the cost of 250-300ms delay, you get a "cleaned" 5-sec bar (o-h-l-c) from IB's Historical data servers. If you do not use tick bars, and the trading bar interval is longer th...

Zheka

To add to the issues:

It seems to be currently not possible to have a variable size of a stop/trailing stop via standard MC order commands.

(which btw is not at all obvious for a user!), making such reports highly misleading and not practically usable. One would need to export the results to Excel and work w...

Zheka

This might be connected with Required Capital assumptions (see top-right part in Portfolio settings)/Margin per contract settings.

Try to debug with 1 strategy, 2 strategies..

Zheka

How did you set-up your portfolio?
Is it one "signal" (=strategy logic) applied to many instruments or many (same) "strategies" each applied to one instrument?

Zheka

Why guess? As TJ suggested, launch a Task manager and from there, if necessary, a Performance Monitor. Observe if, under your full set-up, CPU load, RAM consumption and SSD usage are at their maximum and are a bottleneck. Then close 1/4 of workspaces and observe again...repeat until you get a good f...

Zheka

This will allow separating position sizing algos/signals from the core signal logic also in MC, will simplify code, etc. Yes, it is possible to vary position size in PT MM signals, but this does not cover quite a number of use cases. E.g. when dynamic sizing algos are different by strategy/instrumen...

Zheka

You don't have a problem.

The difference between the arrows and the fills is because of Heikin-Ashi bars; HA Open is not determined by time.

Zheka

What's wrong with what you described? An arrow placed incorrectly or the real trade?

What's the timestamp of the first tick (=open) of this bar? By default, MC opens a bar only when the first tick of it appears.

A screenshot would help.

Zheka

My question was about the time, not price. How much time passes - on average - since bar open? Is there a pattern?

Zheka

Does the order get executed on time, i.e. as soon as the next bar opens?

Zheka

But does it work as it should in backtesting?

Zheka

Array_Sort loops through the array AND moves values in memory. Much more expensive than just looping and saving.

Zheka

There is no way.
Why do you want to avoid looping?

Zheka

Alex,

But in the screenshot you attached the date is *pinned*, fixed.....No wonder you do not get trades.

Zheka

With MC, it will cancel and resubmit the same order with the closing of a bar.

AFAIK, MC cancels/resubmits a limit order, only if its price changed.
Write an email to Support, if it does not.

I was able to see how OANDA compared. They don;t.

In what sense?

Zheka

In forex limits are filled at touch. Futures you have to expect to go through the price by a tick In a free 'market" (ECN in case of IB or exchange in case of futures) if there is somebody on the other side - you will be filled. So, it all comes down to depth/liquidity at the time. Now, practically...

IB Gateway is a small gateway app from IB to connect via API. I am not clear on your item #2. Is this step the one that makes it stable? No, it is stable by design (and lack of GUI).

Pity. What's the recommended way then to trade such non-native (to the exchange) symbols? Monitor DST and manually adjust as you go?
How to correctly do the backtesting?

In this case each instrument will be calculated in his own base currency (price*big point value).

You mean performance statistics will be calculated in each instrument's base currency, right?

What will happen to all margin-related calculations at the portfolio level?

Portfolio money management functions (e.g. pmms_strategy_deny_entry() ) not only disallow sending orders to the broker, but also cancel them for a strategy altogether, as if they did not happen - which affects strategy statistics. But to implement "Equity curve trading" (and in some other cases) suc...

Will anybody at MC please answer?

Hi, Anna, I observed this behavior when "live" paper trading in Portfolio Trader - with neither QM, nor core MC running. Just IB Gateway and PT. Please check this on your end. I verified that core MC constructs RT bars from midpoints correctly. But I have no way to verify that this is similarly so i...

It would help immensely to quickly judge performance of a Portfolio, if a user could not only see the Total Portfolio Equity, but also its components. There could be a 2-level dialogue window or - better- a table with toggles, allowing one select either entire strategies or entire instruments or cho...

