Greg: I was 
thinking that your original statement
<SPAN 
class=900054615-21042002> 
sell = 
Ref(Buy,-20) rather than what you tried sell = Ref(Buy,20);
<SPAN 
class=900054615-21042002> 
Did you ever try 
this?

Hi,
 
I think I've got it now. My use of <FONT 
color=#0000ff size=1>ExRem was 
messing me up. 
 
This seems to work ok.

- Control length of trade

Hi,
 
Been trying a few things for the past 3 hours but 
can't seem to get it right. Please help before I get divorced :) 
.
Trade Rules:
 
1. Buy at open on first monday of 
month.
2. Sell at open on Friday 4 weeks later (sell 
after 28 days). That's sell after 20 bars . I think ?
 
Pretty simple. But I guess I'm even moresimple:( 

 
I've tried   sell=ref(buy,20). 

<FONT face=Arial 
size=2>               
sell = barssince(buy)=20
 
and various other tthings, but I'm getting 
nowhere.
 
Here's what I've got so far.
