The fail rate for traders in a real trading firm is something like 50% anecdotally (i.e. 1/2 of those hired don't make past 12mo mark)

The fail rate for retail traders without the professional environment backing them would be >95%.

That is to say the best thing you could do to increase the probability of your success is to get in the door at a reputable place.

https://robotwealth.com/ is probably the only source of information for a retail trader that I'd recommend. It's still far inferior to actually getting a seat at a real shop.

There's plenty of work for programmers in trading companies too - much better job stability than for traders.
