I think I have already explained the Bollinger Bands strategy very clearly before. After all, the necessary parameters for creating a strategy have been explained. Moreover, it's just repetition. The advantage of a strategy is not the parameter settings for placing orders and selling, but that it is not affected by the market like humans. It will not panic dump and will add positions to make profits. Those who have this mindset will achieve the same effect even if they trade manually. Those who don't understand it will terminate the strategy when they shouldn't, and add positions when they shouldn't. It may be better to run a strategy without looking, taking no action, and let it perform well. If you have any questions about the strategy, please leave a detailed comment, and I will reply collectively.
