Hi Clement
I wish I could take credit for this, but as I mentioned, I can't - it
was given to me by Walt who frequents this board.
Yes, this stop is easily adaptable for short positions. Here is the
code. See the pct line for the changes.
shortat=shortPrice;
MinGainPct=.04;
trailPct=15;
pct=IIf((shortat-MA(C,2))/shortat > MinGainPct,trailPct,9999);
ApplyStop(stopTypeTrailing,stopModeRisk,pct,1,True);
Re: your question about the stop changing throughout the trading day, I
am not sure how it would respond if applied to intraday data as I use
only EOD data myself. However, I don't /think/ it would matter - the
code should behave in the same manner. Someone else who is more familiar
with the 'shortprice' world may be able to help you if you run into
problems. Good luck with it.