Zheka

When trading multiple strategies on the same instrument via PT, aggregating orders and sending only the "net" amount to the broker would reduce transaction costs.

It would be great to have Order and Position Tracker in PT filterable also by Strategy Name - as defined in Feature Request #2346 https://www.multicharts.com/pm/public/m ... es/MC-2346

https://www.multicharts.com/pm/public/m ... es/MC-2347

Zheka

At the moment, the Strategy Name column in Orders and Position Tracker in PT just repeats the signal names used in Strategies. A list of them! This is useless if one runs strategies with similar signals but with different parameters. Expected Strategy Names are how they are named in the Portfolio tr...

Midpoint data is requested for Forex trades from IB

.
I know, Anna. I was the one who requested this feature to be implemented.

But Walter referenced different MC behavior under different IB API versions - and this made me curious.

Zheka

Sorry, just read the previous thread on the subject.

@Angelina,
When will a global 'toggle' solution be available (rather than a cumbersome registry edit)?

Zheka

Just got a message that

"Currency conversion is not supported for USD.MXN@IdealPro.
Please set Base currency to None"

Is that because currency conversion is handled with rates from MCFXPrivate which doesn't have this pair?

Zheka

I have been running PT with FX instruments set for using mid-point True RT bars from IB (i.e. Trades; Use 5-sec bars as Ticks). Observing IB Gateway logs, I could see that indeed the 5-sec bars are coming to the api client. However, live tick Bid and Ask are subscribed to by MC as well. This makes m...

Is there a Registry key to enable showing milliseconds in the Date/Time fields in OPT and Logs in Portfolio Trader?

OPT in MC shows milliseconds, but not in PT.

Zheka

Re 1): Interesting! What does IB API provide as Trades for FX?

Because IB API states that "TRADES" Tick Type is not available for FX.

Dear MC, I need to implement a portfolio of multiple strategies on multiple instruments, choosing signals dynamically from a large pool (>50) of variations per strategy. Implementing the above in PT is not difficult and is acceptably quick to backtest, but it lags in RT. MC offloads calculations of ...

Zheka

Henry, it is of course not necessary to "constantly" request historical data. Making a request just 1 time, 50-200ms before 1-min bar "closure" would be enough to accurately capture O and H / L, saving both ticks AND 1min bars (both are historical except the last 200-300ms) straight into QM database...

Zheka

Starting from recently released IB API v973.04, it becomes possible to request historical tick data. https://interactivebrokers.github.io/tws-api/historical_time_and_sales.html#gsc.tab=0 This would potentially allow building and saving a 1 min bar almost in RT (building it from the regularly request...

Zheka

Thank you, Josh!

I somehow never explored the Symbol_* functionality....It actually did the trick!

Nevertheless, I think the current implementation of MaxBarsback is to be corrected.

Zheka

I have tested it, and it works as it should!

Thanks!

Zheka

There is a *nuance* in MC which makes life unnecessarily harder. Say, you have 1 min bars as Data1 and need it 200-300 bars ago - for an indicator. But you also have Weekly bars as Data2 - for gauging a 20-Week ATR. Then, you might not have enough data to backtest, since a Maxbarsback setting of 250...

Zheka

+1!
This would be a great time-saver!

Zheka

Try connecting via IB Gateway instead of a bulky TWS.
Added benefit is IBG does not try to log off once a day and can run for months.

Zheka

We will seek for possible improvements in one of the future versions. Pleeease! This will make this functionality usable. Plot ticks either from 1 second snapshots or 5 second snapshots from server Historical bar is split into multiple ticks. A tick is generated by MultiCharts on each change of O-H...

I have noticed a setting in IB's Profile under Data Sources called "Download historical data\ Don't request data for empty periods". Checking it on/off did not result in an attempt to re-download missing data. Would be really great to make this checkmark do what it is seemingly supposed to! (if redo...

