I did not become a liquid in the last sharp decline and even made money by taking advantage of the decline.

If the futures positions you open are larger than your fund, try to catch them at the bottom if possible, otherwise it is inevitable that you will suffer serious losses in sharp movements.

The long-term position I opened can easily remain open for 10 years and has no liquidity risk.

Since I add after sharp declines, I do not have to wait long.
