I agree in theory but in practice I'm not that precise - I either get into the trend because its a trend or stay out of the trend because its not actually a trend anyway. I do pay attention to two types of TA warning signals though that might keep me out of a good trend - one is when my chart for XXX/YYY says buy but all the other XXX/ pairs say sell - the other is if price in a trend is intra-day testing the prior swing high/low.
precision is not possible because if the swing up, in a high probability move is 'powerful' ,then one more swing up, is high probability. generally if the move is weak and a trade signal triggers, i generally take that signal
Sell into strength especially, if you are trading short term. Whatever profits you have, you will be selling at favorable prices as the stock price continues to go up. Contrast that with waiting till the stock comes down on a pullback or worst has a deep correction---most if not all your profits could be gone. Forget trying to get out at the absolute top. Pretty hard to do.
Stop losses are always, always determined before or latest on entry. Then current price action should determine where trailing adjustable profit exits should rest. Otherwise just "put your money or red or black".
But it has nothing to do with process, only position size. Unless you are suggesting that the trader is trying to have a return of a fixed amount using different account sizes. Then the returns would have to be greater with the smaller account. If you are risking 1% of your capital per trade the only difference is the position size. Unless of course you're making many trades and the commission eat into your returns.
Don't position size is part of the process? 1% of 10K vs 1% of 100K would enable vastly different sell strategy.
1/3rd, 1/3rd, 1/3rd as I said based on price action. Either it confirms what I believe or it doesn't.
