1.Identify trend then go with the trend 2. guess where trend might stop and play the reversal 3. rangebound scalping All three and then some, best are failures for me where are the unskilled, immature, dreamers stops are of current position and I be glad to let them out of losing position only to go in direction they wanted to go in first place. Life is only grand with knowledge.
Joining in the crowd saying all 3, if you trade intraday you have to be flexible and take the trades the market offers that day. Or be very picky if only trading 1 of the styles. Doesn't matter if you made a killing yesterday trading breakouts, you'll be killed if you buy the top multiple times in a trading range day.
