1) Add Bollinger band indicator to the price chart;

2) Wait when the price has moved outside the indicator;
3) After the price has returned inside and a confirming candlestick has been closed we can open a deal directed towards the central indicator line;
The upper and lower Bollinger bands can be used as the levels of support and resistance.
