Thanks Randall for your advice.
I hear regularly from seasoned traders that day trading takes years to master. Especially when you consider that trading is mostly a solitary endeavor for most of us, and we don't automatically share our experiences. That's why I'm so thankful for the boards and the advice that can help shorten the time to mastery.
So I will be devoting more time to learning about all risks involved (sub-pennies & day trading in general), and to cater a strategy to my lifestyle. It seems that no matter how seasoned a trader may be, he will always be fighting a battle with the market. And then there is the "smart money" that controls so much of it, and the SEC and other agencies that allow so much fraud....
I guess I am a bit impatient, but I'm improving in that dept.
Trading has been in my blood, so there is no stopping for me. I'm still seeking a strategy for my personal threshold. Then,... like you said, "Make rules and follow them."
