when it sees several buy signal in a row. Here is my test system.

BuyPrice =Ref(LLV(L, 3), -1) ;
Buy =Low<BuyPrice; 
sell= ref(buy, -5);

It can geneate several signals in a row. When I test it on BA, I got 
6/29/01 entry and 6/29/01 exit.

a "position" function to describe current position (long, sort, 
neutral). Then I can write
Sell=barssince (position=1)>5;

Thank you,

Bai

Since it can generate several buy signal in a row so sometimes the 
system close when
