Scaling into / out of WTI positions effectively?

Still getting my feet wet in the energy space, specifically with WTI. I'm comfortable with initial position sizing, but when the market gets volatile around news releases, I find myself struggling with how to scale in or out without just widening my average into a losing trade or cutting winners too short. For those actively trading WTI, what's your general approach or any particular method you favor for managing position size adjustments post-entry, especially during periods of high chop?
