closing a trade after a number of days

[eetest]

Hello,

I'm using Formula Wizard to back test a simple price based strategy, I need the strategy to close after lets say 10 days (or after a given number of bars), is this possible?

It is possible but you will not be able to code the required logic using the Formula Wizard alone

Ok, What do I need to add to the code then?

The first thing you would need to do is create a global variable (ie declared outside of function main) called for example vCounter and set it to 0 ie var vCounter=0;
Then in main you would add one of the following two examples depending if you want to count days or bars.

//if counting days
    if(getDay(0)!=getDay(-1)&&getBarState()==BARSTATE_NEWBAR){//if new day and new bar
        vCounter++;//increase the counter by 1
    }
    
//if instead counting bars
    if(getBarState()==BARSTATE_NEWBAR){//if new bar
        vCounter++;//increase counter by 1
    } 

Following that you would have your trading conditions/logic to which you add the command to reset the counter to 0 when you enter a trade. At that point you verify if the counter is at the desired value at which point you implement your exit strategy (see following example)
Alex

if(!Strategy.isLong()){//if not long
        if(your condition==true){//if condition to go long is true
            Strategy.doLong("Long",...etc)//go long
            vCounter=0;//reset the counter
            //other commands if required
        }
    }
    if(vCounter==your number of days/bars){//if counter is at the desired value
        if(Strategy.isLong(){//if long
            Strategy.doSell("Sell"...etc);//sell
        }
    }
