MultiCharts: Trading Software for Automated Trading and Backtesting

pcrespo

Here's what I've been doing to successfully auto-update the margin. In the same PT portfolio as my trading strategy, I run the following strategy in parallel on the same instrument: [AllowSendOrdersAlways = False] input: acctCode(2); vars: intrabarpersist LBOC(false), intrabarpersist sentEntry(false...

I've thought of a solution available to some people, requiring the ability to simultaneously trade real and paper. Have a paper strategy enter a position however often the margin changes. Use the existing commands to find out the initial and maintenance margin. Then pass that info to the real-money ...

Bump. Was this ability ever added?

I take it back: it doesn't work. It sends the "disconnected" alert whether you're connected or not. It fails because the command RejectedOrderCategory always returns 0 even in the presence of a rejected order, whether trading from PT or the chart, with IOG on or off. If that command were to actually...

pcrespo

It worked! I wrote a signal based on my OP. Last night, IB disconnected in the midnight hour and failed to reconnect. (It seems to happen more on Sunday nights for some reason.) My signal detected that and sent me an alert. //Sends a purposely rejected order to test the connection. //Use a current i...

pcrespo

Say at 1:00 AM you send an invalid order of some sort. If you're connected, the order will get sent and rejected, and you can use a command like RejectedOrderCategory to detect that an order was rejected. If you're disconnected, the order won't get sent to broker in the first place, and the command ...

If I use 4 PT windows, will that use 4 cores?

pcrespo

I suppose it's two strategies: a one-hour entry strategy and a smaller-timeframe exit strategy. We could achieve basically the same thing with stop-limit orders and "SetTrailingStop_pt", but I just remembered we have a good reason not to do that. I'd share the reason, but I'm not sure if my colleagu...

pcrespo

It's definitely possible to use the swing high. Are you asking how to code a swing high function? (Because once you have that, coding the strategy you describe would be very easy.)

pcrespo

Getting to a more granular time-frame will not solve the problem of "delays" - it will most probably make it worse/ more frequent. I made it less granular, not more. It was 1s and then I made it 15s after your earlier post. And - by the way - delays are not "bad" by default. Depending on your syste...

pcrespo

Heh I mean, I'm making the same number of trades (paying the same commission & slippage) regardless of my Data1 interval. It's just, when my signal says it's time to enter/exit, I'd rather not wait. Are you saying the Data1 interval should be at least a minute? Either way, if the delays persist, som...

pcrespo

Earlier today, there was a delay that did not correspond to an IQF disconnection, so unfortunately there remains a mystery cause. @Zheka - I didn't realize it was hard for the system, since MC is allegedly capable of trading on tick charts. If it can handle ticks then 1-second should be a piece of c...

@pcrespo, What's the bar interval for your primary trading logic and what would be your typical trade length? Sorry I missed this question before. Currently I have two signals trading. One of them trades 4 instruments using 1-hour Data2 bars while the other trades one instrument using 1-min Data2. ...

@pcrespo, Thanks for posting your code. I will run it as well and let you know if there are any issues. My server is in Frankfurt so about 100ms worse in terms of latency than yours. Have a good weekend. Alex Sorry for the mess of a code. This new code ought to achieve the same thing (good suggesti...

pcrespo

Ok I've tweaked my code, and in Registry I increased the sync interval to 1024 seconds (I can't get SpecialPollInterval to work despite using the 0x1 flag, so I have to use powers of 2 via the min/max poll interval). @Zheka - the thread you linked to indirectly provided a big clue. I hadn't thought ...

pcrespo

@wilkinsw - my delays have been happening since the beginning of the year or maybe late last year, so for me it has nothing to do with version 12 R2. @Zheka - you make good points. I should only log delays (defined by my inputs), rather than log the delay at every bar close. Syncing every 16s is pro...

pcrespo

Who marked this as Solved? It's not :( @Svetlana - I'll enter the livechat Monday or as soon as I can. I have CloseBarTimeout set to 3. I'm syncing the machine's clock with us.pool.ntp.org every 16 seconds. So far, my log shows a few several-second delays, for instance there was a 9-second delay des...

Update: I'm setting up a newly rented dedicated server. This one has an E3 1240v6, is located close to NYC, and is cheaper. It's from a different provider, just to eliminate a variable (though I have zero complaints about OVH). But before I get to the Moment Of Truth, I'm curious about something. IT...

pcrespo

@TJ - dedicated bare metal. @Zheka - quad core was the lowest available from OVH. I'll shop around for a server with faster (and possibly fewer) cores. Given that the data was streaming on time when the recent delay happened, I don't see how the problem can be with IQF. Also, switching to IB data wo...

pcrespo

So today, a long delay happened when it was time to exit a position. Trading ES on a 1-second Data1 timeframe (sync mode, IOG disabled), we were supposed to exit at 16:00:01 but instead exited at 16:00:54 even though there was plenty of volume (and thus, opportunities for the signal to calculate) in...

pcrespo

@Alex - I've turned FastTracing on for good measure, but the problem must be unrelated because the calculation delays happen under all conditions, not just during trades and not just during high volume. They happen when trading just one instrument - any instrument during any hours. Sometimes a delay...

pcrespo

I don't have an IB data subscription. I can only open a chart with IQF symbols.

