anyone can advise me on this problem that I have? Not sure if it's some settings in amiquote or amibroker but I don't used to have this problem in the past. Now everyday when I update the amiquote, some of the tickers will have the weird volume trending.
This may be because of the fact that you have imported PAST data bars with volume specified in hundreds or thousands of shares, and now you are importing data without multiplier. You need to check if import definition has $VOLFACTOR line. For more information see:
Thank you very much. It works well.
