I like Waynes idea of putting information on a chart. Here is an example of two slides I have put together for my trades. I use to do them on graph paper and tape them into something of a scrapbook. These two slides are in powerpoint. The categories on the second slide I am putting into a spreadsheet. That way I can sort on a number of categories (formation, profit or loss, entry, etc...) to see what is working and what is not working for me.

I XX.XX'ed out the numbers except the profit objective that turned into a loss. Oh what could have been.

The trade here I made, and lost money on only to see it go in my direction. Pisses me off, but that is trading.

I gleamed this from reading many books, but the one I remember was Trading is a Business by Joe Ross. Hopes this gives you some ideas.
