Hi Dean
Send me details of your expert and the problem off list (starting from scratch) and I'd be more than happy to help. You could post any results to the group later if you wanted to.
Regards
Roy

Roy...
If you could humor me... from what I was able to find in the MS
manual, in experts you can use local variable only inside WRITEIF's
and WRITEVAL's. Am I missing something.... BTW I am a MSTT
subscriber, but have not fisnished reading all the back issues. If
you have written details on experts and what I am trying to do,
please point me in that direction. But it sure would be helpful if
you could specifically add the init routine into this code which is
part of the EXPERT I am working on
----------------------------
The most recent High Beta was writeif( BarsSince(Fml( "!QUTSH -
Setup Day - High Beta") ) < BarsSince(Fml( "!QDTSH - Setup Day -
High Beta") ) , "an UPTREND" , "a DOWNTREND")
----------------------------
Thanks for your help...
Dean

BarsSince(Event B). Typically Event A could be Buy and event B a
Sell, but not necessarily.
