Renko + PnF Bias Overlay v6

Description:
The Renko + PnF Bias Overlay indicator provides a synthesized directional bias derived from manual implementations of both Renko and Point & Figure charting methodologies applied to standard time-based price data.
The indicator calculates Renko brick movements based on ATR-derived brick sizes, creating a noise-filtered representation that only registers significant price movements exceeding the specified brick size threshold. Renko direction changes occur only when price moves a full brick size beyond the previous brick.
Simultaneously, the indicator implements Point & Figure box counting logic with reversal requirements, where directional changes require a minimum of three boxes in the opposite direction, providing additional filtering of minor price fluctuations.
By combining these two price transformation methodologies, the indicator generates a composite directional bias that emphasizes sustained price movements while filtering out minor fluctuations and noise. The resulting bias reflects the underlying trend direction as determined by both the brick-based momentum filtering of Renko charts and the reversal confirmation requirements of Point & Figure charting.
This approach provides a robust trend-following signal that requires both significant price displacement and sustained directional commitment before registering a change in bias.
