i daytrade for a few reasons. one reason is because i do not like losing and we all have losers in trading. Another reason is because it is just plain crazy to try and figure where the players will take the mkts within a few weeks or months. The macro picture these days are controlled by "world" money flows, events, rates, gov's etc, etc. The "HUGE size of the hedgies and the country soverign funds etc have enough power to go up or down dozens of points. how can one trade stuff like that while being a small fish? The world of stocks or commodities was a lot easier when the USA as the world dominate economic power. those days are over and they are over big time. We adjust or we wither on the vine as traders.
Many say backtest. Backtest to what? What goldman did and now are doing the opposite. ..
