1. Bollinger Bands
Three MAs of the indicator form two bands. General idea of the strategy is based on the fact that upper and lower Bollinger bands are overbought and oversold zones respectively. After the breakdown of upper or lower MA the price is trying to go back to the middle MA of the indicator.
The breakdown of the lower line is the signal to buy.
Sell signal will appear as soon as the price chart crosses upper MA from below.
If MACD histogram crosses the zero line from above, it is a signal to sell.
Buy orders can be opened as soon as histogram enters positive zone.
