I am fond of entering on a crossover of the price over the 18 day moving average, with a sharp up turn of the 4 and 9 bar at the same time. I use the Bollinger Bands to signal my exits. I prefer to trade the intra day swings, rather than over all trends.
I also like to do contrarian trades on sharp turns of the 4 bar moving average if it is aimed directly into the top, or bottom of the price bar.
