On all the time frames from M30 to H12 volatility is very low but on the 4H it hasn't been under this value since Jan 2017 so we expect to see high volatility in the next 24-48 hours. How can you trade this? You use Stop Buy above the upper band and Stop Sell below the lower band. This is not the most accurate strategy, usually there are fake-outs so don't forget to put a stop loss. We will place our orders above the green band and under the red band.
