Re: [amibroker] Please help with Premarket Volume analysis

["emp62" <emp62@xxxxxxx>]

hi,

you will have to do something like this (didn't test it but it gives you the 
idea):

// save pre market volume in an array
preMarketVolume = IIF(TimeNum() >= 80000 AND TimeNum() <= 92500,V,0);

// in the 1 minute chart sumate this volume
sumPreMarketVolume = SUM(preMarketVolume,90);

// now derive the total premarket volume at 92500
totPreMarketVolume = IIF(TimeNum() == 92500, sumPreMarketVolume,0);

This should work on stocks like the QQQQ

rgds, Ed
