If you're just relying on virtual or test trading without any application of your money, you're just like playing trading in the market but you don't apply it to your own.
You can formulate some strategies that you'll be familiar with and can be your counterpart as you trade because you're getting a positive result with it.
Start with small capital, and the rest happens good based on the way you do things through market observation.
That's where it's going to start the learnings. You'll have to extract every single mistake that you do with that first try and you'll have to learn from it so that you'll apply that with your next trades and that will be part of your good trades.
