Misreable first trade

Date: 4/9/07
Symbol: DD
Entry: 49.84 (Stop Loss 48.19, Target 51.50)
Exit 48.78
Grade: F!

Okay, so this was my first trade, and everything that could go wrong went wrong:
1) I wanted to buy at around 48.75, however the market gapped up monday morning on rumors of a DOW buyout. I bought anyways, thinking this was the move that I was about to see. Bad move...

2) Big big mistake, was damn fidelity set ATP to use margin on all my new buys after I setup margin. So accidently I bought this using margin. That won't happen again, it was a simple change in the software to make CASH the default.

3) Entry was made because of MACD price divergence, buying value below 20 day EMA. DD had been in a rather tight MA channel (probably too tight).

End result: I sell out early to get it off margin, after it didn't move the direction I wanted. It did hit a high a few days later of 51.41, which would have just missed my target, and now it has swung back to the down side.
