It sounds like you dont have a plan that you believe in with clear entry and exit criteria…
Here are some suggestions from me;
Pick one set up and only trade that set up. Master it before moving on to the next one or do the opposite if the failure rate is so high. The point is, pick one set up that you can execute consistently. From here, your approach will evolve.
Try and codify your plan. Create a set of simple rules for entry, exit and money management. Try to be as precise as you can when creating your rules. Remove any ambiguity. read your rules often and before you start any trading session.
You are too outcome dependent. Detach yourself from the outcome. Easier said than done but if you start with the above suggestions, then over time, you will start to have faith in your approach. Reducing your lot size might help.
Trade the higher time frames. Execute your trade then walk away. This includes stop loss and profit targets. I recommend the 1H time frame and above. On these time frames, it will take at least one hour for the paint for one candle to dry. You are too close to the noise when trading the 5m chart. Some might say that you are trading randomness on this time frame. Day trading is very, very difficult, if trading was not difficult enough. Dont make it harder than it is. Up the time frame and take a step back.
Trading is a difficult skill to master, it can take a lot of time and requires practice. This is also a journey of self discovery. You might just have to accept that you are learning things about yourself and your trading and it is going to take time to iron out any self defeating habits.
