I have 12 symbols in my database with intraday quotes going back beyond 12 months. I really only want to maintan about 1 months worth of data for each symbol. What is the easiest way to remove these quotes? Quote editor takes too long and in fact does not work because it hangs Amibroker.
Actually probably the best way to handle this is to remove all quotes for all symbols and then just use 30 day backfill to maintain one months worth of data. So what's the easiest way to remove all quotes from the database (I don't want to have to recreate the symbols)
