How OFSS is measured

Zone Terminal tracks OFSS on finished 5-minute candles. A Break of Structure needs a candle to close beyond a confirmed swing level; the last opposing candle before that move becomes the Order Block, kept only when a Fair Value Gap or a strong displacement confirms it. From there the terminal derives the zone (Z), the invalidation level and the next untouched liquidity pools.

OFSS isn't in the first release's ranked list yet. Tell us you trade it when you join the waitlist, and it moves up the queue for the next batch of stocks.

This page describes measurements only. It is not a recommendation to trade OFSS or any derivative on it.
