I know everyone is saying, "Get disciplined," etc. I think in 2013 I would have said the same thing... but in my experience it's very difficult to close that terminal when you're up. This has worked for me. When I've had a great morning, and made, say 3% on 100k, or $3000, I scale it way back and start trading with just 20k. I'm not proud of this; I suppose I should have the discipline to call it a day.
Ken: You have clearly defined patterns as a trader which from a third party viewpoint are easy to see -- may not be so easy to see yourself.
Sounds like the signals you're getting later in the day are crap,but you're still taking the trade anyway. Wait for the good set-ups.You need to be like a batter in baseball and wait for your pitch. Stop swinging at stuff in the dirt and a foot outside the strike zone.
Trading is an addiction. If you're satisfied with your AM results, switch off your PC and find something else to do. Once you have, you will feel like AM trading is plenty enough for you.
