ChartCrypto is a free, real-time cryptocurrency charting workspace that runs entirely in your browser. It brings together live market charts, a custom indicator editor, strategy backtesting, and a market scanner in one clean dashboard — with no signup, no paywall, and nothing to install.
Live charts for 1,000+ coins
Open a candlestick chart for Bitcoin, Ethereum, or any of more than a thousand listed altcoins. Charts load real-time price data with multiple timeframes, 100+ built-in technical indicators (RSI, MACD, Bollinger Bands, moving averages, and many more), and drawing tools for trend lines and annotations. Popular coins get dedicated pages such as the Bitcoin live chart and Ethereum live chart, and every chart supports keyboard-friendly navigation and dark mode.
Indicator Studio: write your own indicators
The standout feature is the Indicator Studio, a built-in editor where you can write custom indicators in a purpose-built DSL with autocomplete, syntax help, and inline documentation. Define your own calculations, plot multiple output series, and attach color rules — then run your indicator on any chart. Custom indicators are saved to "My Indicators" and can be reused, shared, and refined over time. For traders whose strategy depends on a calculation no platform offers out of the box, this removes the usual scripting barrier.
Backtesting and scanning
Test ideas before risking capital: the backtesting module runs indicator-based strategies against historical data and reports how they would have performed. The market scanner screens the whole market for technical conditions — RSI oversold/overbought, MACD crosses, moving-average crossovers — so you can spot setups across hundreds of pairs at a glance instead of opening charts one by one.
Portfolio, watchlist, and alerts
Track holdings with the portfolio tracker (live P&L), keep an eye on favorite assets with the watchlist, and set price alerts to get notified when a coin moves. A set of crypto-to-USD converters and regularly updated price-prediction pages round out the toolkit.
Free, private, installable
Everything works without an account. The site is a PWA, so you can install it to your home screen on mobile or desktop and get an app-like experience with an offline fallback page. Data comes from public exchange APIs rendered client-side, so your portfolio and watchlist stay in your own browser storage.
Whether you want a quick BTC chart, a full technical analysis workspace, or a place to prototype a custom indicator idea, ChartCrypto is a free and practical tool for crypto traders and researchers.
