feature-f9-price-range

To filter trades by a stock price range, you configure a price-range filter using YAML-defined thresholds (`price_min` and `price_max`) to skip orders when `info.limit_up` falls outside the acceptable interval during the trading engine tick loop.

You prevent trading undesired low or high-priced stocks by enabling a price-range gate that skips orders when the comparison price is outside the configured `[price_min, price_max]` bounds in your strategy configuration.

You can turn off the price filter without changing other settings by toggling the `f9_enabled` YAML switch to false, which disables the order gating logic while preserving your configured `price_min` and `price_max` thresholds.

The price-range filter uses `info.limit_up` for order gating to ensure the comparison reflects the stock's limiting price, preventing the engine from missing ticks and executing trades outside the acceptable bounds.

To avoid high-priced stocks getting stuck, configure a price-range gate with an appropriate `price_max` limit and pair it with per-stock allocation limits in your trading selection pipeline to filter out stocks with insufficient tradable quantity.

The best way to integrate a price filter into a trading pipeline is to enable the F9 toggle in your YAML configuration and pair it with other filters, allowing the engine to gate orders based on `info.limit_up` during the tick loop.
