BYDFi futures liquidation 2026: fair price trigger, MMR 100%, alerts and checklist

What liquidation means on BYDFi

Liquidation is not a slap on the wrist. When MMR reaches or exceeds 100%, the system moves through a defined process that can cancel orders, reduce exposure, and close size. Margin assigned to that risk can be lost. The goal of tiered handling is to avoid always wiping a full position in one shot when risk limits allow a partial path — but you should never plan on surviving 100% MMR.

Fair price is the liquidation reference

BYDFi uses fair price (mark) as the reference that triggers liquidation when it reaches your liquidation price. That design reduces unnecessary liquidations from short-lived last-price spikes. On the futures ticket you can watch fair price, last price, and index price in the header and on the chart switcher.

Trading habit: if last price wicks through your mental stop but fair price has not, risk systems may still be calm. If fair price is marching toward liquidation, last-price hope will not save the ticket.

What pushes MMR to 100%

MMR rises when unrealized losses consume margin relative to maintenance requirements. High leverage, adds without adding margin, funding drains, and sudden adverse fair-price moves all compress the buffer. Isolated mode contains damage to the position's posted margin. Cross mode shares available margin across eligible exposure — which can save a position or transmit losses.

How the liquidation process typically unfolds

Venue FAQ material describes a staged path after the trigger:

1. Order cancellation — open orders can be cleared (scope differs for cross vs isolated with auto-margin behaviors).
2. Long-short self trading in cross — opposing positions may net when rules allow.
3. Tiered liquidation — reduce toward lower risk tiers instead of always full close when possible.
4. Further forced reduction or full liquidation if MMR remains at or above 100%.

Exact pathing depends on margin mode, risk limit tier, and live account state. Read the position panel after every change; do not memorize a blog diagram and ignore the live MMR.

Tools that help before you hit 100%

• Prefer isolated margin while learning so one ticket cannot vacuum the whole futures wallet.
• Cap leverage so liquidation sits beyond your planned invalidation.
• Use TP/SL and reduce-only closes; know that extreme volatility can still slip market exits.
• Enable liquidation alerts under futures preferences when available, with an MMR threshold you will actually respect.
• Shrink or add margin early when MMR climbs — waiting for the alert is late.

Practical pre-trade checklist

1. Confirm pair, fair price, funding, and leverage before entry.
2. Choose Isolated or Cross deliberately.
3. Set protective exits immediately after entry.
4. Recalculate liquidation distance after every add.
5. Flat or cut when MMR approaches your personal hard stop (well below 100%).

Tips

• Treat fair price as the risk truth; treat last price as the discretionary tape.
• After a partial liquidation, reassess — surviving one stage is not a green light to add.
• Funding and fees matter more when you are already near maintenance.
• Paper the full close path once on a tiny size so the UI is familiar before stress hits.

Risks

• Liquidation can realize a full margin loss even if price later reverses.
• Slippage on protective market orders can underperform the stop you typed.
• Cross margin can cascade across positions.
• Alert throttles (for example limited alerts per window) mean you cannot outsource vigilance.
• Auto-margin features can deepen losses if they keep a doomed ticket alive longer than your plan allows.

Short FAQ

What price liquidates me?

Fair price reaching the liquidation price, with MMR at or above 100%, per venue risk rules.

Does last price liquidate me directly?

Risk reference is fair price. Last price still matters for fills and discretionary management.

Will TP/SL always save me?

No. Gaps, insufficient size, and volatility can cause misses or slippage; treat them as aids, not guarantees.

Isolated or cross for beginners?

Isolated is usually clearer because losses are ring-fenced to posted margin.
