MultiCharts: Trading Software for Automated Trading and Backtesting

bluefightingcat

Well at this point I have 48gb of RAM and a hexa-core i7-5820K overclocked to 4.1GHz. Based on my experiences so far it seems that the biggest issue is getting the information from IQFeed fast enough into MC. If I have understood correctly MCs is very slow with moving information around. The process...

I agree with fbertram. In addition to Multicharts I use competing software that is substantially faster (I think posted the exact times somewhere in previous posts). Clearly it's possible to fix this. Maybe Multicharts is just built in away that makes it hard to get this fixed.

hughesfleming: This is really interesting. I've very inexperienced with these things but from what I understand you are just renting a computer (server) from the company in Frankfurt. You then install Multicharts on it and run things as usual? How do you connect to the server. Is it essentially like...

I have a strategy I want to run on initially 500 US Stocks and later on, on as much as 6000 stocks using hourly data fed by IQFeed. The strategy is relatively simply: - If the open and close of the bar is below a certain threshold (at the end of the time unit) e.g. simple moving average, then buy at...

I wonder whether the Multicharts team has looked into this at all?

bluefightingcat

I run Multicharts on my desktop computer. However sometimes when travelling it would be useful to run Multicharts on my laptop. I was thinking it would be great to install Multicharts on my "OneDrive". This was I could run Multicharts from either computer with all settings saved etc. Do you think th...

Have you had any progress with this since your post?

Unfortunately the documentation on the money management signals is quite limited. I am having a hard time figuring out the link between a Strategy's normal "signal" code and the "money management signals" code. How do they talk to each other? For example in my signal code I have the following: pmm_s...

I've posted a "feature request" regarding this here:

https://www.multicharts.com/pm/viewissu ... no=MC-1987

If you're interested and think this would be useful go and vote!

bluefightingcat

Yes exactly. (I am indeed using a signal not an indicator in backtesting). The problem is that to compare two different backtests using two different indicators say one that uses 100 days and one uses 40 days, I would have to manually count the bars backwards to make sure that bar 101 and 41 are on ...

bluefightingcat

Hi, I have a study with the following code: PR = 100*PercentRank(RateOfChange(C,1),RateOfChange(C,1),iLenROC+1); The only input is the iLenROC and for that I use a default of 100 bars (i.e. 100 days in my case). However the result that is produced when I plot this study is rounded to the closest int...

bluefightingcat

I am trying to figure out the logic of how backtests are done with regard to referencing. I have an indicator that references 100 bars back. I use daily bars and I want to run a backtest from 01Jan2015 to 31Dec2015. Does MC automatically reference 100 days before 01Jan2015 so that the indicator show...

bluefightingcat

Thanks TJ.

I came up with +1 idea myself but it doesn't work with the rest of my code. Your previous suggestion seemed to be better in my case!

bluefightingcat

I am having trouble finding a nice solution to the following. I want to count the number of bars since a certain condition happened. e.g. I want to count the number of bars back when close > close[1]. I try and achieve this using the function MRO. However according to the Easylanguage guide MRO will...

bluefightingcat

One more vote from me!

It's a really pity because I quite like multicharts. But somehow it seems that it was major limitations for backtesting huge amounts of data.

bluefightingcat

Well I can give you direct comparison using competitive software (costs about double what multicharts costs but also comes with porfolio testing including money/portfolio management). Same strategy (or as same as it can be using different coding languages) same amount of stocks and same amount of ba...

bluefightingcat

There is huge potential to optimize the code here...

This definitely seems to be the case.

Unfortunately importing is not really an option because I would have to manually import 6200 symbols x 2 (1 minute data and 1 day data). That would take me forever. That's why I have mapped the ASCII data.

bluefightingcat

I am hoping somebody more informed than me can explain why it takes so long to backtest using ASCII data?? So I've downloaded all my 1 minute and 1 day data to my SSD using QCollector. I've ASCII mapped all my US stocks (all 6200 of them). Can somebody explain what Multicharts does whilst it is "loa...

bluefightingcat

Not sure how Multicharts versions evolve. If we are at 9.1 now then do I have to wait for 4 minor updates for this to be fixed? Any ballpark idea when we can expect this?

bluefightingcat

Was this ever implemented?

bluefightingcat

To make things a little clearer, this is what I would do when I trade manually: - I would open up my scanner 15 minutes before market close. - I would search for all stocks that have a daily RSI(14) that is below 5 at that moment. - I would buy the stocks based on some other minor criteria. So based...

bluefightingcat

You might "think" you are trading on a daily chart. But in reality, your analysis, your system, your criteria, are based on a 15 min system. Care to elaborate? If I setup a watchlist in the Multicharts scanner with a stock using "1 day" resolution and add a study to my watchlist to calculate the RS...

bluefightingcat

Ok. Imagine this strategy. I want to buy stocks 15 minutes before the NASDAQ and NYSE close. I want to buy the top 5 stocks with the lowest RSI(14). I want the RSI to be calculated "in real time" based on "1 day" data. However I also want to be able to buy the stock before the market closes i.e. as ...

bluefightingcat

So what would be the most accurate way to backtest?

bluefightingcat

Hi, I was wondering whether which would produce more accurate results in Portfolio Manager backtester considering that barmagnifier is not available in Portfolio Manager. My strategy relies on 1 day data to find entry signals but I want to open a position as soon as the entry signal rule is met and ...

bluefightingcat

One possible scenario is that the system is only ignoring one of the datafeeds for the affected instruments instead of both/all datafeeds for the affected instrument.

bluefightingcat

What about IOG in backtesting?

bluefightingcat

Can somebody please tell me how to turn on the bar magnifier in Portfolio Trader for backtesting purposes.

I've read this https://www.multicharts.com/trading-sof ... _Magnifier

but it doesn't really talk about the backtester.

Here you can find all stocks listed on the NYSE, NADSAQ and NYSE MKT

I've come across an issue. I'm not sure whether I am doing something wrong or whether this is bug. I am trying to run a backtest on stocks using 15min as data 1 and 1 day as data 2. The chart information is downloaded and I've set my strategy max number of bars the study will reference to 50. Of cou...

bluefightingcat

Thanks for making things clearer. My data1 is currently 1 day resolution. Would I need to add another dataset e.g. 1 minute resolution to be able to IOG? Would it help if I build the 1 day resolution from minutes? How exactly do I turn on IOG? I've add the command to my code but when I got portfolio...

bluefightingcat

I am trying to backtest my strategy in Portfolio trader. Essentially it contains entry and exit rules based on 1 day data. However my understanding is that you cannot send a buy or sell signal during the same bar. I would have to wait for the next bar and using 1 day data that would mean waiting unt...

Wrong tool for the job.. Don't bang a nail in with a saw. MC is handy, but its not for what you're attempting to do. Hi Maverick, Can you elaborate on why you think Multicharts is the wrong tool for the job? I mean as long as I have a powerful enough prosessor and enough RAM and a decently fast dat...

bluefightingcat

Trading an index would be different. What I am trying to do is go through all NYSE and NASDAQ stocks and see which ones fulfill my entry requirements and then to buy the ones that do.

Hi, Well I'm backtesting through the entire NYSE and NASDAQ stocks. QuoteManager seems to indicate that there are actually approx. 8000 of them. However I seemed to have found the issue. I am still using the trial version of IQFeed which seems to have some limits. I shortened the backtest timeframe ...

Hi, I am trying to run a backtest and I have the setting "download data before backtest". I use IQdata as my datasource and I have about 7000 instruments with 1 day and 15 min resolutions. I am backtesting to 1/1/2014. This is the first backtest I am running so all instruments need to be downloaded....