Edit: oh you probably mean in TWS not MC. I'll look into that.

pcrespo

I don't use my power of thread resurrection often, but this may be a good time for it. The method proposed ITT to detect a disconnection doesn't work for me in 2018. I tested by manually disconnecting from IB API. No alert, because my signal still prints getappinfo(aistrategyauto)=1 after the discon...

pcrespo

Changing the time sync settings hasn't gotten rid of the delays. I think the delays are real, not just a matter of the PC time being inaccurate. My ping to the IB server is 15ms, but if anything, the delay is with IQF, not IB. The signal's calculation is delayed, suggesting that I'm either receiving...

pcrespo

Changing the order of PT instruments didn't get rid of the delays. I like the time sync suggestion. For now, I've changed the NTP servers to the appropriate pool.ntp.org ones and changed the polling frequency to 1min instead of 1hour. If that doesn't work, I'll investigate whether the server time is...

Do you have IQFeed and Multicharts excluded from the antimalware service? Windows Server 2012; we have no anti-malware installed (Defender is not included by default).

I'm running MC 12 with IQF data and IB API, trading in PT. The changelog for MC12 indicated that this issue might have been fixed, but for me it persists. I've been logging this issue as follows.

I'm paper-trading and this warning has been flooding my MC log for weeks, at all hours. Is there any way to get rid of it or tell MC to stop trying to cancel the non-existent order? What even causes it? I use Interactive Brokers and the latest version of MC and the IB API. When I open Trader Worksta...

If I'm not mistaken, the unit for the parameter of "setstoploss" is currency, not points. EntryPrice and Close are in units of points. I think all you need to do is multiply by bigpointvalue (a reserved word), as in: setstoploss( EntryPrice * StopLossPct * bigpointvalue ) Make sure your settings in ...

Does anyone know of a data provider (at least for futures) that sends price information for 0-volume bars? I ask because I was hoping to trade in Portfolio Trader instead of from a chart, but I can't use IOG in PT, so I'm considering switching providers so my signals can send orders without waiting ...

pcrespo

You're right! Try the following: Set a date block in your code and only have it start when the chart date >= this date. Set this date to the beginning of 2016 and start your chart a couple of month earlier. I took this concept and did something similar: I started calculating after currentbar > N. Wi...

pcrespo

Then take your best estimate and add 50 to it.

My point is there are two seemingly contradictory facts:

1. DMI's true lookback exceeds the input length.
2. When I set MBB=Len, there is never an error message.

pcrespo

Don't know. You should just leave it on auto.

I'm using Portfolio Trader. I thought PT didn't have auto mbb?

pcrespo

Why do you think when your simplistic singular input Len=5, that your complex multi-layered indicator's ACTUAL total look back should also be 5? I thought I have already explained to you in prev post. You did, and I'll fully grasp it after some more playing around. (Your last post made me wonder if...

pcrespo

If your DMI code is required to look back 100 bars to calculate the result, it will only look back 100 bars. It will not look back further than 100 bars. But then why, when I set the lookback (Len) to 5, do I get different DMI+ and DMI- numbers with MBB=5 vs MBB=10 (as shown in the two lists in my ...

pcrespo

If there is a function inside the function, and inside the function, there is an [1] appended to one of the variables, you are looking at MBB = Len+1+1... and so on. Ahh ok, I didn't notice recursion in the code. I saw the [1] but thought it was only going back 1, not 1+1+... I'll have to play arou...

pcrespo

Have you looked into the codes in DirMovement? Yes, several times now. Nothing I see makes me think it should exceed Len when looking back. Everywhere "Len" appears in the code, nothing jumps out at me. I also looked at the function "TrueRangeCustom", and still no clues. Below is the code, if you w...

pcrespo

Did you get the N+1 part? I took it to mean that when MBB = N, the calculation can't begin until the (N+1)th bar. But I see that the phrasing is different: N is the number of bars ago referenced . So if the calculation begins at bar N+1, does that imply that the Nth bar back is being used in the eq...

Please copy and paste the manual you have and we can go through it together.

You have a misunderstanding of the purpose of the MBB. Many people (esp newbies) make the same mistake. Please go back to the manual and study the MBB explanation again.
