Script screener: run one script on a list of symbols

The script screener runs one AlertaScript on every symbol of a list and puts the results in a table: each plotted value becomes a column, and each alert condition shows whether it holds on the last closed bar or how many bars ago it last did. It is a Pro Lab tool, part of the Pro and Elite plans.

Running a scan

1. On a computer, press Pro Lab on the right-hand toolbar; on a phone, open the analysis centre from the chart's bottom bar and choose Pro Lab. Then choose Script screener.
2. Choose a script: a ready template, one of My scripts, or code you paste or write. Pasted code is not saved.
3. Choose the symbols: one of your watchlists or a ready list (top crypto on Binance spot, top Binance perpetuals, US large caps, or forex, metals and indices). Up to 60 symbols are scanned.
4. Choose the timeframe (15 minutes, 1 hour, 4 hours or 1 day) and 300, 500 or 1,000 bars per symbol, then start the scan.

Reading the table

• Values come from the last closed bar. Now means a condition holds on that bar; "3 bars ago" means it last held three bars back, within the last 50 closed bars.
• Markers the script draws, such as shapes and characters, are read the same way.
• Filters keep only the rows you want: a value above or below a number, or a condition that held within some bars.
• Click or tap a row for all its values and the condition history, and open the symbol on the chart from there.

Good to know

• Protected scripts are not listed, because they run only on their own charts.
• Symbols that could not be read stay in the table with the reason, and you can retry just those.
• One scan runs at a time on an account; stopping keeps the symbols already done.
