Cheng,
Yes. I do keep records of all my transactions which includes the following:
1. Stocks/Futures
2. Reasons for buying/shorting
3. Entered price
4. No. of Shares/Lots
5. Sale of stocks/Date sold (shorts covered)/
5a. If profit, %tage profits +reason
5b. If loss, %tage losses + reason
6. Where I went wrong if there is a loss (of course if I stick to my cutting losses, its OK )
7. The profits/losses are grouped by month.
I used to have a spread sheet to track my feelings daily about the market. I found it too tedious to update on feelings cos there might be weeks/months where I don't have a single trade
Hope this helps.
Cheers,
mm
