Didn't say it wouldn't work, just said it's a poor choice because there's a 66% chance that a daily TR will include an overnight gap and those are irrelevant when you are daytrading.


Quote from Podimer:
From my personal experience, after comparing intraday high to low and ATR on 50+ of the most liquid stocks over 2 months, it showed an average difference of just under 5%, higher during earnings season and dropping back down in "business as usual" periods.
Either way, ATR should be good enough to tell you if there is enough play within a stock to make some money. If you also want to know liquidity of the stock (for your tight bid-ask spread), there are a few different types of volume measures you could plug into this scanner.
Good luck

Stockfetcher.com is great for this. Its cheap, easy to use, and has a forum section where people volunteer codes and discuss similar things.
you can use ADR in this case.
or if you want more detailed info there are various user-made scans, that show the various % moves from the open (up or down) , in the last 100 days, and how many times in the last X amoujnt of days, it has behaved such..
you of course, enter price range, average volumes, etc..
Check the author TRO's "run forest run" thread if you do. All your needs will be met.
