Ain't good at trading and I didn't try this strategy you've said, so my advice is don't forget to include in your plan the stop-loss which is very helpful when you experience a massive loss. You should have this good technical analysis based on your stop-loss levels on key support or resistance levels, trend lines, or other technical indicators that are relevant to your trading strategy.
If i trade but now due to financial problems i can't trade so much and don't have enough funds..
IMO, it's important to prioritize your financial well-being over trading, especially if you're facing financial problems and don't have enough funds.
My advice is to put an amount that you can afford to lose.
