i believe scenario is valid. How he did it, appears about right. This kind of gains relative to risk 10:1 or more are possible after one masters from scalping to swing trading to major macro calls, to charting to psychology & reading fundamentals. Takes time to get there. No shortcuts.
relax noone can be sure whether number are legit. But how he described action it is valid scenario. Not that I have been thru yet. But i am working on it with longer term calls. In this market you can have bets 10:1 as market runny. Start with 1k risk, you win 10k. Reinvest in next trade and win you have 100k, reinvest in next trade and you have 1m he was short and had serious profits from day before. Than it takes courage what he did but he was on the roll and probability of win high.
Great job... to protect it.. take 1/2 out.. consider backing a trader like myself with a token amount, i.e diversify. PS: Whether it fake or not.. good goal to work toward.
