Re: [amibroker] problem with AlertIf() and GetRTData()

Hello,
 
I am wondering why don't you simply go to the HELP file in first place (before you started replacing one function with another)
 
Is it that hard to read the function reference ?
 
It says clearly:
"The function retrieves the LAST (the most recent) value of the following fields reported by streaming real time data source for specified symbol"
 
Best regards,

OK,
 
marcin at support@xxxxxxxxxxxxx gave me an answer. maybe it is of interest to others as well:
GetRtData() and GetRTDataForeign() do not return/hold ARRAYS but only LAST NUMBER. therefore one cannot use
these functions together with other functions like Ref() or Cross() because they need an ARRAY.
quite a shame, i will have to revert back to good old Foreign() which executes slower than GetRTDataForeign().

i recently converted a rather large formula from SetForeign() to GetRTData(), but now i can't seem to get my AlertIfs working.
Could someone help me out and tell me why this (example) code does not generate alerts in the alert output window?
 
thanks,
dirk
 

//example code pair BHS-BZH

BHS=100*GetRTDataForeign("Change","BHS")/GetRTDataForeign("Prev","BHS"); //percentage change since yesterday's close

BZH=100*GetRTDataForeign("Change","BZH")/GetRTDataForeign("Prev","BZH"); //percentage change since yesterday's close

BHS_BZH_trigger=2; //trigger value

AlertIf(Ref(Cross((BHS-BZH),BHS_BZH_trigger),-1),"SOUND D:\\AmiBroker\\Sounds\\alert.wav","Signal Alert on pair BHS-BZH (up)",1);

AlertIf(Ref(Cross(-1*(BHS+BZH),BHS_BZH_trigger),-1),"SOUND D:\\AmiBroker\\Sounds\\alert.wav","Signal Alert on pair BHS-BZH (down)",1);
