Scaling out of Brent positions – managing risk vs. missing upside?

Been trading Brent futures for a few months now, still figuring out my optimal exit strategy. I've been scaling out of positions as they hit profit targets, which helps lock in gains, but sometimes I feel like I'm leaving too much on the table if the move extends significantly. On the flip side, I've avoided some pretty nasty pullbacks by taking partials. How do more experienced traders here balance protecting profits by scaling out versus staying in for bigger moves, particularly in a volatile market like crude? Is there a common framework or set of conditions you use to decide when to scale and when to hold tight for the full ride?
