What to use instead of ChartIQ

The product

ChartIQ is a JavaScript charting library for financial front ends — the chart a broker, a research portal or a market-data vendor embeds in its own web and mobile apps. Its documentation, read on 9 October 2026, covers technical studies and a scripting language for new ones, ScriptIQ; drawing tools from trendlines to Fibonacci, Gartley and Elliott wave; market depth and cross-section charts such as yield curves; options analysis; trading from the chart; and, in the 10.x releases, an AI plugin that drives the chart from a command line or a conversation. Version 10.5.0 is dated 9 September 2026. Which of those you get depends on the package you license.

It changed hands at the turn of 2023. S&P Global's press release of 5 January 2023 announced the acquisition of ChartIQ from Cosaic, signed on 23 December 2022 and closed on 1 January 2023, for undisclosed terms, to sit inside S&P Global Market Intelligence alongside Capital IQ Pro. The release said S&P Global would continue to license the charting packages on their own. The old chartiq.com address now redirects to an S&P Global Market Intelligence page.

The licensing is the reason most people look elsewhere. There is no price list. The library is not on the public npm registry — the chartiq package there is a placeholder that tells you to contact your account manager — and it is delivered as a zip archive built for one customer. A production key in key.js is locked to your domains, IP addresses or file system and to an expiration date, and the documentation says plainly that "the library will stop working once the expiration date is reached". Expiration locks run for a year unless arranged otherwise. A lapsed renewal is not a missed upgrade; it is a blank chart in production.

What to use instead

None of these is ChartIQ under another name; each covers part of it. Decide which part you licensed it for. The licence terms behind every option below are compared in what a charting library licence allows, and the whole field is in charting libraries.

A full trading chart with indicators and drawings. TradingView Advanced Charts is closest in breadth, with 100-plus indicators, 110-plus drawing tools and a datafeed interface you implement, and costs nothing — but its agreement grants it only to companies offering a free public service, never to a paid, internal or open-source product. Among libraries with a published price, Highcharts Stock ships 48 indicators at 732 dollars a seat a year for one public application, AnyStock 36 indicators and 18 drawing tools from 499 dollars a year for a SaaS product, and amCharts 5 Stock Chart 34 indicators, free in a commercial product while its branding link stays on the chart.

Open source. KLineChart is the open-source library that still has indicators — 27, under Apache-2.0. Lightweight Charts is the plain price chart with none. Apache ECharts and Plotly.js draw candlesticks inside general-purpose charting, for a dashboard or for charts that begin in Python. All four leave the indicators, beyond KLineChart's set, to your code.

Speed. If the commercial library was bought to draw a lot of ticks quickly, SciChart.js is the GPU-rendered option, sold per developer — with no technical indicators in the package at all.

What you give up

The specialist modules. Options analysis, term structures and cross sections, ScriptIQ, and trading from the chart are in ChartIQ's documentation and on none of the cards above. Order entry on a TradingView chart is a separate product, Trading Platform, which its card describes as quote-only. Expect to build the options and fixed-income views yourself.

One supplier for the chart and the data. ChartIQ's documentation describes reference-data datasets — consensus, financials, guidance — that a licensee can feed onto the chart, and its owner sells data. Every pick here ships no market data; the feed is a separate contract and a separate adapter.

A support contract. A quote-only licence buys an account manager and a service agreement. The open-source libraries have issue trackers; the commercial ones sell support by seat or by hours.

Migration notes

Move before the key expires, not after. Read the expiration date in the comments at the top of key.js and plan the cut-over against it. On SciChart.js, by contrast, runtime keys are perpetual and a lapsed subscription costs you only new versions.

Rewrite the quotefeed as a datafeed. ChartIQ pulls bars through its own quotefeed interface. Advanced Charts, Highcharts and the rest each want their own adapter, and the open-source libraries mostly want arrays you fetch yourself. The data contract does not change; the code around it does.

Indicators will not print the same numbers. Each library implements RSI, MACD and the rest its own way — smoothing seeds, warm-up bars, session boundaries. Diff the old and new values on closed historical bars before you ship, and see why indicator values differ for where they part company.

Saved layouts and drawings stay behind. ChartIQ serialises chart state in its own format, and no card here documents an importer for it. Plan to tell users that saved drawings will not carry over, or write the conversion yourself for the few drawing types you need.
