Why do you say this Bob? I do far better on my daytrades than I do on my long plays these days. The volatility is great for day trading and intraday technicals are holding up particularly well of late.
Anyways, if you're going to daytrade, I suggest you pick just one or two stocks or ETF's and really get to know how they trade. Don't try to daytrade your whole portfolio and remember that daytraders are shooting for very small percentage gains... take your profit when it's there.
