Closed bar inside S/D zone

supply_demand_zone returns true when the closed bar's close sits inside the nearest active zone. It reads a precomputed flag from the Supply/Demand indicator.

Shape

{ "type": "supply_demand_zone", "zone_type": "demand" }

Params

• zone type - demand or supply.

vs price_in_supply_demand_zone

• supply_demand_zone: closed-bar, deterministic, matches backtest fills exactly. Use with the default on_close evaluation.
• price_in_supply_demand_zone: live-price, designed for on_tick evaluation, fires intra-bar.

Pick one or the other, not both. They will conflict on bars where the close lands inside the zone but the wick didn't (or vice versa).

Pitfalls

• Requires the SUPPLY_DEMAND indicator to be declared.
• Closed-bar evaluation means you miss zone touches that happened intra-bar and got rejected before close.
