[amibroker] Re: Identify bar for actual Buy

Hi

The bottom line with this is that I want to be able to set a stop and 
have control over it.

After thinking it through, I decided that the first step was to set 
the stop for the first Buy signal and keep it at the same value until 
a Sell signal and then set it to 0 again.

Seemed like a great theory but the stop value is reset at each bar 
and therefore does not maintain a constant value.  Maybe it is a 
mindset thing - my professional experience was with procedural 
languages and AFL taxes my thinking processes sometimes - maybe 
something about teaching an old dog new tricks...

Anyway, the snippet of code for setting the stop is as follows

Buy = Ref(vaValidEntry,-1) AND Low <= Ref(vaLimitEntry, -1);
BuyPrice = Min(Open, Ref(vaLimitEntry, -1));
vaIStopVal = ATR(vISATRPer) * vISMult;
vaInitStop = 0;
vaInitStop = IIf(((Buy == 1) AND (Ref(vaInitStop, -1) == 0)) , 
BuyPrice - (Ref(vaIStopVal, -1)), Ref(vaInitStop, -1));
_TRACE(" | buy: " + Buy + " | stop: " + vaInitStop + " | PrevStop: " 
+ Ref(vaInitStop, -1));

Any ideas as to where I've gone wrong and why it is resetting the 
value each bar, please.
