What is CAP Channel?
CAP Channel is an MT4 channel-band indicator that shows price movement between upper, middle, and lower bands. It marks reversal areas with blue sell crosses near the upper band and red buy crosses near the lower band.
How to use CAP Channel
Blue and red crosses on a three-line channel appear when price reaches the upper band for a sell signal or the lower band for a buy signal. Adjust the display colors if the default settings are difficult to read on a black background. Check a cross with the following candle or a price-action pattern, with applications from scalping to swing trading.
