The advice I am going to give is that you should look at the mistakes you made before.
You should try to understand what made you lose. You have had such experience and you will have to use that to your advantage.

When you have understood what caused you to lose, then you start looking for the solution and how to do things better next time so you don’t lose money again, and even if you’re going to lose, you should at least be able to reduce the loss. Study everything that needs to be studied and develop your strategies that will help you make more profit in the market.
