The essence of trading is probability

No one can probability
Achieve a 100% win rate
Every transaction is a trial and error
Using a verified system
Waiting for signals in the market
When a signal that matches your entry criteria appears
Be decisive and enter the market
Set stop loss according to the rules after entering the market.
If it's wrong, cut the loss with stop loss.
Hold firm if it's right.
Then repeatedly train
Probability and profit basically have a guarantee.
