Step 1

How it works

This open-source utility accepts an Optimal Length as a TradingView source input and applies it to selectable calculations so users can compare how an adaptive length behaves against static-length workflows.

  • External source-driven length
  • Adaptive-length comparison
  • Multiple traditional indicator calculations
  • Visual backtesting context

Step 2

Set up the script

Open the original publication, choose Use on TradingView, then add the script to the intended symbol and timeframe. Review each input before relying on the display; defaults are a starting point, not a universal recommendation.

  • Add an Optimal Length source before selecting it here.
  • Choose the calculation to evaluate.
  • Compare the result with a fixed-length baseline.

Step 3

Create an alert

All current YinYang publications support TradingView alerts. Select a condition exposed by the script, confirm the symbol and timeframe, and test notifications before relying on them. This Alerts label does not by itself mean a webhook execution workflow has been verified.

Risk and results context

Signals, projections, and strategy outputs are analytical tools—not financial advice or guarantees of future results. Trading involves substantial risk.
