This is a auto trend I found in a file I had on my google drive. I don't know who made it.

The Ascend Trading Auto-Trendline Script does the following:

- Plots anywhere from 1-8 Trendlines depending on user’s preference selected in the scripts settings.
- The most current Trendline will be solid WHITE. Historical Trendlines will be on the chart as dashed lines.
- When a new Trendline is detected, the old one becomes dashed and remain for reference. The color of each line can be changed in the scripts settings.
- Plots a CYAN colored arrow either pointing Up or Down depending on if the candle closed above or below the current solid trendline. This annotates the point at which the trend was broken. When this happens you will also get an Audible
- Alert message with a sound saying “Possible Breakout” or “Possible Breakdown”. The arrow color can be changed and the audible alert can be disabled and messaged change if you wish.
- Displays a box at top left of chart giving you either a RED box saying “Below Current Trend” or a GREEN box saying
- “Above Current Trend”. This allows for fast reference to see where the ticker is at in its trend continuation.
