Hey 👋
If you've ever wished an indicator did one thing differently, Pine Script is how you make that happen. Quick, plain-English tour.
What it is
Pine Script is TradingView's own little programming language for building your own indicators and strategies, right on the chart. You write a short script, add it to the chart, and it draws. No install, no separate software, it runs on TradingView's servers and shows up like any built-in indicator. The current version is Pine v6.
It's deliberately small and readable. You're not building an app, you're describing what to plot and when, candle by candle.
What you can build with it
- Indicators. Overlays on price (moving averages, bands, zones) or separate panes (RSI, volume, oscillators).
- Strategies. The same idea but backtestable. Define your entries and exits and TradingView simulates the trades so you can see how the rules would have behaved.
- Alerts. Fire a notification when your condition triggers, so you're not glued to the screen.
- Screeners. Scan a watchlist for the setup you actually care about.
Why it's worth learning
- It's free and built into TradingView, which millions of traders already use.
- You can read other people's open-source scripts and learn from the actual code.
- You go from idea to something on your chart in minutes.
A couple of honest gotchas
- Repainting. Some scripts change their past signals as new data comes in, they look amazing in hindsight and let you down live. The fix is to confirm signals on the candle close, not intrabar. I treat non-repainting on closed bars as a hard rule.
- It runs server-side with limits, it's for charting and signals, not high-frequency execution.
- A backtest is a sanity check, not a promise. Past behaviour isn't future results.
How I use it
Everything I publish is written in clean Pine v6. Proper logic, non-repainting on closed bars, no clutter, and open-source so you can read exactly how it works. Medusa and WidowMaker are both up there to take apart.
Grab the free scripts on TradingView, open the source, change a setting, see what happens. That's the fastest way to get a feel for Pine.
