Your experience is very different from mine. It took me two years to reach consistent profitability. Over the 17+ years I've been trading, I've only met a few successful traders and they all said it took them a couple of years to get to consistent positive performance.
Quote from intradaybill:
Consistently profitable traders are from day one. Those that turn profitable are scarse examples similar to those people who win the lottery - and any reference to them as examples is selection bias. You either have it or you do not. More people turn unprofitable from profitable but very few turn profitable from unprofitable.
It is like asking a great painter like Picaso, if he were alive, what was the single most important realization that put him over the top. None, he already had it. Trading profitably consistently is even more difficult than being a top painter.
