Xi's words triggered my thinking. I thought about how much indicators accounted for in my trading system? Did they play a reverse role in my judgment of the market? Did the indicators of the orders that made money have any substantial contribution?

In the past, I used indicators as a reference before opening orders. If several indicators met the conditions for opening a position, I would open an order. But I thought about it again. In order to wait for the indicator to open an order, I also missed a lot of market conditions. Indicators lag behind the market and prices, and indicators will change according to price changes. It is not that opening an order can guarantee profits. Most powerful indicators do not conform to the principle of trend trading, which makes it easy for you to guess the bottom. The risks behind them are actually huge. My larger profitable orders are actually obtained by entering and exiting the market through volume and price naked K analysis, and there is not much about indicators. (Strategy)

Later, I found that the biggest impact of indicators was actually my execution and mentality. I didn't dare to place an order when the indicators did not come out, which greatly affected my execution. When the market had already appeared and the indicators had passed the best opening time, it greatly affected my mentality. (Why use indicators when you can make profits from start to finish by your own analysis?)

Even the strongest indicators will become inapplicable one day. In the end, trading is all about mentality and anti-human nature.
