After a transaction, no matter what the profit or loss is, from the mentality, everything should be cleared.
The profit or loss of this time should not affect the next transaction.
Today's profit or loss should not affect tomorrow's transaction. If you can't get out of the last failure, you may fall into a vicious cycle and there is no way back.
And when you are doing well, you must also stabilize your mentality and don't let your heart float, because when people float, they are prone to make major mistakes.
