his code is a Range Filter with entry signals.

How it works:
It calculates the average candle range (the difference between the price and its previous value) using EMA.
Based on this range, it builds a filter — a “smoothed line” (central level) along with upper and lower bands.
If the price moves above the filter → uptrend (green zone). If it moves below → downtrend (red zone).

Trade conditions:
longCondition (buy): price is above the filter and the filter has turned upward.
shortCondition (sell): price is below the filter and the filter has turned downward.
On the chart it displays:
the filter (line),
upper/lower bands,
colored candles (if enabled),
BUY/SELL labels and alerts.

In simple terms: it’s an indicator that filters out market noise and shows when the price changes trend direction, giving entry signals.
