How to Calculate TON Futures Position Size?

Understanding TON Futures Contract Specifications

1. Each TON futures contract on Bybit is quoted in USDT and settled in TON tokens.

2. The contract multiplier is fixed at 1 TON per contract, meaning one contract represents exactly one TON token.

3. Minimum order size is 1 contract, with no fractional contracts permitted for standard trading accounts.

4. Tick size is set to 0.0001 USDT, ensuring granular price movement tracking across volatile market conditions.

5. Initial margin requirement varies dynamically based on leverage tier selected, ranging from 1% at 100x to 10% at 10x leverage.

Core Inputs for Position Sizing Calculation

1. Account equity must be expressed in USDT and verified before any position calculation begins.

2. Selected leverage level directly determines the margin percentage applied to the notional value of the position.

3. Entry price in USDT per TON serves as the baseline for computing both margin usage and liquidation thresholds.

4. Risk tolerance percentage—typically defined as the portion of equity allocated per trade—is entered as a decimal (e.g., 0.02 for 2%).

5. Stop-loss distance in USDT per TON defines the absolute price difference between entry and stop level, anchoring risk exposure.

Manual Position Size Computation Steps

1. Compute dollar-denominated risk amount: Account Equity × Risk Tolerance.

2. Derive tick-value-based risk per contract: Stop-Loss Distance × Contract Multiplier.

3. Divide dollar risk by risk per contract to obtain maximum allowable contracts: Dollar Risk ÷ Risk Per Contract.

4. Apply margin constraint: Floor(Usable Margin ÷ (Entry Price × Contract Multiplier × (1 ÷ Leverage))).

5. Final position size equals the lower value between step 3 and step 4, rounded down to nearest integer.

Impact of Funding Rate on Open Position Value

1. Funding payments occur every 8 hours and are calculated based on the difference between mark price and index price.

2. Positive funding rates transfer USDT from longs to shorts; negative rates reverse the flow.

3. Accumulated funding impacts effective equity used for margin maintenance without altering nominal position size.

4. During high volatility, funding rate spikes may trigger automatic margin calls if unrealized PnL erodes available margin below maintenance threshold.

5. Mark price divergence exceeding 0.5% from index price activates tighter funding intervals on select exchanges including OKX and Bitget.

Common Questions and Direct Answers

Q1: Does contract multiplier change during TON halving events?No. TON futures contracts maintain a constant 1 TON per contract multiplier regardless of network-level tokenomics adjustments.

Q2: Can I use cross-margin mode when calculating position size for TON perpetuals?Yes. Cross-margin mode allows full account equity to back positions, but position sizing logic remains identical—only margin source differs.

Q3: Is the tick size uniform across all TON futures expiry dates?Yes. All listed TON futures—including quarterly, bi-weekly, and perpetuals—share the same 0.0001 USDT tick size.

Q4: How does slippage affect position size accuracy during rapid price moves?Slippage alters actual fill price versus intended entry, thereby shifting realized margin usage and risk exposure post-execution without changing pre-trade size computation.
