Lovable TradingView charts come in three forms, and they are not interchangeable. Embed a free widget and you get TradingView's chart and TradingView's market data. Install Lightweight Charts and you get a library that draws your own data. Apply for Advanced Charts and you get the full charting product. All three are free. All three carry an attribution condition, and that condition is where most builders quietly break the licence.
Think of it like a stadium scoreboard. The sponsor hands it over for nothing, and the only price is that their name stays lit. Switch the sign off and the deal is gone, even though the scoreboard still works.
The licence section of the Lightweight Charts README, read on GitHub on 8 October 2026.
Verified in the browser on 8 October 2026: the Lightweight Charts repository README and NOTICE file, the Lightweight Charts API documentation for LayoutOptions, the TradingView widgets documentation, the Advanced Charts introduction, the TradingView partner rules, the Lovable pricing page read logged out, the Lovable Dev Mode documentation and the Lovable changelog. Every price and licence term below is quoted from those pages on that date.
One more thing worth knowing before you search this yourself. A search for lovable tradingview returns almost nothing useful, because a listed apparel manufacturer trades under the ticker LOVABLE and owns every result on the first page. That is why this article exists.
Lovable TradingView charts: the three routes compared
Before you type a prompt, decide which product you actually want. The decision is driven by one question: whose market data appears on the chart.
Widgets are the right answer for a marketing page, a watchlist block, a heatmap, a ticker tape or a symbol overview. You are renting TradingView's chart and their data, and you do not touch licensing or market data agreements at all. The widgets documentation lists around two dozen widgets across ten categories: charts, watchlists, tickers, heatmaps, screeners, symbol details, news, calendars, brokers and economics.
Lightweight Charts is the right answer the moment the chart has to show something TradingView does not have: your backtest equity curve, your portfolio value, a model output, a blended index, or prices from a data vendor you already pay. It draws whatever array you give it.
Advanced Charts sits between them. It is TradingView's own charting product with drawing tools, indicators and saved layouts, pointed at your data through their API. The introduction page is blunt about the trade: it is free only while the attribution stays visible and the implementation environment is public, not for private use or behind a paywall. An internal finance tool behind a login is exactly the case that falls outside those free terms.
$0 is the list price of all three routes. The real cost is the attribution you agree to display, and on one route, the market data licence you still have to buy separately.
Route one: embed a TradingView widget
This is the fastest path and the one most Lovable projects should take. You configure a widget on TradingView's site, copy the embed snippet, and tell Lovable where to put it. There is no package to install and no data contract to sign.
TradingView describes the deal plainly on its widgets page: the widgets are provided as a technology piece for free, with default TradingView branding, and the chart widget is quoted at around 35 KB. That branding is the payment. Strip the TradingView mark out of the widget and you are no longer inside the terms you accepted when you copied the code.
35 KB is what TradingView quotes for a free embeddable widget, which is smaller than most hero images on the pages that carry them.
Two practical notes for a Lovable project. First, widgets are script tags, so ask for them to be mounted in a React effect with a cleanup function, otherwise a route change in a single-page app leaves a second chart stacked under the first. Second, widgets render inside an iframe, so your own theme tokens will not reach them. Set the widget's own colour options at configuration time instead of trying to style it with CSS.
Route two: Lightweight Charts, and the attribution rule nobody reads
Lightweight Charts is open source under the Apache License, Version 2.0. That part is well understood. What gets missed is the sentence immediately after it in the repository README, which adds a condition the Apache licence itself does not contain.
"This license requires specifying TradingView as the product creator. You shall add the "attribution notice" from the NOTICE file and a link to https://www.tradingview.com/ to the page of your website or mobile application that is available to your users."
The NOTICE file in that repository is one line: Copyright (c) 2025 TradingView, Inc. with the tradingview.com address. So the obligation is concrete. The attribution text goes on the page, and a link to tradingview.com goes on the page, wherever your users can see it.
There is a shortcut, and it is the reason most people never notice the requirement. The library exposes an attributionLogo option inside LayoutOptions, described in the API documentation as displaying the TradingView attribution logo on the main chart pane. Its default value is true. Leave it alone and the chart ships the required link by itself.
The failure mode is specific and common. A designer looks at the finished chart, decides the small TradingView mark spoils the layout, and asks for it to be removed. Lovable will do it, because setting attributionLogo to false is a one-line change. At that moment the licence requirement is still live, and nothing on the page is satisfying it any more. If you turn the logo off, the NOTICE text and the link have to appear somewhere else on that page, usually the footer.
This is the single most useful instruction to put in your build prompt, because it is the thing that gets silently undone three prompts later during a styling pass.

