Learning Pine Script: a small first project

You do not need to build a trading bot to benefit from learning Pine Script. A small indicator can help you understand how a chart value is calculated and which assumptions sit behind it.

Start with a visible calculation

Follow TradingView's first-indicator tutorial. Create a script in the Pine Editor, save it and add it to a chart. Change one input and observe what changes. Use the current documentation rather than mixing examples from different language versions.

A manageable learning sequence

1. Plot one familiar calculation.
2. Add an input with a clear name.
3. Explain the result on three different candles.
4. Check the unfinished candle separately from historical candles.
5. Only then add a condition or alert.

Write down what the script should do before adding features. If the result surprises you, simplify the script until you can explain it.

Find examples in the catalog, then use the creator's original publication to check code access.
