I have been a Challenge student for right at a year now. I have NOT made very many trades at all yet. I have purely been focusing on watching his videos and watching the others that I have bought. It has taken me personally this long to "Be Ready" to trade and use my real money. I did use Tims watch list and Kroyrunners DVD/ Watch list to help me pick my buy and sell price for the stock. Even though I did not get my .10-.30 per share, I did follow Tims rules and Kroyrunners rules and education on being patient, following the rules we have in place, watching the ticker, and Level 2 charts to make the decision that I did on this execution. 

Bottom line is I can not wait to be on top of my game and make big money. However, I am focusing making this what I want to do for a living so I can have the freedoms my wife and I have wanted for years.

So my point in the entire message is, $STUDY, ask questions, buy DVD's. And when you are ready, step into the market and practice what you have learned.

As far as bid size, bid what is comfortable for you to loose. If you have rules, you practice, and follow them. It will help you get past the fear of trading.
