A good, volatile day of trading, especially on crude oil

Thanks to crude oil's incredible volatility, today was one of my best trading days in about a month and a half. It is difficult to explain why there was so much volatility on the markets but, in general, for a daytrader/scalper like me, it is generally very profitable to trade under that kind of market condition. I had problems only with natgas and the euro, but for the same volatility reason. So this can be a factor both ways in your trading  if you see what I mean. In short, a very good day for me. Net result for today: +$606 trading 1 contract (commissions included). Details below.
