The Simple Moving Average(SMA): These indicates buy signals when currency prices rise above the average line. Sell signals occur when the price falls below the moving average line.
Bollinger Bands These indicates the potential changes in the foreign exchange market. Sharp price changes tend to occur when the bands tighten while prices that touch one band tend to go all the way to the other band.
