Free crypto trend indicator: the SMMA 15/29 Pine Script

The free SMMA 15/29 crypto trend indicator is a Pine Script you can add to any TradingView chart. Copy it below. It's open source (MPL-2.0), with no signup and no black box: the same indicator that powers the Crypto Trend Index and our daily trend-flip scan.

What it does

The script plots two smoothed moving averages on your chart: a fast SMMA 15 and a slow SMMA 29. When the fast line is above the slow line the trend is up and the lines turn green; below means down and red. Two helper averages (19 and 25) mark the transition zone in gray, so you don't read a flip into every wobble.

What is the smma-15-29 indicator?

Two smoothed moving averages: a fast SMMA 15 and a slow SMMA 29. When the fast line is above the slow line the trend is up; below means down. The lines are colored green, red, or gray accordingly.

Can I run this across all coins at once?

Not in TradingView: a Pine Script runs on one chart at a time. Squarito runs the same signal across the top 5000 crypto assets daily and emails you when a coin's trend flips. A free account unlocks that.

The script is provided as-is under MPL-2.0. Open code is the point; see how that compares to paywalled trend indicators. This page is for informational purposes only and is not financial advice.
