Planning a Liquidation Buffer Before Adding Futures Leverage

Most liquidation problems start before the order is placed, not after. Traders pick a leverage number because it feels normal, enter a position size that feels affordable, and only later discover that the liquidation price sits far too close to the entry price. The fix is to reverse the order of decisions. Decide first how much adverse movement you are willing to survive, then work out the position size that keeps liquidation outside that distance, and only then choose leverage. This guide sets out a repeatable procedure for doing that on Bitget futures, using only figures you look up yourself in the official futures documentation and fee schedule. Nothing here is a prediction or a recommendation to trade; the aim is arithmetic and record-keeping that you can apply consistently. You will need your account equity, the contract specifications for the market you intend to trade, the current maintenance margin requirement, and the fee schedule. Treat every number as something to verify at the moment you use it, because margin tiers, contract sizes and fee rates change. The output of the process is a written position plan: entry reference, liquidation distance in percent, buffer, position size, leverage and a stop condition. If you cannot fill in every line, you are not ready to open the order.

Decide the liquidation distance before you touch leverage

Start with a percentage, not a leverage multiple. Ask what adverse move in the underlying price would tell you that your idea is wrong. That figure becomes your invalidation distance. Your liquidation distance must be larger than it, otherwise the market can liquidate you before your own thesis is invalidated, which means you lose the ability to exit on your own terms. A common working rule is to require liquidation to sit at least twice as far away as your invalidation distance, so that normal noise and funding-related mark price movement do not push you into liquidation while your reasoning is still intact. The multiple you choose is yours; what matters is that you write it down and apply it every time.

Bitget calculates liquidation using maintenance margin requirements that vary by position size and market. You can read the current tiers and formulas in the official futures documentation rather than assuming a single rate applies to every size. Because the requirement can step up as your position grows, a size that is safe at one tier may not be safe at the next. Before you calculate anything, note the tier that your intended notional value falls into, and re-check it after you have computed your size, since the answer may move you into a different tier and change the maintenance margin you used.

Write the liquidation distance as a percentage of entry price and keep it fixed for the session. If you later want to widen it, that is a new decision requiring a new calculation, not an adjustment made on the fly while a position is open. The whole point of doing this in advance is to remove mid-trade improvisation.

Turn the distance into a maximum position size

With the liquidation distance fixed, the position size follows from your equity and the maintenance margin requirement. The relationship is approximately: the percentage move to liquidation is roughly your initial margin percentage minus the maintenance margin percentage, adjusted for fees and funding. Rather than trusting an approximation, use the position calculator inside the Bitget futures interface, which applies the exchange's own formulas and current tiers. Enter your intended entry price, your chosen leverage and a size, then read the liquidation price it returns. Adjust the size until the liquidation price sits at or beyond your required distance from entry. This trial-and-error loop is faster and safer than deriving the formula by hand.

Check the result against your invalidation distance. If the calculator's liquidation price is closer than your buffer allows, reduce size or reduce leverage. Reducing size is usually the cleaner move, because it also lowers the notional value and may keep you in a lower maintenance margin tier. Increasing the margin you post has a similar effect but ties up more of your balance, which raises the cost of being wrong elsewhere in your account. Record which lever you pulled and why.

Fees matter at the margin. Opening and closing a futures position costs money, and the official fee schedule shows the maker and taker rates that apply. A liquidation distance that looks adequate on paper can be eroded by round-trip fees, particularly on smaller positions where fees are a larger share of the notional. Look up the current rates yourself and note them in your plan; do not carry a remembered number from a previous month.

Stress the plan against funding and volatility

Funding payments move your margin balance periodically. If you are on the paying side, your available margin shrinks over time even when price is unchanged, which pulls the liquidation price closer. Before opening, check the current funding rate and interval in the futures documentation or the market's information panel, then ask how many funding intervals you expect to hold. If the cumulative funding cost would consume a meaningful part of your buffer, either reduce size or shorten your intended holding period. Record the funding rate you observed and the time you observed it.

Volatility deserves the same treatment. Look at recent ranges on the market you plan to trade and compare them with your liquidation distance. If a single ordinary day's range is comparable to your buffer, the plan is too tight. This is not a forecast; it is a sanity check against observed behaviour. If the check fails, the correct response is a smaller position or a different market, not a hope that conditions will calm down.

Also confirm the contract specification you are trading: contract size, tick size, minimum order size and settlement currency. These details are in the official futures documentation and they determine whether your calculated size is even placeable. A size that rounds down below the minimum is a signal to reconsider the trade rather than to round up past your buffer.

Write the plan down and define stop conditions

A plan that exists only in your head will not survive contact with a moving market. Before placing the order, write a short record: market, direction, entry reference, invalidation distance, required liquidation distance, maintenance margin tier used, position size, leverage, liquidation price returned by the calculator, funding rate observed, fee rates observed, and the date and time of each lookup. Keep it somewhere you can read while the position is open. This record is what lets you tell later whether a loss came from a bad idea or from a badly sized position.

Define stop conditions in advance. Typical ones include: price reaches the invalidation distance, funding costs exceed the amount you budgeted, the maintenance margin tier changes because you added to the position, or you cannot verify a figure you relied on. When a stop condition triggers, close or reduce rather than recalculating the buffer to justify staying in. Recalculation under pressure is how buffers quietly disappear.

Finally, treat additions to a position as new positions. Adding size raises notional value, can move you into a higher maintenance margin tier and pulls liquidation closer, even if leverage appears unchanged. Re-run the full calculation for the combined position before adding, and if the combined liquidation distance no longer clears your buffer, the addition is not available to you at that size.

Scenario checkpoint

• Write your invalidation distance as a percentage before choosing any leverage number.
• Look up the current maintenance margin tiers in the official futures documentation and note which tier your intended size falls into.
• Use the position calculator to read the liquidation price, then adjust size or margin until it clears your required buffer.
• Record the maker and taker rates from the official fee schedule, plus the funding rate and interval you observed and when.
• Re-run the calculation for the combined position before any add, because tier changes move liquidation closer.
• Stop and close if price hits your invalidation distance, funding exceeds budget, or any figure in your plan cannot be re-verified.
