Arbitrage

Some traders don't beat the market. They beat your feed.

When your quote updates a fraction late, the next move is already known. They buy at the old price, and the profit is certain before the trade is placed.

One account, always listening

Your feed account stays logged in, recording every quote your server publishes. We compare it against an independent institutional reference feed and find every moment you were behind.

Once is luck. Dozens is software.

Entries landing inside stale windows again and again, with reactions under a third of a second, are not a trading style. The report shows each one, with both prices.

A flag, not a verdict

We hand you the evidence and you decide. The same check clears a trader who was accused wrongly. That is what an auditor is for.

Stale-window evidence starts the day the feed account connects. Markouts cover an account's whole history, because executed prices already sit in its own record.

How the check works

Plus one account for the feed

The arbitrage check needs one account of your own on each server your traders use. Any size. It never trades. We stay logged in and record the prices your server publishes, so recording starts the day it connects.
