Hi Don't Know
I can only suggest what I did about 5 years ago and demo trade until you find consistency with your chosen strategy. Write down every single trade especially the reason as to why you took it and ensure you write down the outcome, whether it was a winner or a loser. it is also important to write down the reason for the outcome, if it was a loss, write down why. At regular intervals, weekly if daytrading, monthly for higher timeframes, review your trading diary and write down the positive and negative observations regarding your trades as these will then form the basis of your strategy moving forward. Repeat this exercise until you become consistently profitable. Doing this will show you where you are going wrong as well as right and give you confidence that the things you are doing right will become part of the way you trade and the things you are doing wrong will hopefully be abandoned and avoided in the future.
This necessitates that you do not slavishly follow someone ELSE's system, looking to someone else for confirmation that a trade ought to be taken. Avoid threads like potential set ups for example as the originators of this system were recently 'asked to leave' a prop firm because they couldn't make it 😆 Why else would you 'leave' a trading firm? This is LAZY trading and shows a not only a lack of skill, but a lack of confidence in one's own abilities which is even more important than skill IMO. Avoid at all costs.
I understand that you are a newbie and the above seems like a lot of hard work but like everything in life, in order to be successful, you need to put in the hours. You may have lost your confidence, but the best way to build you own confidence is to develop you own system with patience and endeavour.
I hope this helps
