For those who are using trading indicators and want to combine them correctly:

1. You must understand which group the indicator you are using belongs to: trend, momentum, or volume...

2. After understanding the meaning of that indicator, you need to backtest to find the suitable time frame for it. For example: MA10 works well on the M frame, MA20 works well on the W frame, so price reactions in these frames with that indicator are more reliable.

3. You should only combine 2-3 indicators and pair them correctly, for example, 1 trend indicator + 1 momentum indicator. Don't use 2 trend indicators, or 1 momentum indicator at the same time, as they will eventually conflict.

Some of those combos are: MA+MACD, Bollinger Band+RSI, MA+Stochastic...

4. You must backtest, backtest, and backtest to see how the indicator works, whether it is suitable or not, each product will have its own characteristics.

5. Indicators are programmed and use past prices (prices that have occurred) to predict the future, so you must wait for the candle to close. And waiting for the candle to close will be slower than the current price, always running 1 beat slower. The principle that must not be violated when using indicators is to “wait for the candle to close.”

You traders, when you win, write: you don't need to trust anyone, just self-deceive and you will learn from experience. When not trading, you are indifferent, rarely showing fear that others will criticize you later, afraid of exposing your weaknesses. When losing, you all rush to find good articles or news to reinforce your argument and hope, and feel uncomfortable with things that contradict that argument. I think, when you are not skilled yet, you should open your heart, close your ego, and ask more, whatever you do not understand, just ask.
