how to check previous bar AccountFreeMargin

New comment
 

Anyone has a clue about how to check the previous bar AccountFreeMargin ?

It is working well to avoid trading twice on a bar for now using the following:

if((AccountFreeMargin()/AccountEquity())>=0.99)NoPositions=true;
else NoPositions=false;

but I cant figure out how to have the same for the previous bar because I dont want the system to open a trade on bar T and then on the next bar T+1 right away.

I have tried the following:

if((AccountFreeMargin()/AccountEquity())>=0.99)NoPreviousPositions=true;
else NoPreviousPositions=false;

but obviously it is not working......

can somebody help ?

thx and regards,

AccountFreeMargin() provides current value only.

If you want to know past value, there are two choices:

1. Going forward, collect values you will want to reference in the future, and store them (easier)

2. Calculate past values by examining trade history (more difficult)