Zheka

The problem is, most of us do not need to edit data very often. A stage of "You do not know that you do not know" I thought so as well until: 1) I found - by chance - several gaps in the data (from 2 days to 2 weeks) that were nearly impossible to identify visually (and so found out that MC does no...

Zheka

Since datafeeds are not perfect, one needs to clean erroneous data or know of /fill-in the gaps. Right now, a trader has to change each and every bad tick/value manually. Would be very helpful if MC could automate these tasks. 1) Have a tool that would scan the symbol's data in a database and report...

Realtime bars are updated once in 5 seconds with a single Close value. This update does not work as actual correction, bar’s OHL values will not be changed, only the close will be updated. Realtime bars can be different from historical bars, that is expected behavior. IB streams 5-sec True RT bars ...

Zheka

It is a real pain and wastes a lot of time when you discover that certain data had not been downloaded by MC (from IB) (for some reason) and all your work should be thrown away. I assumed that MC scans for gaps in the data and tries to download those missing but discovered this not to be the case. A...

Dear MC,

Would greatly appreciate answers to my questions above.

Also, would be great to have this feature working for CFDs. Trade field is just empty at the moment.

Thank you.

Normal correlations among system results are not at all useful in creating a diversified portfolio, i.e. finding complementary equity streams to reduce drawdowns and maximise Profit/DD ratio. A practical and correct approach is to calculate correlations of closed-trade equity in a drawdown ("under w...

Zheka

Current "Rolling Period" analysis is not really "rolling" (it is anchored!) and is not useful for understanding strategy performance (needed to monitor results subsequently in RT). A user should be able to specify a number of "periods" to roll (e.g. 3-month rolling window, 4-weeks, etc). Key metrics...

It would be a very useful feature to be able to generate the whole "Performance report" (or at least Summary, Trade statistics as well as the Equity curve/DD) based on user selected "resolution"! Current performance report "resolution" is "Trades" only, but having the ability to have it also on "Dai...

At the moment, one has to manually add a Holiday/Event for each and every occurence of it in the past and in the future.

Hi, Ming80, Where could one read that the "Generated" timestamp is for "when the exchange deems the order marketable"? Until now I thought that "Generated" is what it means i.e. generated by MC.

Hi Henry, I would like to reconfirm the following re 5-sec True RT bars: 1. Minute resolution: - IB API streams "bar updates" (i.e. O-H-L-C values) every 5-sec. How does MC update the bar in RT? My observation is that MC updates "Close only", and that 1-min bars received in RT and after subsequent r...

After some deeper searching the web, I did find the TS 8.3 EL Functions and Reserved Words manual. BUT: It describes onl...

Zheka

This has been a long time EasyLanguage legacy. It is part of programming's idiosyncrasies. Just ignore the zero and always start with one and you will be ok. This fact must be HIGHLIGHTED somewhere in the Arrays section of MC/PL documentation! https://www.multicharts.com/trading-software/index.php/...

Zheka

Actually, other basic array functions (VarianceArray and SortArray) process arrays from an index of 1 rather than 0!

Zheka

1. This link does not work. 2. I am not talking about Reserved words, I am talking about built-in studies 3. NO, Google does not return anything for these very specific implementations of these functions. 4. Why should a paying user spend time at all searching for something that should be documented...

Zheka

Oh..REALLY?

The only place built-in functions/studies were described must have been in the Easylanguage "Function and Reserved Words Reference" on the TS site.
And the link is dead for at least a year.

5-sec forex data is way too slow for high frequency trader (scalper). It seems to be an IB datafeed limitation, not a multicharts limitation. Other datafeeds don't have that delay.

Hello Zheka, We have double checked it for you and we can confirm that the bar is "closed" by MC when the "opening" tick arrives.

Hi Henry, I see 3 possibilities: 1) if current rules apply and a bar is "closed" by MC when the "opening" tick arrives, then it will be closed at +5 sec vs. the "timely" end of a bar period. 2) MC treats the last update for the bar as an 'opening tick' (because it arrives with a 250-300ms delay) and...
