# LiquidityMapperFast

> A liquidity heat map for crypto markets that runs in the browser: the order books, trades, liquidations and taker flow of many exchanges, read from their public APIs, with indicators people write as scripts.

The page has no API and no server of its own: it reads the exchanges directly from the visitor's browser, and a script runs in the visitor's browser too. Scripts are kept in the browser (exported and imported as files).

## Scripts

- [Script language reference](https://liquiditymapperfast.github.io/script-reference.md): the whole language, its inputs, functions, plots, limits and every error code with a script that meets it and the fix.
- [Machine-readable reference](https://liquiditymapperfast.github.io/scripts.json): the same as JSON.
- To help someone with a script, ask them to open it in the Scripts panel and press Copy for AI: the copied text holds the script with line numbers, its errors with codes, and what it last drew. Answer with the whole script in one code block.

## The page

- [LiquidityMapperFast](https://liquiditymapperfast.github.io/): the map. Address parameters: ?coin=ETH (the coin), ?lang=de (the language), ?source=browser (read the exchanges from the browser), ?persist=0 (keep nothing in the browser); #guide opens the guide.
- In a browser that offers page tools to agents (WebMCP, document.modelContext), the open page offers: get_page, get_script_language, list_scripts, get_script, read_script, try_script (runs a script once over the chart; saves nothing), propose_script (opens a draft the person saves or drops) and set_timeframe. No tool saves a script, switches one on or reaches anything beyond the page.
