Specifically, it goes long when the price breaks above the upper band and closes position when the price falls below the middle line. This is a typical trend following strategy.

Strategy Logic

1. Calculate 20-day Bollinger Bands, including upper band, middle line and lower band
2. When close price is above the upper band, go long
3. When close price is below the middle line, close position

The above is the main trading logic of this strategy. It is simple and effective to capture relatively strong trending moves.
