Spread is the gap between the buy and sell price of an instrument at that moment — a cost you pay the instant you enter, before the market has moved at all. On a prop account it counts twice: it reduces your net profit, and it eats into your daily loss limit, because every trade opens already down.

MyFxKit measures them live and refreshes them every few seconds. Every firm is put on one common unit, because each reports its spread in its own units and the firms would not be comparable otherwise.

Because each firm sources its liquidity differently and may add its own mark-up. Some quote a tighter spread but charge commission per lot, and some do the reverse, so spread alone is not the full cost — the TC Score weighs both together.

Every row carries the time it was captured, and freshness is judged when the page loads rather than from a stored flag. A stale row shows no price at all, and if nothing is fresh the page says so. Showing an old price instead of nothing is the worst thing a live spread board can do.
