Scaling into commodity futures – how do you handle it without getting chopped?

Hey everyone, been lurking for a bit and learning a ton. Really appreciate the candid discussions here. I'm trying to get my head around scaling into positions, particularly in commodity futures, and feel like I'm missing something fundamental.

I've paper-traded $WTI and some agricultural futures with a few successful scale-ins on longer trends, but when the market gets choppy, my attempts to add to winners or re-enter after taking partial profits just get eaten alive by reversals. It feels like I'm either adding too soon into a consolidation that breaks the wrong way, or my re-entry is at a worse price right before another leg down. I understand the concept of using logical levels, but the practical application in a live, moving market is a different beast. For those of you successfully scaling into commodity positions, especially with their inherent volatility, what's your general approach to managing entries and sizing after your initial position?
