Pine Technical Analysis Library: Indicators, Adaptive Averages, and Volume Tools
Summary
This Pine Script library collects reusable calculations for a broad set of technical analysis and trading functions. Its exports include moving averages and oscillators, trend and volatility tools, channel and stop calculations, fractal detection, percentage change, and compound annual growth rate. Several alternative versions accept dynamic series lengths, extending standard calculations to inputs that vary over time.
The code illustrates implementation choices, including a dynamic exponentially weighted average used by multiple functions, ATR-based Chandelier exits, and a CAGR calculation that requires at least one day between the supplied timestamps. It also includes functions to request lower-timeframe up/down volume and volume delta, plus a Williams fractal detector that allows some equal neighboring values.
This is a code reference, not a trading system or empirical study. The excerpt lists many exports but omits much of their implementation, and it reports no comparative tests or profitability evidence. Users need to inspect function definitions and input constraints before relying on any calculation in a strategy.
Key ideas
- The library provides reusable functions spanning trend, momentum, volatility, volume, and other technical calculations.
- Some alternative averages and ATR-based functions support dynamic series lengths.
- The CAGR function returns no value when the supplied interval is shorter than one day or prices are missing.
- Lower-timeframe volume requests and Williams fractal detection are among the included tools.
- The library documents calculations but provides no evidence that they produce profitable strategies.
