End of day method of trading

Hi Pat, first of all, thanks for your service and your passion for education.

I have watched most of the videos and answers regarding end of day trading; but, I have a few questions, or clarifications regarding how to use your service.
I have traded for three years with modest result (with a mechanical system), so I am looking for an edge.

These are my "constraints":

1. I can only trade based on end of day data (I work all day and only have time at night to review the positions and put the orders).
2. I agree to target 5 positions, starting with half the position (50%) and adding two other positions (30% and 20%) at regular intervals; but, on pullbacks or congestion areas. This because I don't feel comfortable adding on 2.5% and 5% from initial buy point; and also, at least for me, it's difficult to put the three orders for each one of the stocks that I could possible buy.
3. One of the problems that I have trading with end of day data on break outs is that I don't know how to select the stocks in order to put the buy stop order.

So my question is: How can I better use your service given these constraints? Is it possible?

Best regards,

Marcelo
