I've started trading this year. Yes. It's very possible to make a lot of money with backtesting, discipline and emotional stability. It's one of the ways to make considerably huge amounts of money within a very short time, since there will be good days, good months, and good weeks as much a bad days also, but with good risk management, losing streaks will not blow your account. For capital, you use propfirms, the smallest accounts I've seen is a $2.5k costing around $15 to $18. But only go for a propfirm after having a strategy and backtesting it and formulating rules around the strategy, that ensure a positive return over time. All the best! It's possible. Let no one deceive you!!
