Buy here, sell there
Every coin on twenty-one exchanges, checked for a gap still there after both fees, and walked down both books to see what it’s worth.
Every exchange is on here, whichever you have on; your own choice still applies on every other page.
What this is
Gaps between exchanges that are still there after both fees, across twenty-one exchanges, ranked by what your amount makes down both order books. Live in your browser.
After both fees
Every gap is counted after both exchanges’ taker fees. Most don’t survive them; these did.
Down the books
What matters is how much a gap can take, so the top of the list is walked down both books and ranked by what your amount makes.
Prices, not predictions
A signal says where exchanges disagree, never which way a price will go. Standing, thin and pre-IPO markets are marked, so you know what you’re looking at.
What this is
Every market, every exchange
Your browser reads the best bid and ask of every market on every exchange the site covers, as the scoreboards do, so a gap anywhere is seen. Nothing passes through a server of ours.
Crossed, then costed
Where one exchange’s bid is above another’s ask, each exchange’s taker fee is taken off. A gap that’s gone after fees isn’t a signal.
Walked down the books
For the top of the list, both order books are read about once a minute and walked, to say how far the gap goes and what your amount makes. That, not the gap’s width, sets the order.
How to read the table
- 1
Your amount, your fees
The amount is what you’d spend on the cheaper exchange: a preset or your own. Taker fees are each exchange’s standard rate, or your tiers from a coin page’s Trade simulator. Beside them, narrow the list to a kind of asset, or to the new or standing gaps.
- 2
Buy here, sell there
Each row is a coin’s best pair of exchanges right now: buy at the ask on the first and sell at the bid on the second, at the same moment. The coin’s name opens its page, where both books are.
- 3
What’s left after fees
The bid above the ask, as a share of the ask, less both exchanges’ taker fees, at the best prices. Under it, the gap before fees and what the fees took.
- 4
What your amount makes
Walked down both books after both fees: what your amount makes, and how far the gap goes before it’s used up. Open for times it from when the page began reading; Standing, New and Thin say what to know before trusting it.
What each column means
- Buy at the ask
- Where the coin is bought: the exchange with the lower ask of the two, and that ask, the price a buy pays first.
- Sell at the bid
- Where it’s sold: the exchange with the higher bid, and that bid, the price a sale gets first. Prices in USDC, USDT and USDG are in dollars at Kraken’s rates, as everywhere on the site.
- After fees
- At the best prices: the bid on one above the ask on the other, as a share of the ask, less both exchanges’ taker fees.
- Goes to
- How much can go through before the gap is used up, walking both order books, and what that leaves after fees. The top 10 are walked, about once a minute each.
- 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.
- Standing
- Open the whole ten minutes the line covers, so likely for a reason: a currency that trades at a premium there, withdrawals that are slow or shut, or a book few trade on.
- New
- Opened since this page began reading.
- Pre-IPO
- The company isn’t listed, so there’s no share price to pull the two exchanges’ prices together: each follows its own market.
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.
Why so few after fees?
Because fees take most gaps, and the books take most of the rest: a gap at the best prices may cover only the first slice of an order. That’s why the list is ranked by what your amount makes, down both books.
What is a standing gap?
One open the whole ten minutes the line covers. There’s usually a reason a price stays apart: dollars that trade at a premium on one exchange, withdrawals that are slow or shut, a book few people trade on. It’s marked, so you can look for the reason first.
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 order books, funding rates and funding histories the rest of the site reads, straight from each exchange to your browser. Nothing is stored, and no server of ours sits in between.
Not financial advice. Prices move while you read them.
