Good point. That alternative occurred to me after I created the poll and was no longer able to change it. My apologies. Let's see if the moderators can help us here.
All else being equal, and in the long run, I think that you may have a good point. That is why I have chosen what I believe to be the least bumpy ride.
It is a function of money management really. You are using the profits from a trade going your way to add more based on an additional entry signal. On the exits, it is good to know what target lies ahead in a distance, but I trade it better when I peel some off to have a free trade if it doesn't go. I can't imagine being precise enough to take all in and all out in one go. It is a matter of preference. This, of course, is from the perspective of a scalper.
Your post makes good sense to me. What you regard as scaling in based on an "additional" (subsequent) signal, I would simply regard as a "separate" signal. However, I like to scale out for the same reason that you do. The scaling out has nothing to do with a subsequent signal, but is the result of reaching an interim profit objective. Apart from our timing, we may be doing similar things but simply describing them differently.
