zabeen when first i installed gls my old indicators not working.then i tried to compile the indicators no use, some indicators not showing any errors in compiler but not working.
finally i downloaded mt4 directly from metaquotes and enter gls id and password and enter ip address in server and loged in then all indicators are working now.
i dont know what problem but working well. only problem we can not send and receive mails from gls. but for that i kept old gls installation without chart for checking mails.
there is difference in working in windows xp and win8
