[amibroker] checking if the realtime data is coming in

[murthysuresh]

i just put in this code to see if the realtime data is coming in or 
not. but strange enough it does not seem to work.


        if(Nz(GetRTData("UpdateTime"))  OR (GetRTData("UpdateTime")
<LastValue(TimeNum()))){
                Say("Not getting realtime data" ,False);
        }


when i shut down the IB plugin the explore window shows a blank value 
for the GetRTData("UpdateTime"). so why is the nz(GetRTData
("UpdateTime")) not firing....
