The scanner ranks every route by net spread through the order book, after both legs’ fees, with alerts to Telegram and a trade journal. The first week is free.
Below are the venues the scanner watches for 4, each against the average of them all, and the perpetual’s premium over spot where one exchange quotes both. The best buy and the best sell are picked among venues in one quote currency.
A gap at the touch is not what you get: the book under it, the fees of both legs and the time to move funds eat into it. The pairings the scanner ranks are measured through the book at a given size and after fees — that is the net spread, and that is what to compare.
The first pairings are shown here as they stand right now; the whole list with filters, alerts and the journal is in the scanner.
FAQ
Why is 4 priced differently on each exchange?
Every exchange is its own market with its own buyers and sellers; prices converge through arbitrage, not by decree, so a gap is always there and never exactly zero.
Is the best spread shown here what I would get?
No — it is the gap at the touch before fees. The scanner measures each pairing through the order book at your size and after both legs’ fees.
