You should avoid using technical indicators. Because these indicators are not created with the purpose of making you profit, these indicators are just there to create liquidity.
If you think like everyone else or if you follow everything you see on the internet you will always lose. Because the movements that the market makes are not random. The market follows liquidity (follow the mass to trap the mass)
Experience will determine the level of success of a person in trading but I believe more that trading will have a time when someone gets a loss.
That applies at all times as you said and there are times when we lose and others win or vice versa.
But traders must understand how to recover losses in previous trades so that we are not trapped in continuous losses.
The only thing that can help recover losses is by understanding trading well so that knowledge combined with experience will provide an idea of how to recover.
But it must be remembered that trading only a few people succeed because if there is no knowledge or experience it is impossible for them to achieve success.
