Long and short hedging has only one purpose: to save your trapped long positions during critical moments and lower the liquidation of your long positions, not for profit. The short position should generally be 1/4 lower than the long position, as it is only a supplementary position. This way, when the market improves, you can minimize losses and even have a slight profit when the market pulls back.
Additionally, there is another way to break the trapped position. If the market suddenly reverses and you get trapped, you should decisively make a decision: first reduce your position by 25%. For example, if you reduce your long position by 25%, you should simultaneously open a short position of 25%. When the market pulls back, take profit downwards. For instance, if your long position is down by 3 points, after reducing the position by 25%, open a short position of 25%. If the price drops by more than 3 points from the current price, you can recover the floating loss from the reduced position. This can help you get out of the trapped position, and occasionally, you can profit from both sides. However, when the position is not so dangerous, hedging should be used with caution; do not touch it unless in a crisis, as beginners are prone to being trapped on both sides.
