AcidX — our own terminal

Where the prices come from

Public cryptocurrency exchanges — Binance, with Kraken as an automatic backup. We add no spread markup and take no commission: the bid and ask you see are theirs.

How a fill is decided

Your order is held for a fraction of a second and then filled at the market price when that delay expires — never at the price on your ticket. That is what makes a stale quote worthless to a bot, and it is why there is no minimum hold time here.

When the market moves too far

If the price moves more than 0.25% between your click and the fill, the order is refused rather than filled somewhere you did not choose.

When the feed breaks

We switch to the backup exchange automatically on the majors — six of the nineteen pairs have no second source, so for those a primary outage is an outage. If neither answers, prices go stale: no order can be filled — opening OR closing — until a fresh price arrives. Nothing is closed for you, but a position cannot be exited during the gap either. This is why the feed runs on several sources at once.

Every fill keeps its receipt

The price you asked for, the price you got, the delay and the difference are stored with the trade, and every tick we served is archived. A disputed fill is answered with the record.
