Bollinger Bars

20 DEMA line acts as a support if current price is above the 20 DEMA. Upper bollinger bands which stands at 2 Sigma (Deviations) will act like resistance in 95% cases.  Lower BB which stands at 2Sigma acts as support at 95% cases. Width of the band determines the volatility. 

BB squeeze (minimum 1 month, higher the better) - If the squeeze is for a longer duration, and if the current candle breaks the upper BB then it is a buy call.

Stop loss will be determined in the same way and trailing stop loss will be equal to previous day's candles low.
