I use RSI indicator 1M, 5M, 15M. Calculate the RSI average 1M, 5M, 15M. And with this, calculate the Sinus like the RSI is an angle, because, when he reach the min or max level (10 / 90), you can figure there is more chance it will change side. So I open an order to the other side, and close when the side change (sinus change angle) or if I touch the Min/Max level
