from the old fraction days to keep greed in check: the last tinnie and eighth are the MOST expensive ones when the tray with the cookies gets passed around.. grab some, it may not come around second time.
Don't let a profit go to a loss. Don't carry a loser overnight. Let your winners run and cut your losers short, but don't be afraid to ring the cash register either. Ka-chingo baby!!!
My KISS rules for any expert approach. A. Trade the slowest chart possible to pick off all trends including lateral swing moves. (5 min to 30 min intraday.) B. Wait until the market settles down at open(15min max) C. Always go in on the first bar that breaks out beyond prior bar after B occurs. D. Stay on the right side of the trend. Only reverse when the trend fails to continue. (Use trend lines and get break out of trendline) E. When trend doesn't build after reversal, continue quick reversals to stay on right side of chop or whippy market. (Use lateral trend lines to show the high and low of chop) F. When consolidation of E ends with centering of latral trend, exit and reenter on break out of the pennant and go to D. G. Use MOC. For example: Today, I did chop until 10:10 (S,L,S,L,S) and stayed in S (1020.3 reverse) till 12:00; L till 13:20; S till 16:00; L till MOC. Good Luck.
I really only have comments on some of these rules. Only rule I wanna add is for those idiots messing up trades. Stop screwing it up and start trading.
