insaneinvestor: it depends on your strategy. If you are buying retracements for instance, then, when the daily range contracts it means that the market is moving slower (shallower swings, longer than usual retracements) and you need to slow down your pace also, meaning go with a longer timeframe. If the market is moving faster and the daily range expands, this means that swings are wider, pullbacks quicker and faster so you actually need to get faster in your trading by using a smaller timeframe. good luck
I actually think 80 points is a good range in a day, esp for a newer trader. Chances are though that to make money in that range you will need to be fast. (a few hours at most) At least from my limited experience. Something that has a range of 80 points for example may close with only a 10 point (or less difference) from the open. I simply wanted to say that this person may consider something with a greater range, however there is a price for everything.
Darvas Box works well in chop as well as 123 break line's Drop chart down to 89 tick or 1 min and take quick profits ! you will need also to put more than 1 market up I stack the market on top of one another when they break together take the trade !
