Exiting at B/E doesnt exclude a trader from taking part in any further trades.
I like your long term trade method.
Yes but it does exclude you from your original trade. e.g. You entered a long on ABC contracts for $1 and the price moves to $2 so you move your SL to BE. I entered long on ABC contracts for $1 and the price moves to $2 so I take half my lots off. The price retraces to $1 and you get stopped out. You are not thinking about reloading your trade at the same level (why would you, you are a BE trader - your trade parameters have been modified to indicate $1 is now the level at which your trade is incorrect). I am very much thinking about reloading my trade. See the difference?
If trading is a business, then taking half off at 1:1 is how you make assets. I just simply can't see any case where moving SL to BE is the more appropriate action to take.
For the third time in one page, if you have any systematic way to show this "over 500 trades", then I request that you please do show it. Or at the very least, please explain how you quantify "moving SL to BE" over 500 trades as part of your plan.
