入场后加仓/减仓 - 你的看法？

I generally let my initial position ride if it's moving favorably, as scaling in can quickly change your average entry and risk profile. For positions moving against me, I stick to my predefined stop; partial scaling out before then can become a slippery slope, often just delaying an inevitable stop-out while tying up capital.

My take? If it's going in my favor, I usually just sit there wondering if I should have gone bigger to begin with. If it's going against me, scaling out early just sounds like a fancy way to say I'm cutting my losses before they get too embarrassing.
