What Is TON Futures Liquidation Price Formula?

TON Futures Liquidation Mechanism

1. Liquidation in TON futures occurs when a trader’s margin balance falls below the maintenance margin requirement set by the exchange.

2. The system triggers forced liquidation automatically once the margin ratio drops to or below 100%, calculated as (Available Margin / Required Margin) × 100%.

3. Liquidation price is not fixed—it dynamically shifts with market movement, position size, leverage level, and funding rate adjustments.

4. Exchanges operating TON perpetual contracts apply mark price—not last traded price—to prevent manipulation-driven liquidations.

5. Mark price incorporates index price, funding rate decay, and decaying premium/discount over time to reflect fair value.

Core Variables in the Formula

1. Initial margin is derived from position notional value divided by selected leverage (e.g., 20× → 5% initial margin).

2. Maintenance margin percentage varies across platforms: Binance uses 0.5% for TON/USDT, Bybit applies 0.75%, and OKX sets 0.6% for standard contracts.

3. Position direction determines whether liquidation price lies above (long) or below (short) the entry price.

4. Funding rate accruals directly impact unrealized PnL and thus available margin—especially during prolonged funding surges.

5. Index price is computed as a weighted average of spot prices from at least three major TON liquidity providers, refreshed every 5 seconds.

Long Position Liquidation Price Calculation

1. For a long position: Liquidation Price = Entry Price × (1 − Initial Margin Rate) / (1 − Maintenance Margin Rate).

2. If a trader opens a long at $8.42 with 25× leverage (Initial Margin Rate = 4%), and maintenance margin is 0.55%, the theoretical liquidation price becomes $8.093.

3. This assumes zero funding fees, no partial liquidation, and static index price convergence.

4. Real-time execution accounts for slippage during rapid price drops—often pushing actual trigger point lower than formulaic output.

5. Exchange-level insurance funds may absorb minor shortfall, but full liquidation proceeds execute at auction-based prices determined by the matching engine.

Short Position Liquidation Price Calculation

1. For a short position: Liquidation Price = Entry Price × (1 + Initial Margin Rate) / (1 + Maintenance Margin Rate).

2. At entry $8.42 with 25× leverage and 0.55% maintenance, the short liquidation threshold computes to $8.762.

3. Negative funding rates over extended periods erode margin faster, pulling effective liquidation price downward even if price remains stable.

4. Tick size constraints on TON futures—typically $0.001—introduce rounding effects that shift final trigger levels by up to one tick.

5. Some platforms implement tiered maintenance margins; positions exceeding 500,000 USDT notional face 0.8% instead of base 0.55%, altering the denominator in the formula.

Frequently Asked Questions

Q1: Does leverage change the liquidation price after opening a position?Leverage itself does not retroactively alter the liquidation price once the order is filled—but changing leverage mid-position via margin adjustment recalculates the threshold based on updated initial margin.

Q2: Why do two exchanges show different liquidation prices for identical TON positions?Divergence arises from differing index price sources, funding rate calculation windows, maintenance margin tiers, and mark price smoothing algorithms—not from errors in basic arithmetic.

Q3: Can stop-loss orders prevent liquidation entirely?Stop-loss orders operate outside the margin engine; they are subject to slippage and may fill far from intended levels during volatility spikes, offering no guarantee against liquidation.

Q4: Is the liquidation price visible before order execution?Yes—trading interfaces display real-time estimated liquidation price alongside position details, updated continuously using live index and funding data feeds.
