In short
Your exchange liquidates you on the mark price, not the last traded price. The last price is simply the most recent trade on that one venue. It can spike or wick on thin volume. The mark price is a fairer, smoothed value built from live positioning across all major exchanges. Liquidation follows the mark so a single violent wick cannot unfairly close your position. This means your real distance to liquidation is the gap to the mark, not the gap to the last print. Watch the mark, size with room, and most wick panic disappears.
Two prices on every perp screen
Open any perpetual futures position and the screen shows you two numbers that rarely match. One is the last price, the other is the mark price. Most new traders watch the wrong one. That single confusion causes a lot of needless panic.
A third number sits behind both: the index price. It is the quiet anchor that keeps the mark honest. The table below sets the three side by side before we go deeper.
What is different here
The ParadiseTeam reads the mark across all major exchanges before building any setup. A single venue’s print is easy to fake and easy to misread.
| Price type | What it reflects | Where it comes from | Main use | Main risk to you |
|---|---|---|---|---|
| Last price | The newest completed trade | One exchange’s order book | Showing live ticks | Wicks and spikes mislead you |
| Mark price | A fair, smoothed value | Index plus funding basis | Liquidation and margin | Can differ from the last print |
| Index price | Average spot value | Spot across all major exchanges | Anchoring the mark | Lags a very fast move slightly |
What is the last price and why does it wick?
The last price is the price of the most recent completed trade on one exchange. It moves tick by tick with each fill. On thin order books it can spike or wick far from fair value, then snap back within seconds.
This wicking is why the last price alone is a poor guide to risk. Thin books, large market orders, and slippage on fast moves all push the last print around. The trade clears, the book refills, and the price returns. Your position was never really in danger.
What is the mark price and how is it built?
The mark price is a smoothed, fairer value an exchange uses to mark your position to market. It is anchored to an index price, which blends spot prices from all major exchanges. That anchoring filters out a single venue’s noise and manipulation.
Because it draws on many venues, the mark resists single-exchange manipulation. A major exchange’s explainer on mark price describes the same logic. The mark also reflects funding pressure, so it helps to understand funding rate regimes alongside it.
Why does liquidation use the mark, not the last?
Liquidation uses the mark so one venue’s wick cannot wrongly close healthy positions. If exchanges liquidated on the last price, a brief spike on thin volume would trigger a cascade. Marking to a cross-exchange value keeps liquidations tied to real market conditions.
Marking a position to a fair value is standard risk practice, not a crypto invention. It mirrors mark-to-market valuation used across regulated finance. The exchange needs one fair number to decide solvency. The last print on one venue is too easy to game for that job.
How the mark protects you from wick hunts
A wick hunt is a fast spike designed to trip stops and liquidations, then reverse. On the last price such a spike looks lethal. On the mark price it barely registers, because the index refuses to follow one venue’s stunt. This is the mark quietly protecting you.
So the wick that scares you is often not the wick that can liquidate you.
How close to liquidation are you really?
Your true distance to liquidation is the gap between the mark price and your liquidation price, not the gap from the last print. Check the mark on your position panel. A wick on the last price can look terrifying while the mark barely moves.
Read the gap from the mark, then plan your leverage around it. The wider that gap, the more room a position has to breathe. Good position sizing and survival means a normal wick never reaches your mark liquidation. That is how you stop closing good trades in fear.
Practical habits for watching the right price
A handful of habits keep you watching the right price under pressure. Judge your own routine against this checklist.
- Set price alerts on the mark, not the last price.
- Read your liquidation gap from the mark on every open position.
- Size leverage so a normal wick never reaches your mark liquidation.
- Ignore a single-venue wick until the index confirms the move.
- Check funding when the mark drifts away from the last price.
- When prices look chaotic, sit out rather than guess.
Red flags you are reading the wrong price
These habits quietly raise your risk. If you recognise any of them, fix it before your next trade.
- You panic at a wick without checking the mark price.
- You judge liquidation distance from the last print, not the mark.
- You set stops using only the last traded price on one venue.
- You trade thin books and ignore the index behind the mark.
- You stay in chaos instead of sitting a session out.
How the ParadiseTeam reads these prices
We have traded through several cycles since 2016, and this detail still catches experienced traders. So the ParadiseTeam always reads the mark against the index before acting, never a lone venue’s last print. We size so a routine wick cannot reach the mark liquidation. Protection comes first, the setup second.
None of this is a forecast. It is simply reading the number the exchange actually uses to judge you.
Frequently asked questions
Does my stop loss trigger on the mark price or the last price?
It depends on the exchange setting you choose. Many venues let you trigger stops on either the mark price or the last price. Mark-price stops avoid false triggers from wicks. Last-price stops fire on the exact print. Check your order settings before you rely on either.
Why is the mark price different from the last price right now?
The mark price is anchored to an index of spot prices from all major exchanges. The last price is just the newest trade on your venue. When one exchange runs ahead or lags, the two diverge. The gap usually closes as arbitrage pulls the venue back toward the index.
Can I be liquidated if the last price never hit my liquidation price?
Yes. Liquidation follows the mark price, not the last price. If the mark reaches your liquidation level, the position closes even if the last print never touched it. This surprises many new traders. Always read your liquidation distance from the mark, so the number you watch is the one that matters.
Is the mark price the same as the index price?
Not quite. The index price blends spot prices from all major exchanges. The mark price starts from that index, then many venues add a funding basis so it tracks the fair perpetual value. So the mark can sit slightly above or below the raw index at any moment.
Crypto trading involves substantial risk and is not suitable for everyone. Nothing here is financial advice; it is education only. Never risk more than you can afford to lose.
