I have been averaging down mostly so that i can enter the trade early...if it moves in my direction quickly, then great and entering early means i captured a gain that i may have missed if i had waited for a more "optimal" entry.
If it moves against me, then i scale in and as long as it turns in my direction before my loss max is hit, then I make even more money because my size is bigger!
When it continues to move against me, of course, my losses are a little bigger. But, my win percentage has easily been making up for it.
Sounds similar to what you were doing in sim!
Anyway, to answer your question, I am going to stop averaging down because i want to prove and ensure i can trade consistently profitably without averaging down. Thats the simple answer.
I do not subscribe to the theory, as it seems everyone else here does, that averaging down is inherently wrong/losing/etc.
But, i'd like to be able to fundamentally trade more precisely and consistently profitably, and then maybe come back and dabble with averaging.
Also, i know from experience that averaging works A LOT LESS WELL in more volatile and heavily trending markets. I believe the market over the last 2-3 months has simply been ideal for averaging and mean reversion. Friday was a great example of a day where averaging down had the potential to be painful, for example (even though i didnt do it on Friday).
Also, and lastly, averaging down is addictive. It requires more discipline to stop when you are supposed to and not average further down. I've been doing well on this aspect of it over the past couple of months, but i have burned myself previously by averaging down too many times to too big a size.
