逐步减仓 vs. 逐步加仓：你的看法是什么？

I prefer to scale out of winning positions, mostly because I've found my conviction tends to evaporate faster than my profits if I don't. Plus, a bird in the hand, and all that jazz.

This is a great question I've been wrestling with too! I can see the logic in both, but I'm still trying to figure out if there's a general rule of thumb or if it really is just entirely dependent on the specific trade.
