Contract trading anti-liquidation (anti-explosion) practices;

After years of deep work in contracts, I’ve summarized a quantitative risk-control system to reduce the probability of liquidation from the root cause.

1. Leverage and risk control
Actual risk = leverage × position size. High leverage doesn’t equal high risk—the key is keeping positions light. Control total exposure and avoid going all-in on a gamble.
2. Per-trade loss limit
78% of liquidations come from stubbornly holding through unrealized losses. You must set hard rules: a single-trade loss must not exceed 2% of principal; once triggered, cut the loss—no exceptions.
3. Position sizing formula
Before opening a position, you must calculate it; maximum position = (principal × 2%) ÷ (stop-loss ratio × leverage).
For example, with $50k principal, 10× leverage, 10% stop-loss, the position size per trade is about $1,000.
4. Staged take-profit
When profit reaches 20%, reduce position by 1/3; when profit reaches 50%, reduce by another 1/3. Track and take profit on the remaining position using a 5-day moving average to avoid giving back gains.
5. Hedge extreme risks
Allocate 1% of principal to buy put options to hedge black-swan events and reduce systematic risk shocks.

Profit logic; expected return = (win rate × average profit) − (loss rate × average loss).
Under a single-trade loss of 2% and a profit structure of 20%, even if the win rate is 34%, it can still have positive expectancy in the long run.
Trading’s essence is not prediction but risk control—surviving is what enables compounding.
