hi my friend .. Parabolic Sar is one of the most good reliable indicators .. notice about it ( its fro my own experience parabolic Sar when it begin the circles be a way from the candle and it make about 20 circles as a average before it give an opposite signal ) using on eur/usd on 1 hour chart and its best setting is 0.03 and 0.3 .. happy earns my friend ..
