How to check Account Market Position for specific instrument?

[Mike0405]

Hi,

I know that if I run the same strategy on say, 4 different ES charts (ie. 2-min, 5-min, 30-min, 60-min), but I want to open a position in any of those charts only when I am flat in my account, I would use PositionAccount.MarketPosition == MarketPosition.Flat before entering a position. That way, there would be no possibility of me accidentally going short ES on one chart while being long in another (and thus ending up flat altogether).

However, what if I want to add 4 more charts with this same strategy but on a different instrument? Let's say oil (CL). Now, I would want to know, before opening a position, whether I was flat IN THAT PARTICULAR INSTRUMENT. How would I go about doing this? What would be the line of code that would query my ACCOUNT market position for a specific instrument?

Thank you in advance! This forum is great!

Hi Mike0405, thanks for your post.

The PositionsAccount object will keep track of this. Its an array and will hold info on all of the instruments you have a position in:

e.g.

for(int i = 0; i < PositionsAccount.Length; i++)
                Print(PositionsAccount[i].MarketPosition);

You can also edit the strategy so that it works upon two instruments at once, this might be more straight forward. Heres a guide on multi time frame and instrument scripts:

Please let me know if I can assist any further.
