go to properties and see if you can set UseHourTrade to =TRUE
I believe if you want to use GMT and your MT company is using gmt you can just put in the hours you want it to trade
StartHour 7
EndHour 18
in properties
if your charts are not based in GMT you have to calculate the shift
by the code you pasted it dont appear to be lacking
lemem get the source and look at it for the cross i told ya wrong for the way the alerts are coded there
