A false breakthrough is when the chart goes beyond the support and resistance levels but then returns to the price corridor.
Look carefully at the chart to distinguish a false breakthrough from the real one.
If the candlestick closes below the support level or above the resistance level, so that approximately ¾ of its body is outside of the price corridor, then the breakthrough is real.
If the candlestick closes below the support level or above the resistance level, so that less than ¾ of its body is outside of the price corridor, then the breakthrough is false.
