A terminal stock watcher and stock position tracker

Great work! I see that you're using Yahoo Finance data. Yahoo deprecated its API so your data could stop flowing at any time. You can try free services like Alpha Vantage [0] or Google Finance formulas in Google Sheets exposed as an CSV / JSON. Another way is to hook up a freemium service like IEX [1] and ask your users to BYOK - bring your own key. I use IEX for my stock watching browser extension [2] and eat the costs for my users. It's not too bad.

An alternative way is to monitor the data and extract it from the Yahoo Finance website itself (or another one for the matter).

We solve this at Monitoro[0] and we make it easy to receive alerts or just store historical prices in SaaS apps and automation platforms. No fear of losing access to the API, and no need for coding in the first place.

I think your service is super helpful for many small volume use cases! But it doesn't come with guarantees right? Like if Yahoo moves its UI around, change elements and classes, etc.

not yet, but you will be notified that extraction has stopped, and you can fix it in a few seconds.

We want to make it eventually robust to changes unless the data was really removed from the webpage you’re monitoring.

Show don't tell right?

Here's a Euronext tracker built on Airtable and Monitoro. It can also send notifications on Slack/Discord/...

Have you considered charging for your extension? I just made https://extensionpay.com which makes it easy to add payments in your extension without needing to run your own server.

I have! This is timely because Chrome Web Store just killed its payment system. How does this compare to using Stripe out of the box?

BTW I think someone was trying to start a browser extension developer guild on HN, can't remember which thread... You should tap into that community.

Basically you don't need to run your own server / database / custom Stripe integration code / user management system / custom extension integration, which is annoying to write yourself and costs money to run a server. With ExtensionPay you just add a little code in your extension [open source here](https://github.com/Glench/ExtPay) and register your extension in the web UI. I made it for use in my own extensions :)

Cool, I'll check it out, thanks. Any other hints to how I could find it?

That makes sense, I'd try it before rolling my own. If I do charge, it'll be a recurring subscription.

I found it! Look at the end of this post. I submitted the form but didn't hear back though. If you find anything let me know, I'd love to connect with fellow extension builders.

Great! I'm working on adding subscriptions now. And thanks for the guild link!

Isn't AlphaVantage free limited to 5 requests a minute and 500 a day? And it requires an API key?

I think it's a soft limit? I haven't run into the limit, but then it's not my primary data vendor. Just ask them and they'll give you an API key for free.

I have api key, but I obeyed the (low) limits when I used it. I heard a lot of recommendations for it, but was surprised with the free tier limit.
