Bitunix Futures Guide: Margin, Funding, TP/SL & Liquidation

Start with the contract, not the leverage slider

Read the selected symbol, settlement asset and product details. A contract can track the same underlying asset as a spot pair while having its own price and costs. Long and short describe exposure direction, not certainty about the next candle.

Write down a condition that would disprove the setup. Calculate the amount you could lose at that exit, including an allowance for costs and possible slippage. Choosing size first and then moving the stop to justify it reverses that process.

Notional and initial margin: a simple example

In a simplified example, 500 USDT of initial margin at 5× supports 2,500 USDT of notional exposure. A 1% adverse move represents approximately 25 USDT of price loss, or 5% of that initial margin, before fees and funding. This is arithmetic, not a liquidation formula.

Actual required margin and liquidation depend on contract rules, maintenance requirements, account settings and position changes. Never infer an exact liquidation price from leverage alone.

Cross margin and isolated margin

Bitunix’s futures terminology guide distinguishes isolated position margin from a shared cross-margin pool. Read the mode on the order panel and on the position itself. Shared collateral can expose more of the applicable account balance; isolated margin requires attention to allocated collateral.

Do not assume an isolated setting makes a trade harmless or that adding margin repairs a failed setup. Before entering, understand any automatic margin-replenishment setting and what funds it can use.

Mark price is different from last price

The last price is the latest executed trade. The platform’s mark price is a separate risk reference. Inspect the contract’s liquidation rules rather than assuming the visible candle must touch a particular price before liquidation. The official liquidation guide explains the role of margin requirements and risk calculations.

A displayed liquidation estimate is not an exit strategy. Liquidation can remove your control over closing a position. Plan an invalidation well before relying on the platform’s forced-close process.

Funding and holding a perpetual position

Funding can add a payment or receipt at the contract’s settlement times. Check the current countdown, sign and position notional. Intervals can differ by contract, so one generic “every eight hours” assumption is insufficient.

A trade can be directionally correct and still produce a disappointing result after costs. Keep a record of opening and closing charges and each funding settlement. See the Bitunix fee examples for the distinction between margin and fee notional.

TP/SL and the pre-order checklist

Take-profit and stop-loss instructions define conditions for an exit, but trigger basis and execution method matter. A stop-market order can slip; a stop-limit instruction may fail to fill. Check whether an exit reduces or closes the intended position and whether any old orders remain.

Before any live order, confirm contract, direction, quantity units, margin mode, collateral, leverage, estimated costs, trigger reference and invalidation. Use a demo environment where available to learn the controls without turning the learning exercise into a leveraged bet.
