The buy signal is the point at which the price breaks out over the 20-day high, and the sell signal is the point at which the price breaks out beneath the 20-day low. This is exceptionally straightforward, yet there is as yet a major downside. Specifically, new highs may not result in another uptrend, and new lows may not result in another downtrend. So we are going to encounter a considerable amount of bogus signals.
