Now charting Bitcoin in USD. Prices: Binance public market data, near real-time, for information only - not investment advice. Your drawings and settings are saved only in this browser and never leave your device.
Chart Studio
Your chart. Your lines.
A charting tool that is fully ours: live candles from one minute to one week, indicators, and real drawing tools - brush, trend lines, channels, Fibonacci. No third-party frames, and every drawing stays on your device, saved per symbol.
Technical signal
for BitcoinReading the candles...
A plain-English read of common indicators (moving averages, RSI, MACD) on the timeframe you are viewing. Calculated by Chrysofi in your browser, updated live. It is a summary, not a recommendation to buy or sell.
DrawPick a tool on the left, then click once to start and once to finish. The brush works by holding the mouse (or your finger) down and drawing.
EditSwitch to the select tool, then drag a line's end points to adjust it. Undo removes the last drawing; Clear wipes the chart for this symbol.
KeepDrawings are saved automatically per symbol on this device and reappear next visit - on any timeframe, because they anchor to time and price.
About the Chart Studio
Most chart widgets are borrowed: an embedded frame served by someone else, with their branding, their limits and their tracking. The Chart Studio is different - the chart engine is open source, lives on Chrysofi's own servers, and draws everything on a plain canvas in your browser. That is why it starts fast, follows your site theme (including dark mode and accent colors) and works the same on a phone as on a desktop.
Prices cover major cryptocurrencies plus gold through PAXG, a token backed by physical gold that closely tracks the spot price, all quoted in US dollars. History loads as you scroll left, and the last candle updates live over a streaming connection (if that is blocked on your network, the page quietly falls back to refreshing every few seconds - the status pill in the corner tells you which mode you are in). Stocks and indices need paid data feeds, so for those the Market Terminal keeps a full TradingView chart.
Privacy is simple here: your drawings, indicator choices and timeframe are stored in your browser's local storage, per symbol, and are never sent to Chrysofi or anyone else. You can share a specific view by copying the address - the symbol and timeframe travel in the link, like this hourly Ethereum chart - but your drawings stay yours.
None of this is investment advice. A trend line is a thought, not a guarantee. When you are ready to act on one, pressure-test the idea with the investment growth calculator or any of the financial tools.
