Same contract, two prices
Futures and options across seven exchanges, checked for two prices apart after both fees: dated futures on the same expiry, and the same option.
Every exchange is on here, whichever you have on; your own choice still applies on every other page.
What this is
Futures spread trades and options priced apart across seven exchanges, after both fees, every coin and expiry at once. Live in your browser.
Futures spread trades
The same coin and expiry on two exchanges: short the dearer, long the cheaper, and what they’re apart is kept at expiry, less both fees.
The same option, two prices
Bitcoin’s and ether’s options on Deribit by Coinbase and OKX, where one’s bid is above the other’s ask after both fees.
Prices, not predictions
A signal says where exchanges disagree, never which way a price will go. Where your amount is more than a best price holds, or two legs settle apart, it says so.
What this is
Every expiry, every exchange
Your browser reads every option and dated future on the seven exchanges whose figures it can read, every minute, as the futures and options pages do. Nothing passes through a server of ours.
Futures, apart until expiry
For each coin and expiry, the two exchanges whose futures are furthest apart over their own indexes, at the prices they’d trade at: short the dearer, long the cheaper, and what’s left when both settle is the gap, less both fees.
The same option, two prices
Deribit by Coinbase and OKX list the same bitcoin and ether options. Where one’s bid is above the other’s ask after both fees, buying on one and selling on the other, held to expiry, keeps the gap.
How to read the table
- 1
Each leg, a coin, an expiry
Each leg is the size of each side of a futures spread trade: a preset or your own. Narrow the lists to one coin, or to expiries within a month or after it. Fees are each exchange’s standard taker rate.
- 2
Short here, long there
Each row is a coin’s expiry: short the future dearest over its own exchange’s index at its bid, long the cheapest at its ask, the same coins on each, so price moves cancel out. Each premium is a rate a year.
- 3
Apart now, and by expiry
Apart is the two premiums’ difference, in points a year; under it, what that comes to as a share of a leg by the later settlement, before fees.
- 4
What’s left after fees
What your amount a leg keeps at expiry after both taker fees, and under it as a rate a year; a mark beside a leg where its best price holds less. Settle says when the two settle; Open for, how long the pair has paid after fees since the page began reading.
What each column means
- Short at the bid
- The future dearest over its own exchange’s index on this expiry, at its bid, and that premium as a rate a year.
- Long at the ask
- The cheapest over its own exchange’s index, at its ask, and that premium as a rate a year.
- Apart, a year
- The short’s premium less the long’s, in points a year; under it, what that comes to by the later of the two settlements, as a share of a leg, before fees.
- Settle
- When the two settle: together at 08:00 UTC, or apart where one is Coinbase’s, at 4 pm in London. Between the two, one leg is open on its own.
- Open for
- How long the gap has been open after fees, and its last ten minutes, from when this page began reading. A + means it was open already when the page opened.
- More than on offer
- A mark beside a leg: your amount a leg is more than its best price holds, so the rest would trade at worse prices, which isn’t counted here.
Questions signals raise
Is a signal advice?
No. It says two exchanges disagree on a price right now, and what that comes to after their fees. It never says which way a price will go. Not financial advice.
Does a futures spread trade lock the gap in?
Nearly. Each future settles on its own exchange’s index, so what they’re apart now is what’s left at expiry, whichever way the price goes. Not quite fixed: the two indexes can end a few dollars apart, fees to settle aren’t counted, and each leg holds its own margin until then.
Why only Deribit by Coinbase and OKX for options?
They list the same bitcoin and ether options: struck in dollars, priced and settled in the coin at 08:00 UTC. Bybit’s are struck and settled in tether on its own index, so a gap against it isn’t locked in; each coin’s futures and options page compares those in volatility, marked.
Why are options so rarely priced apart after fees?
Because a crossing between the two is usually a tick or two, less than both fees: when bitcoin’s were measured on 18 Oct 2026, nine of the 556 options both listed were crossed, each by a tick, and none by more than both fees. The figures here are up to a minute old, so check both books before you trade.
What is max pain?
The price at which the options expiring on a date, on every exchange together, would be worth least to their holders at settlement. It’s worked out from open interest alone, and it says nothing about where the price will go.
Do I need an account on both exchanges?
Yes, with money or coins already on each: buying on one and selling on the other at the same moment needs both sides funded. Moving coins between them takes time, and a withdrawal fee this page doesn’t count.
Where does it all come from?
The same public option chains, dated futures and indexes the futures and options pages read, straight from each exchange to your browser, every minute. Nothing is stored, and no server of ours sits in between.
Not financial advice. Prices move while you read them.
