OP Liquidation Calculator
The quick answer: a Optimism (OP) long is liquidated roughly 1 ÷ leverage below your entry (minus a ~0.5% maintenance margin) - about 9.5% at 10×, ~3.5% at 25× and ~0.5% at 100×; shorts mirror the same distance above entry. The calculator below gives your exact price for any entry, leverage and side - free, instant and private (it runs in your browser).

OP is trading at $0.1163 right now, little changed over the past 24 hours. From this price, a long is liquidated near $0.105252 at 10x, $0.11223 at 25x, $0.114556 at 50x and $0.115719 at 100x (0.5% maintenance margin) - short levels mirror the same distances above the price. The past 24 hours were quiet for OP - the move stayed inside even a 100x buffer, which is the exception rather than the rule. Funding is currently flat (+0.0000%), so holding a leveraged OP position costs little either way right now.

How OP liquidation works
Optimism perps track the broader L2 sector and react to airdrop/unlock events. Liquidation happens when losses eat through the margin backing your position - the exchange force-closes it to stop the loss going past your collateral. The isolated-margin estimate is Entry × (1 − 1/Leverage + MMR) for a long and Entry × (1 + 1/Leverage − MMR) for a short, where MMR is the maintenance margin rate (about 0.5% on most OP perpetuals). OP futures list up to 75× leverage across the major venues, but the headline cap is a trap: the higher you go, the closer liquidation sits to your entry.
OP liquidation distance by leverage
How far Optimism has to move against an isolated-margin long before it is liquidated, at a 0.5% maintenance margin:
| Leverage | Move to liquidation | Initial margin |
|---|---|---|
| 5× | −19.50% | 20.00% |
| 10× | −9.50% | 10.00% |
| 25× | −3.50% | 4.00% |
| 50× | −1.50% | 2.00% |
At 100× a move of about 0.5% wipes the position; at 5× you get roughly 19.5% of room. Because Optimism routinely moves several percent in a session, most traders who last keep OP leverage in the low-to-mid range and let the position breathe.
Worked example - 10× OP long
A 10× OP long entered at $1.5 with a 0.5% maintenance margin rate is liquidated at about:
Enter your own numbers above - the calculator prefills the live OP price, so you can see exactly where a real position would be wiped right now. Set your stop-loss comfortably inside that level and size by risk.
Common ways OP traders get liquidated
- Chasing max leverage. 75× on OP means a ~1.33% wick against you is game over - and OP prints wicks like that regularly.
- No stop-loss. Without a stop, the exchange's liquidation engine becomes your exit - at the worst possible price, plus a liquidation fee.
- Ignoring funding. On a crowded OP trade, funding drains your margin every 8 hours, nudging liquidation closer than the raw price math shows.
- Sizing by dollars, not risk. Size from your stop distance instead - see the position-size calculator.
See OP liquidations happen live
Numbers are one thing; watching real leverage get wiped is another. The live liquidations feed and the Rekt ticker show OP longs and shorts being force-closed across eight exchanges (Binance, Bybit, OKX, Hyperliquid, Gate, HTX, dYdX, Bitfinex) in real time - a spike in long liquidations often marks local capitulation, a spike in shorts a squeeze. Then rehearse the trade with zero risk on the OP paper-trading terminal at the live price, and screen the whole market on the futures screener.
FAQ
At what percentage is a OP position liquidated?
Roughly 1 ÷ leverage, minus the maintenance margin. A 10× OP position is liquidated after about a 9–10% adverse move; 25× after ~4%; 100× after ~1%.
Does the OP liquidation price change with position size?
For isolated margin, no - the liquidation price depends on entry, leverage and MMR, not on how big the position is. For cross margin your whole wallet balance backs the trade, which pushes liquidation further away; model that with the cross-margin calculator.
Is this OP liquidation calculator accurate?
It uses the standard isolated-margin formula and your exchange's maintenance margin. Real liquidation can differ slightly because of fees, funding and tiered maintenance margin on very large positions - treat the figure as a close estimate and leave a buffer.
