This condition reads close directly against the nearest active zone's high and low. With evaluate: on_tick, close is the live 1-minute close - so the condition fires the moment price ticks into the zone, not at the next bar close.

Shape

{
  "type": "price_in_supply_demand_zone",
  "zone": "demand",
  "tolerance_pct": 0.1,
  "evaluate": "on_tick"
}

Params

zone - demand or supply.
tolerance percent - optional padding around the zone. 0 (default) = strict inside. 0.1 = 0.1% padding above the high and below the low.
evaluate - on_close (default) or on_tick. For zone-touch entries, on_tick is almost always what you want.

Requires the SUPPLY_DEMAND indicator

The zone boundaries come from the Supply/Demand indicator. Declare it in the strategy's indicators list. The condition returns false when no zone of the requested type is currently active.

vs supply_demand_zone

supply_demand_zone reads a precomputed closed-bar boolean ("did the bar's close happen to land inside the zone?"). It's correct for on_close strategies but slow to react.

price_in_supply_demand_zone reads the zone bounds directly against live price. With on_tick it fires intra-bar.
