In case you enter a short position at point A, but the price goes up and incurs losses at the levels:

B: -100%

C: -200%

E: -300%

this is a very dangerous situation in futures trading (Btc, eth, bnb, sol...) especially with leverage. Below are some handling strategies to minimize or avoid the risk of "burning" your account:

1. Discipline in cutting losses

Determine the stop-loss point in advance (e.g., -50% or -100%) and cut without hesitation.

Cutting early will help you preserve capital to re-enter at a more reasonable position.

2. Controlled loss averaging + Averaging down (Martingale/Scale-in)

If you have a clear plan and strong enough capital, you can:

Short more at point C (when the price goes higher) to improve your average price.

However: This strategy is extremely risky if you do not carefully calculate your capital and stop-out levels.

Not recommended if you do not have very good capital management experience.

3. Hedging (insurance for positions)

Open a long position with the same volume at the loss point (e.g., at C or D).

When the price continues to rise, the long position will offset the losses from the short position.

Then you can wait for the price to peak before closing the long and keeping the short (if you expect the price to drop afterward).

4. Reversal strategy

Recognize that the trend is no longer appropriate (the price breaks resistance, strong volume...) → close the short and open a long at point C or D.

At this point, you accept a small loss, but change your position according to the actual trend to recover.

*** Suggested safest approach:

Enter small positions, divide capital into many parts (do not all-in at A).

Clearly determine stop-loss.

Do not hold losses greater than 200-300% without a strong average price strategy.

Limit the use of high leverage when going long or short against the trend.
