Prices being checked

A price that moves 30% or more, or would reach a top three, waits for a second reading at least 12 hours later and is checked against the provider's own page, and so is one that fails a check or that a reader reports. Meanwhile the price shows its last confirmed price and leads no list. Nothing is being checked today.

How the numbers are protected

• Only fetched numbers. An adapter throws on anything it does not recognise, and nothing is typed in by hand.
• A broken read is refused. Half the rows gone, or a typical price moved 2.5 times, keeps the last reading.
• A changed price waits. A move of 30% or into a top three shows once a second reading agrees.
• Credits at the provider's own rule. Credits become searches at the rate the provider states.
• One unit. Every price is per 1,000 searches; typical today, $7 per 1,000 searches.
