Overview

Grid Bot Predictive Ranges [psyll] determines grid envelopes using an ATR-based step algorithm across a configurable length and multiplier factor, with customizable offset and width constraints. Users can select between two boundary levels to tighten or expand the calculated range, and configure higher-timeframe security parameters to control repainting or lookahead behavior. The script displays price candles alongside the calculated grid levels in a separate indicator pane.

ATR-based predictive range boundary calculation
Configurable minimum and maximum grid width constraints
Multi-timeframe data support with configurable lookahead options
Dual-level sensitivity selection for envelope width
Custom price candle rendering in a separate pane

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
