"I realized that I've learned how to extract money from the market trading a tiny set of stocks. I call them my "pet stocks" because I could tell you without looking what their intraday, 1-week, 1-month and 52-week S/R levels are, and how they react to lower highs and higher lows, how they react to the 20-bar EMA, how they break out, and so on."
For NoDoji, I would ask why do want to trade anything other than your pet stocks if you can routinely extract money from them? Are you looking for leverage? I will tell you there are so many more pitfalls in futures than in stocks (reports, fast markets, getting filled or lack thereof in fast markets, sudden global developments, more noise, etc) that compared to futures, stocks are a breeze. If you want leverage, trade your entire 4x retail account and amp up. If you want more then find a good prop shop offering 10x-100x leverage to good traders. If you can routinely extract money from these stocks why go anywhere else?
The grass isn't always greener IMHO. It would be a shame to lose money finding that out esp with what you have already in stocks (mentors, experience, etc.). But if your sim account is doing well then maybe you're already there. Please be cautious. Best wishes.
