Tell the AI what you want in plain words. Pine Lab writes the Pine Script, runs it on a live chart and backtests your strategy, so you can see if the idea works.
Indicators and strategies · Pine Script v6
Turning a setup into a script used to mean learning to code first. Most ideas never made it that far.
You know the setup you want, but learning a scripting language takes weeks before you can test it.
Without a script, a promising rule stays a hunch. You can't see how it would have played out.
Scripts from forums break on the first error, and you're left guessing what the message means.
No setup and no syntax to learn. Start with what you already know about the market.
Indicators draw signals and levels on the chart. Strategies add buy and sell rules you can backtest.
Write it the way you'd explain it to another trader. If something is unclear, the AI asks a quick question first.
The script runs on a live chart. Check the results, ask for changes, and keep going until it's right.
Ask it to write something new, explain a script line by line, or find out why one won't run. It works on the code that's open in front of you.
The AI never hides what it did. See exactly which lines changed, undo anything you don't like, and go back through the history of your script.
Run a strategy and its trades appear on the chart, with results right underneath. Change the data range or the settings and run it again.
Chat, chart, code and results in one place, built for how traders actually work.

No. You can build a script entirely by describing it. If you do know Pine Script, the full code is always there to read and edit yourself.
Pine Lab uses Pine Script version 6, so most scripts work as they are. If a script uses something that isn't supported yet, the editor points to it and the AI can suggest another way.
Yes. Paste your code into a new script, run it on the chart, and ask the AI to explain or improve it.
Every AI change shows exactly which lines were added or removed, and you can undo it in one click. Your script's history keeps earlier versions too.
Yes. Run a strategy to see its trades on the chart and its results underneath, including P&L, win rate, profit factor and drawdown.
