Formulas

This document defines the trading rules and calculation methodology for futures contracts on the exchange1 Global platform. All contracts on this platform are margined, priced and settled in USDT. It covers margin modes, order entry, fees, funding and the liquidation logic applied to every position.

Applies to all USDT-margined perpetual and futures contracts on the Global platform.
Covers both Cross and Isolated margin modes.
Defines order-entry cost checks, fee and funding calculations, and liquidation pricing.
All Monetary figures are shown in USDT with the INR equivalent alongside, converted at the INR Rate.

Note: On the Global platform there is no currency conversion: balances, margin, fees, P&L and costs are all denominated in USDT.

2. Key Concepts & Account Parameters

The following parameters drive every calculation in this document. Users should understand each before placing an order.

Parameter	Meaning
Available Balance	Free margin in the account available to open new positions.
Leverage	Multiplier applied to margin to determine position size.
Mark Price	Fair price used for P&L and liquidation, independent of last trade.
Opening / Average Price	Entry price of the position.
Contract Direction	+1 for Long, −1 for Short.
Contract Unit / Face Value	Underlying amount represented by one contract.
Quantity	Number of contracts (or token quantity) held.
Fee Rate	Trading commission rate applied to notional value.
Risk Ratio	Maintenance threshold; liquidation triggers when the margin ratio falls below it

3. Margin Modes

3.1 Cross Margin

In Cross margin mode the entire available account balance backs all open positions. Profit on one position can offset loss on another, and liquidation is assessed at the account level.

Cross Liquidation Condition


        (Available Balance + (Total Floating P&L − Total Required Commission Fees))
        ÷ Total Margin Used for Open Positions < Risk Ratio

Cross Risk Ratio


        Cross Risk Ratio (Account Balance + Total Floating P&L − Total Commission Fees) ÷ Total Used Margin × 100%

3.2 Isolated Margin

In Isolated margin mode each position is backed only by the margin allocated to it. A loss is capped at that position's margin and cannot draw on the rest of the account.

Isolated Liquidation Condition


        (Position Margin + Unrealized P&L − Estimated Closing Fees) ÷ Position Margin < Risk Ratio

Isolated Risk Ratio

 (Margin + Floating P&L − Estimated Closing Fee) ÷ Margin

4. Order Entry & Cost Calculation

When a user submits an order, the platform validates affordability by computing the margin, fees and total cost of the position, then the maximum number of contracts the available balance can support.

4.1 Available Margin After Fee Reservation

Available Margin = Available Balance ÷ (1 + Leverage × Fee Rate)

4.2 Position Value


        Contract Quantity × Mark Price  (USDT)

4.3 Cost & Fees

Cost


        Cost = (Face Value × Quantity × Opening Price ÷ Leverage) × (1 + Fee Rate × Leverage)  (USDT)

Fee


        Opening Price × Quantity × Unit Conversion × Fee Rate  (USDT)

4.4 Maximum Contracts

Max Contracts = ROUNDDOWN( Available Balance ÷ Total Cost per Contract )

4.5 Worked Example

Using the Global order-entry parameters: Available Margin 8.85 USDT, Leverage 72×, Fee Rate 0.05%, Price 60,000, Size 0.001 per contract.

Step	Value (USDT)
Available margin after fee reserve = 8.85 ÷ (1 + 72 × 0.0005)	8.5425
Position size = 60,000 × 0.001 × 1	60.00
Cost per contract = (0.001 × 60,000 ÷ 72) × (1 + 0.0005 × 72)	0.8633
Fee = 0.001 × 60,000 × 0.0005	0.030
Total cost per contract	0.8933
Max contracts = ROUNDDOWN(8.85 ÷ total cost)	9
Resulting size = 9 × 0.001	0.009

5. Complete Calculation Formula Reference

The full set of platform formulas is listed below for reference. All monetary values are expressed in USDT.

1. Cross Margin Liquidation Condition


        (Available Balance + (Total Floating P&L − Total Required Commission Fees)) ÷ Total Margin Used for Open Positions < Risk Ratio

Note: Condition is unit-neutral (a ratio). All balances are evaluated in USDT; the INR platform displays the same balances multiplied by the INR Rate, but the ratio itself is unchanged.

2. Isolated Margin Liquidation Condition


        (Position Margin + Unrealized P&L − Estimated Closing Fees) ÷ Position Margin < Risk Ratio

Note: Evaluated per position. Ratio is currency-neutral.

3. Cross Margin Liquidation Price


        Liq Price = Mark Price − Contract Direction × (Available Balance + All Position Floating P&L − All Opening Fees − All Position Margin × Risk Ratio) ÷ (|Contract Quantity Difference| × Contract Face Value)

Note: Position Floating P&L = (Mark − Open) × Qty × Direction × Face Value. Opening Fee = Qty × Open Price × Face Value × Fee Rate. On the INR platform, balances supplied in INR are divided by the INR Rate to return to contract (USDT) terms before solving for price.

