is it 
possible you are buying and selling on the same bar? To check you could turn off 
that option in settings.....

exrem??? Bug or (probably) user-error?Using this code, 
I sometimes get two consecutive buy (or short) arrows:Buy=  
condition1;Short= condition2;Sell= C<Ref(longstop,-1);  
Cover = C>Ref(shortstop,-1); Buy=ExRem(Buy, 
Sell);Sell=ExRem(Sell, 
Buy);Short=ExRem(Short,Cover);Cover=ExRem(Cover, 
Short);PlotShapes(IIf(Buy,1,IIf(Short,2,IIf(Sell,4,IIf(Cover,3,0)))),IIf(Buy 
OR Cover,colorGreen,IIf(Short OR Sell,colorRed,0)),0,IIf(Buy OR 
Cover,L,H));Any ideas why?In understand Buy=ExRem(Buy, Sell) 
to mean I can ONLY get a buy signal after a sell has been generated. So what 
happens if the next signal after a buy is a short? Is the buy just closed or 
is a short opened at the same time?Also, in a non-always in system, 
i.e. using cover and sell as stops, is the code marked *** 
vaild?Buy=ExRem(Buy, Sell or short); ***Sell=ExRem(Sell, 
Buy);Short=ExRem(Short,Cover or buy); ***Cover=ExRem(Cover, 
Short);Thanks.AndySend
