When you lock in your 1 pt gain, have you studied the occurrences of getting another tick or two If you are up a point does the market give you another tick or two before it goes back to breakeven This alone would increase the return 25-50%
What's there to understand? Have you defined anything yet other than 1 point profit. If you are looking for someone else to tell you, without doing the testing yourself, as a few have already mentioned its not a winning strategy for ES, to try to obtain 1 point with a 1 point stop or something along those lines. If you hit 90% of the time better hope you don't take a 9 point or more loss on that 10th trade. And that's not even accounting for trading costs.
And a "reverse" and a "backfill exit BE or Exit on small loss" also. You have 15% of system, and the easy part at that. All fixable if you realize it.
For the amount of investment and the amount of risk you accept it would not cost to much to hire someone to backtest At least look at the last 10 trades and see if you could have taken an extra tick....
Here is the eMini Micro (smaller size, good for live testing) currently one point range bars blue color for up close, red for down close. Plain to see how often it flips back and forth ... forth and back.
