I'm trying to import Yahoo! data for the symbol ^NYA - the NYSE composite index.
The *.csv Volume field has NYSE total volume that currently is running around 2 billion shares/day. When I examine the *.csv file in Excel, the volume is different from day-to-day as expected. BUT when it is imported into AmiBroker, most of the volume numbers are all the same - around 2.147. . . billion. My suspicion is that this is a 32 bit signed INTEGER data type. 2^32 / 2. Is this correct? My goal is to use the volume to construct an A/D line for the NYSE. A/D involves adding/subtracting - but if I'm up against an internal limit of AB maybe that is not possible. Any suggestions?? Ed Hoopes AKA ReefBreak
