[BAn interesting topic, too bad there has not been alot of participation [/B]
I suspect that in this case the lack of participation might be that many people don't scale in and out, and even more don't understand how/why, while others have discounted it and decided it doesn't work for them so ignore the thread...
It looks like a double edged sword. On the one hand, a good long ranging trade can benefit from adding more size, on the other hand, a long ranging trade that doesn't follow through leaves you adding size at just the point of failure so setting up a potential loss rather than taking a small profit.
There is then also the confusion element, because instead of running the trade and finding its natural conclusion, you could be looking to add, and consequently the view of what is actually happening can easily be obscured by this. Stopping in upon passing key points might be something that would work, because the break of a key point in the run will usually involve a catapult effect towards the next key (danger) point and your additional size gets picked up along the way.
Perhaps another approach might be to treat everything initially as a scalp, with smaller size, looking for the failure point and if you get lucky and it runs then add. at least that way you are not being obscured by looking for a point to add instead of being aware of the trade's failure point.
I guess there are pros and cons to any approach. It should be noted though, that if you are adding into a trade twice, you are actually running 3 different strategies simultaneously, which can also add to the confusion, and having a good understanding of exactly what you are doing is critical to the success of such an approach or losses quickly creep up on you without necessarily a realization that it is happening or how it is happening.
This also looks like the flip side of the question of taking profits/partials and then re-entering along the way for a continuation of the same run. Again something that merits discussion
Just a few disparate thoughts on the subject...
