I trade stocks and futures and make my living doing it. I started trading in the middle of 2000. My years net in order from 2000 are $110,000, $365,000, $210,000, $220,000, $130,000, $110,000, ($7000), and this year to date $50,000. Trading is hard and I really couldn't teach or quantify to you what I know.
Basically I'm a tape reader. I use volume and an 20 ema on various time frames. Imo technical indicators like macd, rsi, obv are almost useless. They will always lag price. Market internals are the only "indicators" you should use.
But really the only important thing that I can stress to become a winning trader is to limit your losses. These days I have my account auto liquidate if I hit ($3000) on the day. Trading is about saving yourself from yourself. Most of the people on this board are not real traders and do not do this full time. How do I know this? I read their comments and can't believe some of the bs written on these threads.
