[amibroker] backtest question

[triangle702000]

I'm trying to fine tune an entry method only for now,so to exit the 
trade I'm just using  cover=ref(c,5). I'm just trying to see if a trade 
will be profitable five days after being initiated. First,I ran a 
backtest using  cover=ref(c,1) which gave me the result after one 
day,but now when I try to change the assignment to 5 days or whatever, 
it still closes the trade after one day. Can anyone tell me what I'm 
doing wrong? Thanks.  -jim
