How to code close after x bars

Hi,
I think this is something pretty simple, but I've looked everywhere and can't find an answer.

I'm trying to test some expert advisors and all I want is the code to close an order (Either a buy or sell) after 8 bars.

What would be the code for this?

Thanks

The first thing I'd try is to use the OrderOpenTime() function, along with Period() and Time[0], then just calculate the number of bars since the order was opened. If >= 8, OrderClose.

Sorry I'm a complete noob so I don't really fully understand how to implement your advice.
I'm trying to do this in metatrader 3 and I can't seem to find any of those functions in meta editor.

Even if I could find them I wouldn't know exactly where to put them in order for it to work.

Also, when I try to strategy test, it will end up testing it from 2003 up to the present day :O, that's a bit too far back. I want to try testing on a much smaller time scale, any tips?

thanks,
steve

I don't know anything about MT3, sorry.

Basically, you look at order open time, at the time of the current bar, find the difference, divide by the timeframe of the current chart * 60 (converted to seconds), and you have the number of bars that have passed.

that helped a lot, thanks.

I think I've sorted out the problem. How does this code look:

var: TradeBars(8); // Returns the number of bars the trade has been alive

// Note: THIS ASSUMES THERE IS ONLY 1 OPEN TRADE !!!

if( (TotalTrades!=0 ) and (LastTradeTime!=0 ) ) then
{
tradeBars = Round((CurTime-LastTradeTime)/(Period*60));
}

return(tradeBars);


"8" (In bold) is the part I changed, so it should work now.