4.Cross Margin Risk Ratio


        (Account Balance + Total Floating P&L − Total Commission Fees) ÷ Total Used Margin × 100%

5.Isolated Margin Risk Ratio


        (Margin + Floating P&L − Estimated Closing Fee) ÷ Margin

6. Commission (Opening) Fee


        Margin × Leverage × Commission Rate  (USDT)

7. Overnight Fee


        Overnight Fee = Margin × Overnight Rate ÷ Leverage  (USDT)

8. Funding Fee


        Position Value × Funding Rate  (USDT)

9. Position Value


        Contract Quantity × Mark Price  (USDT)

10. Used Margin


        Used Margin = Quantity × Contract Unit × Opening Price ÷ Leverage  (USDT)

11. Contract Quantity


        Quantity = Margin × Leverage ÷ (Contract Unit × Opening Price)

Note: Quantity is a contract count and is identical on both platforms.

12. Unrealized (Floating) P&L


        Floating P&L = (Mark Price − Average Opening Price) × Token Quantity × Contract Direction × Contract Face Value  (USDT)

13. Cost


        Cost = (Face Value × Quantity × Opening Price ÷ Leverage) × (1 + Fee Rate × Leverage)  (USDT)

14. Closing P&L Percentage


        Profit/Loss Ratio = Floating P&L ÷ Margin × 100%

Note: A percentage; identical on both platforms.

15. Fee (Maker/Taker)


        Fee = Opening Price × Quantity × Unit Conversion × Fee Rate  (USDT)

16. Estimated Closing Fee


        Estimated Closing Fee = Fee Rate × Order Quantity × Contract Face Value × Estimated Execution Price   (or: Leverage × Margin × Fee Rate)  (USDT)

17. Realized P&L Reconciliation


        Realized P&L + Closing Fee = Closing P&L (in App)

Note: Reconciliation identity; holds in whichever currency the figures are expressed, provided both sides use the same currency.

18. Isolated Margin Liquidation Price


        Liq Price = ((0.1 × Position Margin − Position Margin + Estimated Closing Fee) ÷ (Quantity × Face Value × Contract Direction)) + Opening Price

Note: The INR form (taken from the Isolated worked sheet) divides the position margin by the INR Rate to convert the margin back into contract terms before solving for the liquidation price. 0.1 is the maintenance (risk) ratio.

19. Isolated Margin Risk Ratio


        (Margin + Floating P&L − Estimated Closing Fee) ÷ Margin

20. Realized P&L


        Realized P&L = (Closing Price − Opening Price) × Base Size × Direction  (USDT)

6. Liquidation in Detail

6.1 Cross Margin Liquidation Price


        Liq Price = Mark Price − Contract Direction × (Available Balance + All Position Floating P&L − All Opening Fees − All Position Margin × Risk Ratio) ÷ (|Contract Quantity Difference| × Contract Face Value)

Where: Position Floating P&L = (Mark Price − Open Price) × Quantity × Direction × Face Value; and Opening Fee = Quantity × Open Price × Face Value × Fee Rate.

Worked example — Cross

BTCUSDT long, 1 contract of size 0.001, entry 67,070, mark 67,200.3, leverage 75×, available 16.85 USDT, risk ratio 10%.

Parameter	Value
Symbol / Direction	BTCUSDT / Long (+1)
Open Price	67,070
Mark Price	67,200.3
Leverage	75×
Open / Close Fee Rate	0.01% / 0.03%
Risk Ratio	10%
Cross Liquidation Price (USDT)	50,438.4

6.2 Isolated Margin Liquidation Price


        Liq Price = ((0.1 × Position Margin − Position Margin + Estimated Closing Fee) ÷ (Quantity × Face Value × Contract Direction)) + Opening Price

Worked example — Isolated

Isolated long, entry 80,585.8, size 0.001, leverage 120×, maintenance ratio 0.1, fee rate 0.05%.

Parameter	USDT
Open Price	80,585.8
Position Margin = 80,585.8 × 0.001 ÷ 120	0.6715
Open Fee = 80,585.8 × 0.001 × 0.05%	0.0403
Est. Close Fee = 0.001 × 80,585.8 × 0.05%	0.0403
Maintenance Ratio	0.10
Isolated Liquidation Price (price level — same on both)	80,021.7

7. Fees & Funding

Fee Type	Formula
Commission (open/close)	Margin × Leverage × Commission Rate (USDT)
Overnight Fee	Overnight Fee = Margin × Overnight Rate ÷ Leverage (USDT)
Funding Fee	Funding Fee = Position Value × Funding Rate (USDT)
Estimated Closing Fee	Estimated Closing Fee (INR) = Quantity × Latest Price × Contract Face Value × Fee Rate (USDT)

Note: Estimated closing fees are indicative and computed against the latest/estimated execution price; the actual fee is charged on the real fill price at close.

8. Risk Disclaimer

Futures trading involves substantial risk and can result in the loss of your entire margin. Leverage magnifies both gains and losses. The formulas and worked examples in this document are provided for transparency and education; actual fills, fees, mark prices and liquidation events are determined by the live matching and risk engines at the moment of execution. Users are responsible for understanding these mechanics and trading within their means.
