Yes, in the forex markets I've been told it's 1-2% per month and 3-5% for very exceptional traders, 300% returns is unheard of, if you made 10% per month you are one of the very few. I do know a fund that pays out 1% per day on a $1k investment as a bond, 0.5% for $10k and something like 0.25% for $100k, but they invest with professional traders who generate mind boggling returns, but also use $multi-million software to do it, which I'm sure you don't have. No, you will not make that any time soon trading, long term trading over months or years is possible but you have to pick the highs and lows, easier said than done.
