Overview
OrderBlockRefiner TradingFinder takes an order-block type, refine flag, refine method, trigger condition and bar index, then measures candle range and body around that bar using a 55-period ATR. For demand and supply blocks it stores nearby open, high, low and close extremes and proximal and distal zone prices, choosing aggressive or defensive refinement. It returns calculated zone data rather than placing trades, and the excerpt shows no inputs or exit rules.
- Exported OBRefiner function
- Demand and supply order-block refinement
- Aggressive versus defensive proximal and distal lines
- Candle range before, at and after the block
- 55-period ATR measurement

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