Item | Adjustment |
Position Size (Cont) | Post-adjustment size = Pre-adjustment size × Adjustment ratio |
Avg. Entry Price | Post-adjustment avg. price = Pre-adjustment fair price / Adjustment ratio |
Margin Mode | No change |
Unrealized PNL | Unrealized PNL will be settled into realized PNL and credited to your account balance during the adjustment window. |
Position Value, Position Direction, Account Equity | No change |
Open Orders | Canceled |
Trading Bots & Strategy Orders | Will be terminated and will not resume automatically. Users will need to recreate them after trading resumes. |
Example: Suppose you hold 100-contract long position in IBIDENUSDT Stock Futures before the adjustment, with an average entry price of 90 USDT. The fair price at the time of adjustment is 60 USDT. Your account equity before unrealized PNL is 100,000 USDT.
Item | Before Adjustment | After Adjustment |
Fair Price | 60 USDT | 60 / 2 ≈ 30 USDT |
Position Size | 100 Cont | 100 × 2 ≈ 200 Cont |
Avg. Entry Price | 90 USDT | 30 USDT |
Margin Mode | Isolated | Isolated |
Unrealized PNL | (60 − 90) × 100 = -3,000 USDT (displayed) | Reset to 0. The pre-adjustment unrealized loss of 1,100 USDT is settled as realized PNL. |
Position Notional Value at Entry (USDT) | 100 × 90 = 9,000 USDT | 200 × 30 = 6,000 USDT |
Position Direction | Long | Long |
Account Equity | 100,000 + (-3,000) = 97,000 USDT | 97,000 USDT |
Open Orders | Yes | Canceled |
Trading Bots & Strategy Orders | Yes | Will be terminated and will not resume automatically. Users will need to recreate them after trading resumes. |
