A very high volatility day on the markets

What would best characterized the way markets were today is high volatility. Generally, it's a good environment for daytrader like me. But when its TOO volatile, its gets very risky to trade. The morning session was not as volatile so that's when most of my 9 trades were executed. The afternoon was wild and not suited for a conservative guy like me. Anyway, I am experienced enough now to know when to trade and when to be careful. All in all it was a good trading day with substantial profits. Results: +$489 (trading 1 contract).