Dev Mode is worth enabling before you start this route, so you can read the chart component rather than trusting a summary of it. The Lovable documentation is explicit that code editing in Dev Mode is available exclusively to paid users, so this is not something the Free plan will give you.
One more thing this route forces on you that widgets do not. Lightweight Charts ships no market data. You have to supply every candle yourself, which means a data provider, which means a licence. Several of the popular free tiers forbid commercial use or redisplay outright, and the terms rarely say so on the pricing page. The licence terms for the common providers are compared in detail in our guide to free stock APIs for commercial use, and that is the page to read before you pick one.
Route three: Advanced Charts, and when it is the wrong choice
Advanced Charts gives you the charting experience people recognise from TradingView itself, driven by your own data through their datafeed API. The documentation states that the library does not include market data and that you must provide your own source. The same page sets the two conditions for free use: the TradingView attribution remains visible, and the implementation environment is public.
Read that second condition carefully before you plan an internal tool around it. A finance dashboard that only logged-in staff can reach is not a public environment, and a product behind a paywall is explicitly named. If that describes what you are building, either take the Lightweight Charts route and own the rendering, or talk to TradingView first.
For most projects built with Lovable, Advanced Charts is more surface area than the job needs. The two routes above cover the realistic cases: show the market, or show your numbers.
How to ask Lovable for the chart
The prompt that works names the product, the data source and the attribution decision in the same breath. Vague prompts produce a chart with a placeholder data array and no licence handling at all.
For the widget route:
Add a TradingView Advanced Chart widget to the dashboard page for the symbol in the route parameter. Mount the script in a useEffect with a cleanup that removes the container on unmount. Do not modify the widget's own branding or its source links. Set the widget theme through its configuration object, not with CSS.
For the library route:
Install lightweight-charts and render a candlestick series from my OHLC endpoint. Keep the attributionLogo layout option at its default true. Add the NOTICE attribution line and a link to tradingview.com in the site footer as well, so the requirement survives any later change to the chart styling. Do not hardcode sample data.
The second sentence of each prompt is doing the real work. Putting the attribution requirement in the footer as well as the chart means a future styling prompt cannot remove it by accident.
If the chart is going into a wider trading view of your own, the data layer and refresh strategy are covered separately in our walkthrough of building a trading dashboard with Lovable, and the closed-trade analytics side in the trading journal build.
The affiliate rule that voids your commission
This section exists because the mistake is easy, invisible and expensive. If you are in TradingView's partner programme and you embed their widgets on the same page, there is a line in the partner rules that most people never reach.
Rule 1.15 of the TradingView partner rules reads: "Adding referral links in the widget's attribution as well as to any part of the widget's HTML code is not allowed." The same rule adds that the widget's source links should be organic and non-referral at all times.
Traffic generated that way earns nothing. The affiliate link has to live in your ordinary page copy, in a sentence a human wrote, not inside the embed snippet and not swapped into the chart's attribution link. Embedding the widgets to show the affiliation is explicitly allowed; rewriting their links is not.
One line in a rules page you probably never opened turns an entire page of widget traffic into zero commission.
Two neighbouring rules are worth knowing at the same time. Paid advertising on TradingView brand keywords is prohibited, including misspellings, and any paid campaign needs written approval first. Discounts and special offers cannot be advertised unless they are part of a site-wide promotion or TradingView has authorised them in writing. If you plan to write about TradingView plans at all, the current tier limits and prices are set out in our TradingView pricing breakdown, and you can check the live plans on TradingView's own site.
What this costs on the Lovable side
The chart itself is free on all three routes. What you pay is Lovable's own subscription, and the relevant figures were read logged out from the pricing page on 8 October 2026.
Lovable plan cards, read logged out on lovable.dev/pricing on 8 October 2026.
Free is $0 with free grants and workspace-private projects. Pro starts at $25 a month for 100 monthly credits. Business starts at $50 a month for the same 100 credits and adds the team workspace, role-based access, internal publish, personal projects, single sign-on and the Security center. Enterprise is a platform fee plus volume based pricing with no public number.
Both paid plans are credit ladders rather than flat prices. Read from the credit selector on the same page:
For a chart feature specifically, the credit question is simple. A widget embed is a small, well-defined change and usually lands inside one or two build turns. A Lightweight Charts integration with a real data endpoint, loading states and an attribution footer is a multi-turn job, and the iterations on styling are where the credits actually go. The full plan comparison and what a first build really costs are covered in our Lovable pricing guide and in the credits breakdown.
