Overview
Auto Dynamic Trendlines finds pivot highs and pivot lows with a fixed 15-bar lookback on each side, keeps the last two of each, and on the latest bar connects those highs with a red line and those lows with a green line, both extended to the right. There are no user inputs, alerts, or trade signals. Lines are rebuilt only on the last bar and are limited to ten drawings.
- 15-bar pivot high and low detection
- Red resistance line from last two highs
- Green support line from last two lows
- Lines extended to the right
- Maximum of ten line drawings
