I can't tell you if it's right or wrong because I'm not 100% sure what you want to do.

What your code will do though is found the number of buy positions and sell positions open across all active bot instances and won't open a long position for any symbol if you have a long position open anywhere in any account; likewise your code won't open a short position for any symbol if you have a short position open anywhere.

Yes, perfect! that's exactly the idea. Thanks Firemyst

If you don't want positions of the same symbol to overlap, then you need to find all positions first of the current symbol, and then doing a Positions.Count on that.

Doing a generic “Positions.Count” will count all open positions, even if you have several not open on the current symbol your bot instance is running.

For example, you could have an AUDUSD position open, a EURUSD position open, and EURJPY position open. If you only want to limit your bot so that you don't open another EURJPY position, then you need to search all positions that are just EURJPY.

Example:

int numPositionsAlreadyOpen = Positions.FindAll(p.Label, Symbol.Name).Count();

Hope that helps you even more :-)

Thanks Firemyst, that's also very helpful. I found something like that in the forum.

For now, I will apply this logic by grouping the long and short positions separately, in order to decrease exposure at times where the pairs are correlated. According to the results of QuantAnalyzer, this would greatly soften the portfolio curve, but I don't know how much to trust those hypothetical results. I'll try it first in demo.

I added it like this in each cbot. Please correct me if that´s wrong:

protected override void OnBar()
{   

var longPositionsCount = Positions.Count(p => p.TradeType == TradeType.Buy);

var shortPositionsCount = Positions.Count(p => p.TradeType == TradeType.Sell);

if (longPositionsCount == 0 && ShouldEnterLong())    { logic }

if (ShouldExitLong()) {CloseLongPositions();}

if (shortPositionsCount == 0 && ShouldEnterShort())    { logic }

if (ShouldExitShort()) {CloseShortPositions();}    

}

Hi there,

It would be simpler to check if there are any positions open instead of using this method. You can use Positions.Count to do this.

Best regards,

Panagiotis

Thanks Panagiotis, I'll try it and see how it works. I know more about trading than programming, and ChatGPT helps a lot, but sometimes it overcomplicates things.

Happy end of year.

Kind regards, Santiago
