NinjaTrader Multi-Timeframe Line Script

I need a custom NinjaScript for NinjaTrader 8 that automatically draws three horizontal lines from the 30-minute candle whenever that candle closes red (down). The script should: • Reference the 30-minute time frame only for its calculations. • Plot a line at the candle’s low, another at its close, and a third at the midpoint between the open and close. • Display those lines on every other chart I have open—Renko and Heikin Ashi included—regardless of their individual time bases. • Terminate each line at the close of the very next 30-minute candle so there is never more than one active set. My primary charts are both Renko and Heikin Ashi, and I will also need room to attach my own specific indicators to those Renko views, so please keep your code modular and avoid hard-wiring indicator slots. Deliverable: a compiled and open-source NinjaScript (.cs) that I can import, enable, and see working immediately, plus brief usage notes describing any parameters you expose. If anything in the brief sounds unclear, let’s clarify before you start coding so we can keep revisions to a minimum.
