Pine Script v6 · TradingView indicator + Python microservice
HTF Mirror projects the developing higher-timeframe (HTF) candle — default 4H — into the right margin of any chart: solid body, dotted range footprint, open level, equilibrium, and a High / Low / Last + countdown label.

Stateless Python microservice. Exposes the same projection math over HTTP so external engines (MT5, Python bots, backtesters) can consume it. | service/ |
| Element | Description |
|---|---|
| Projected candle | Solid body + wick of the developing HTF candle, drawn in the right margin. |
| Dotted range footprint | High/low box of the live HTF candle from period start. |
| Open level | Dotted line at the HTF open. |
| Equilibrium | Dotted line at 50% of the range (high + low) / 2. |
| Side label | High / Low / Last price and countdown to HTF close. |
| Group | Key inputs |
|---|---|
| HTF | HTF timeframe (default 240 = 4H), manual label prefix. |
| Projection | Right-margin offset, body width, toggles for range / wick / open / EQ. |
| Style | Monochrome or PO3 gradient (bull / bear / weak), transparency. |
| Label | Size, countdown toggle. |

The projection uses non-repainting request.security with lookahead_off. The
developing candle updates live (intrabar).
Pine runs only inside TradingView — it cannot be containerized or called by an
external engine. The service/ directory ports the indicator's deterministic math
to a stateless FastAPI service so any trading engine can obtain the same projection
over HTTP.
