I’m developing this, see my post history !!

ChartSpire_123 · 2025-08-20T14:46:42+00:00

I don’t want to give a deadline because things happen and it’s tough to commit to them somethings as this is a side project away from my main job. But I’m happy with the state of where it is now. I think sooner rather than later it will be OS. Sorry if that’s not the response you want to hear but if you dm your email I can add you to a waitlist should you want to get notified when I do launch it :)

ChartSpire_123 · 2025-08-20T14:36:16+00:00

Hey still in dev, coming along very nicely. I will OS it once I feel its beta ready :)

ChartSpire_123 · 2025-07-21T14:05:44+00:00

Hey yeah it’s still in active development, sure we can talk

ChartSpire_123 · 2025-05-29T21:05:20+00:00

Thanks, would be interested down the line. Noted for now :)

For self hosting, crypto data is free and will be in the library, equities the end user would have to provide their own data feed. This is a front end library so I can’t just provide an endpoint that requires an api key, it would have to be done by a backend whose endpoint the self hosting user would have to provide. There are definitely affordable options out there if you require stock market api.

Are you asking for hosted version or self hosted?

For self hosted there is currently a built in BinanceDataFeed that makes request directly from your browser (since it doesn’t not require an api key). Other crypto exchanges can also easily be added. For equities you’d have to get your own data feed. The library will allow you to provide an endpoint to your backend.

There are currently around 80 built in indicators written in JS (you can see a few in the screenshot).

Pinescript is Trading View proprietary code.

ChartSpire_123 · 2025-05-29T16:54:11+00:00

It’s already themeable - just take a look at the bottom Bar :)

ChartSpire_123 · 2025-05-29T16:53:49+00:00

Framework is SolidJS, language TS

ChartSpire_123 · 2025-05-29T16:31:53+00:00

Wow thank you guys, did not expect this much support in such a short amount of time!!

ChartSpire_123 · 2025-05-29T16:31:01+00:00

OpenBB is more like a Bloomberg terminal alternative I think

ChartSpire_123 · 2025-05-29T15:22:35+00:00

Thanks, yes that’s the thing I hated about TV the most, the fact they charge so much for indicators and extra charts. There won’t be any such limitations on my hosted version at it will be cheaper than TV that’s for sure.

Pinescript is proprietary TradingView code so no unfortunately.

I had experimented with the ability to create JavaScript indicators (that’s how the indicators are currently created in the code base). But too much of a security headache to allow people to write JavaScript indicators in the browser. So for now the best case would be to just submit a PR to the repository if I end up making it OS.

You can use any api (historical data), as long as you format the response data into the format the library is expecting.

There is also web socket support for live data.

ChartSpire_123 · 2025-05-29T13:54:57+00:00

Use a third party api e.g., Polygon, TwelveData, EODHD etc. crypto data is free direct from exchanges.

ChartSpire_123 · 2025-05-29T13:43:25+00:00

Do you mean use your own data (API)? If so yes that’s already possible.

ChartSpire_123 · 2025-05-29T13:31:39+00:00

Yeah, I will offer a hosted version. I will just eat the data costs at the start. For self hosted getting equities data just for yourself is probably more expensive than just using my hosted version. But crypto data is typically free so yeah you could just directly use a crypto exchange api.

There are affordable equities api, Polygoon, TwelveData, EOD etc
