This is how I used to interpret it:

Hedging positions do not seek to make a profit, only to ensure safety.

When the price drops to near the opening price of the long position, close about half of the long position to ensure the liquidation price remains within a safe range.

Then observe the trend; if it goes down, close part of the short position, and the closed position will be based on the previous profits from the long position.

If it continues to rise, then keep increasing the long position to lock in.

Repeat this step until there is a pullback or the position is reduced to a safe range.
