I agree completely. My equity curve looks the same in every time frame. I have a good streak of 5 weeks or so of solid wins, then i start taking larger positions, my profits zoom up and i do amazing, then i start to trade poorly, and i have period of 2 weeks where i basically break even, but with huge up and huge down days and lots of account volatility, then i have one final unreal trade that makes like 20% for my account, after that, I usually don't have a winning day for like 2 weeks, and I loose about 2/3 of what I made on that one great day before I start trading rationally again.
