But it’s not in one step, it’s in 40-50 steps innit?)Assuming you have a trading strategy available to master, you need to practice it very carefully and keep detailed records. Do this on a demo account for at least 40 or 50 trades. If it's not profitable, you either need to take what you've learned, make modifications, and test it again or else dump it and seek a different strategy. If it is profitable, the try it live on a very small account and see how it holds up for another 40 or 50 trades.
This is indeed a good approach. Have you ever tried copy trading?In my opinion, it's a challenging thing to master you trading strategy in one step.
I'm used to testing all my strategies preliminary on the demo account, at least for a while. I must be convinced of at least minor efficiency, thus I'll have a vision what to improve further on.
If the strategy is good enough and it passes through my testing, then I apply it on the real account and try to trade it, but, unfortunately, maybe lack of experience plays a big role, but I really can't stick to only one strategy. I'm forced to devise new over and over again.
