What chart settings do most daytraders use and over what period?

Answer 1

The "Turtles" used to compare the current trades to a 50 or 200 day moving average. If it breaks above or below the average, go with the flow.

Answer 2

I think they generally trade a "breakout" system. This is where, as the previous post said, the moving average of the price (this is average price for the last hour or so) goes up sharply. This sometimes signals the start of an upward trend in the price, and if you buy then you can make money.

That is the theory. But 90% of traders, especially day traders, actually lose money.

Be careful.

Answer 3

Your question is a little vague. The general rule is to look at longer time frames to find stocks of interest and to use smaller time frames (say, 5 minutes) to time the buy/or sell.
