How to Estimate the Efficient Price with a Kalman Filter (Market Noise Model) — Python Solution
Market prices are noisy. The “efficient price” is the hidden signal behind the noise.
This post shows how to model price + noise with a Kalman Filter and implement it in Python (step-by-step).

Vielen Dank für die Infos.
Allerdings stellt sich mir die Frage, leider immer wieder, warum Signal als Alternative für WhatsApp angegeben wird - m.E. unterliegt auch Signal den "Datenschutz"-Regeln der USA und damit nicht den europäischen Datenschutz-Regeln.
Darüber hinaus gibt es inzwischen viele europäische alternative Angebote zu WhatsApp, Google, ....
Wo?
Hier: https://european-alternatives.eu/de 👍

Meine bevorzugten Alternativen sind:

#ginlo2 (statt WhatsApp)
https://www.ginlo.net/downloads/

#Quant (statt Google)
https://www.qwant.com

diverse Online- und Offline-Shops, z.B. Buchladen vor Ort, OTTO

#Firefox (statt Chrome)

#mastodon statt (#X, #Facebook, #Instagram) 😉

Und mein Handy ist natürlich ein Fairphone - mit franz. Betriebssystem.

Als nächstes ist dann wohl Linux dran...

I am moving on with my #Quant Terminal also with xterm.js and Sixel as well as ANSI support.

* full data-qualification pipeline with fat fingers and outlier filter from Yfinance and FMP
* Dollar / Volume and Tick Bars
* HMM ML for market regime detection (using CUSUM and micro-structure analysis)
* Macros for every asset with charting parameters
* Seaonality analysis (10y cycles and inner trends)
* COT data analysis
* Hamilton node architecture (can also be used in Jupyter NBs
* next: Wavelets and FFTs for sideways markets

Adding (r)DCF valuation and alternative data RAG for sentiment analysis next.

I also added a REST API to export the data to PowerBI, but I think PowerBI is developed by fancy fancy people.

"Semantic model" == dataset? I think it's like in these fancy Manhattan restaurants where they invent names for common vegetables.
