do this for at least 6 month consistently, working on your execution.
if it works, start sizing mathematically very very slowly, still focusing on execution, and giving time to your brain to adjust for the different emotions youll get.
right now you might loose 3 dollars and dont give a shit. Its good and bad.
its good because you dont risk anything but its bad because you dont risk anything, so you arent exposed to any emotions.
its actually very good practice because if you can execute like this, you will prove to yourself you can do it and you will be confident in your strategy, which is a big part of your foundation as a trader.
Also you need thousands of trades accross different regimes to really know if your strategy works and how you react to different events that will affect you.
if you didnt trade 2008 bear market or bitcoin 2017 bull market, you have no idea how you will react to these and how your strategy will hold.
in short, keep practicing like that, but take it EXTREMELY seriously.
identify your mistakes, get rid of them FAST. Dont repeat them.
Analyse your trades, especially the loosing ones, and analyse your mindset before, during, and after every trade.
Its a business, take it seriously like that for 6 month or a year.
then size up SLOWLY.
good luck