Business at $50 a month for 100 credits is the plan that matters if the chart is going into something your team publishes internally, because internal publish and single sign-on start there.
Five mistakes that break a chart build
Turning off attributionLogo during a styling pass
The most common one by a distance. The chart still works, the page looks cleaner, and the licence condition is now unmet with nothing on the page carrying it. Put the NOTICE line and the tradingview.com link in the footer on day one so this change is survivable.
Treating a widget as if you own the data
Widget data is TradingView's and arrives through their iframe. You cannot scrape values out of it, store them, or re-serve them through your own API. If you need the numbers as data rather than as a picture, you are on the Lightweight Charts route and you need a data licence.
Picking a free market data API without reading the licence
This is where a chart build turns into a compliance problem months later. Several widely used free tiers prohibit commercial use or public redisplay, and a chart on a customer-facing page is both. Check the terms before you wire the endpoint, not after.
Putting an affiliate link inside the embed code
Covered above, and worth repeating because it is silent. Nothing breaks, nothing warns you, and the commission is simply never attributed.
Using Advanced Charts behind a login
The free terms require a public implementation environment. An internal dashboard is not one. This is the route that most often needs a conversation with TradingView rather than a prompt.
Frequently asked questions
How much does it cost to use TradingView charts?
Nothing, on all three routes, provided you keep the attribution. Widgets are free with default TradingView branding. Lightweight Charts is free under Apache 2.0 with the attribution notice and link requirement. Advanced Charts is free while the attribution stays visible and the environment is public. What is not free is market data for the two library routes, which you license separately.
How do I integrate a TradingView chart into an app built with Lovable?
For a widget, configure it on TradingView's widgets documentation site, copy the embed snippet, and ask Lovable to mount it in a React effect with a cleanup function. For Lightweight Charts, ask Lovable to install the lightweight-charts package, render a series from your own endpoint, and keep the attributionLogo option at its default. Name the attribution requirement in the prompt itself.
Is there a free API for TradingView market data?
No. TradingView does not publish a public market data API, and the widgets deliver data as a rendered chart rather than as values you can read. Lightweight Charts and Advanced Charts both expect you to bring your own feed from a data vendor.
Do I have to show the TradingView logo on my chart?
On Lightweight Charts you must either leave the attributionLogo option at its default true, or put the NOTICE attribution text and a link to tradingview.com elsewhere on the same page. One or the other is required, not optional. On widgets, the default branding has to stay as shipped.
Can I use TradingView charts in a paid or private app?
Lightweight Charts, yes, under Apache 2.0 with the attribution handled. Advanced Charts, not under the free terms, which require a public implementation environment and exclude paywalled use. Widgets sit with TradingView's own terms for the widget you embed.
Does the Lovable Free plan let me edit the chart code?
No. The Lovable documentation states that code editing in Dev Mode is available exclusively to paid users. You can still build and preview a chart on Free, but reading and editing the component directly starts on Pro.
What to watch next
- v Does the attributionLogo default stay true in the next Lightweight Charts major version, or become opt-in?
- v Do the Advanced Charts free terms keep the public environment condition, which is the clause that rules out internal tools?
- v Does TradingView publish widget-specific terms separate from the partner rules, where none exist today?
- v Does Lovable add a first-party charting connector, after shipping connectors at a weekly pace through September and October 2026?
- v Do the free market data tiers tighten their redisplay clauses as more AI-built apps embed them?
Key takeaways
- Three routes, one decision: widgets show TradingView's data, Lightweight Charts and Advanced Charts show yours.
- All three are free in cash terms, and all three charge you in attribution.
- Lightweight Charts is Apache 2.0 plus a separate requirement to name TradingView and link to tradingview.com on the page.
- The attributionLogo option defaults to true and satisfies the link requirement on its own. Turning it off moves the obligation, it does not remove it.
- Never put a referral link inside widget HTML or the widget's attribution. Partner rule 1.15 makes that traffic worth nothing.
- Lightweight Charts ships no market data, so the data licence is a separate decision and a real one.
- Advanced Charts free terms require a public environment, which rules out most internal finance dashboards.
The scoreboard is still free. Just leave the sponsor's name lit, and put a copy of it in the footer in case a later redesign switches the sign off.
If you are deciding whether to build the whole thing with Lovable in the first place, the full platform assessment sits in our Lovable review, and you can compare the plans yourself before committing. Teams that want help scoping a chart or data layer can reach TJ Alam through his certified partner profile.
Start a Lovable Business workspace if the chart is going into something your team publishes internally, or book time through the partner directory first if you would rather scope the data layer before you spend a credit.
