Dude Bugscoe and Thunderdog are agreeing on something. This is a moment to be cherished. Oh ya elitist trader. In all seriousness you might increase your chances of profitability from 4% to 5%. My true advice to you is EXPERIMENT, listen to no one but yourself and prepare yourself for years of frustration.
Let me say that there is a gentleman on ET who had an active journal (until it got spammed not long ago), who as a result of a bet was limited to one monitor and all trades through Scottrade, not a day trader's top choice for speed and low cost trades that's for sure. He is up 74% this year using a very simple effective trading strategy and a 1:2 risk:reward ratio.
