Maximum edge ceiling

Max Edge Ceiling (in the Key Trading Rules group) is an upper limit on the modeled edge the bot will act on during Normal calendar slots.

Most edge controls set a floor — the bot needs at least so much edge before it trades (see Min Edge). The ceiling works the other way. When the bot's estimated edge on a trade is unusually large, that is more often a sign the model is miscalibrated on that contract than a real opportunity. Rather than take it, the bot rejects an entry whose modeled edge exceeds the ceiling. It is a winner's-curse guard — the component vocabulary calls it the Overpriced-Edge Guard.

How it is set

• The value is a fraction from 0 to 1. For example, 0.06 rejects entries whose modeled edge is more than 6%.
• 1, or unset, turns it off — because edge can never exceed 1.0, a ceiling of 1 never fires.
• Together with Min Edge (the lower bound), the ceiling brackets the band of modeled edge the bot will act on.

Scope

The ceiling applies only to Normal calendar slots. Deep-ITM slots are exempt — they keep their own edge floor from the Deep-ITM ruleset.
