Many people have a huge misunderstanding about rolling positions. Most margin calls happen because traders keep adding to losing positions as the price drops, deepening the loss each time, until the final margin call ends the game. True experts in rolling positions follow a different logic—profit rolls into profit, principal is never at risk, floating gains are used to add positions, letting the earned money run on its own.

**How to operate specifically? Follow three steps:**

**Step 1: Test the waters with a small position, control the cost of trial and error**
Start with a 400U position, leverage of 3-5x, and always set a stop-loss. This step is about testing the direction with minimal cost—see if it’s right, can you afford the loss or not.

**Step 2: Use floating profits to add positions**
When your position’s profit reaches 50%, for example, earning 200U on a 400U position, directly use that 200U to add to your position. Keep leverage consistent. The key? Risks are borne by floating gains; the principal stays on the sidelines watching, very safe.

**Step 3: When profits approach the size of the principal, take protective measures**
Take some profits out or hedge, then continue chasing the trend with the remaining position, dynamically adjusting take-profit points. The result? The principal remains silent, while profits grow through compound interest.

**Why do most people get margin called?** Actually, the wrong direction isn’t the main reason; the problem lies in chaotic position sizes and rhythm. Blindly holding positions, frequently adding to losing trades, emotional leverage—these all eat into the principal. The essence of rolling positions is to use profits to expand gains, not to gamble with the principal.

**Four ironclad rules must be followed:**
1. Never add to risky positions with the principal
2. Add to positions with floating profits only after market confirmation, don’t rush
3. Lock in or hedge profits once they reach a certain level
4. Be resolute with stop-losses, don’t hold onto losing positions

Market conditions change, but the strategic framework must stay the same. Currently, market volatility is high, which is exactly the golden period for this rolling position strategy. Strictly follow this logic, and your account curve will steadily rise, completely breaking free from margin call cycles. Dream less, discipline more, let profits run, and give the principal a rest.
