valuewhen(buy,....)

["Franco Fornari" <ffpsi@xxxx>]

Hello,
 
I noticed a possible trouble, using valuewhen() to 
refer to the last buy. It seems that this function is referring to the 
last buy condition, wich is not always that one signaled by the last green 
arrow. Frequently, a trading system can detect a few buy conditions, beforeto 
generate a "sell". But I need to refer to the last green arrow and not to the 
last buy condition. How can I do it?
 
Best regards,
 
Franco
