Short and Long Targets.

This midpoint is good for being half in, half out. If it drops into support you can rebuy and lower your Base price, if it runs up into resistance it is easier to liquidate a position and cover short equity.

For my I've sold half of my 150 coin(32 of equity) position here. If it drops near 600 I rebuy. If it pumps near 630 I close my long and short cover my 32 coins of equity.
