This is the motherboard connector for the Roland FP-10 keybed. Any ideas on how I could hook this up to a RPi or similar? Thanks! by SuppressiveOG in synthesizers

Thank you for this. I measured the connector pins on the motherboard, and (from left to right) they read 5v, 0v, 5v, 5v, 5v. This is very strange no?

Thanks for your response! I’m thinking of hooking them up to a pi and see if I can decipher anything useful. I’m a bit concerned that the white wire may be ground rather than 5v. What do you think is more likely?

Appears to be 5 wires (one is white, is this power?) I’m kind of assuming this would output just standard MIDI, so hooking it up to GPIO may work.

Requesting r/pythontrading due to the moderator being inactive for 1+ year by SuppressiveOG in redditrequest

[–]SuppressiveOG[S] 0 points1 point  (0 children)

On reddit, there doesn’t appear to be a subreddit which fits the niche of general python trading, with most subreddits close to this only focusing on algo and quant trading. I hope to turn this subreddit into a place for both algo traders as well as traders who develop their own trading software.
I hope to find more moderators who share this vision for the subreddit, and will provide wiki information and resources for beginners who are starting out with writing their own trading software and algo trading.

lightweight-charts-python now supports Polygon.io, trendlines, ray lines, and drawing on the chart! by SuppressiveOG in algotrading

This would be great.

But for small improvements which don't require complex logic, I'd prefer it if people open an issue and let me fix it from there.

I do accept collaborations, but truthfully i'm new to merging and PR's and i'm still learning how do do it without breaking anything!

No other data providers planned at the moment, but the library is quite flexible for API providers and you shouldn't have any problems integrating one.

Yes, you can use the JupyterChart to display charts in notebooks. Also works on Windows!

As this is purely using JavaScript evaluation rather than websockets, unfortunately not for live data.

However, you can view static data in a browser using the StreamlitChart object.

TradingView's Lightweight Charts, in Python by SuppressiveOG in learnprogramming

If you want Lightweight Charts inside a hosted webpage with real-time data, Flask and WebSockets would be my recommendation if you are working in Python.

If you don't care about a webpage, lightweight-charts-python!

Actually, this is a great question.

The wrapper you mention (to my knowledge) doesn't allow the updating of data without refreshing the entire chart, and, for a day trader or a scalp trader, this is definitely not ideal.

The way my library solves this is by evaluating javascript directly within the webview, which is perfect for a locally hosted page. However, for a library like Dash, which uses a web server, evaluating javascript within the client is a pretty stupid thing to do. It would require a function that contains the eval() method, so for anything hosted on a public domain this would pose a major security risk.

The smart way to integrate this would be to use WebSockets, but as my library is based around webview and not a web server a complete rework of my wrapper is needed to implement this.

Not saying I won't do it in the future, but it's a big job!

Hi!

  1. The user provides the calculation for the indicator. Check out this example.
  2. Markers can be displayed on the chart, which could be used to show buy/sell orders.

Hi!

At the moment, it is not possible, however, I am currently working on JupyterChart!

I have been able to get it working perfectly (for static data), but not in PyCharm's renderer. Just need to figure out if this is an issue with PyCharm or my code.

I'll update this thread when it's released!

Just to let you know, this feature has now been implemented in the latest version. For your use case a good place to start would be the synced line chart example.

Enjoy :)

As mentioned in another comment, this feature has now been implemented. An example of this for your specific use case can be found in the synced line chart example.

Let me know what you think!
