US and EU stock indices data ingestion currently broken

An update on data ingestion and chart generation Here is a real quick update on what can currently be observed on the main website: Our main data source for US and EU stock indices changed some internals, which is why the automated data ingestion no longer works. Hence, the automatically generated charts stopped updating in June. Unfortunately we noticed very late, and now the charts for the US and EU stock indices are outdated. The charts for indices from India and all crypto-related things are not affected. What are the next steps to fix the US and EU stock indices charts? We are going to look for another data source and adapt all things accordingly. We will let you know as soon as everything is fixed.    

Advance Decline Line for S&P500 and more Market Breadth Indicators

Advance Decline Line for S&P500 and more Market Breadth Indicators

With this blog post I just wanted to give you a small heads up for our new website which provides a bunch of market breadth indicators for many indices, including the S&P500

On our little indicator dashboard, we currently provide:

  • Historical data for S&P 500
  • Advance Decline Line for S&P 500
  • Advanced vs. Declined for S&P 500
  • McClellan Oscillator for S&P 500
  • McClellan Summation Index for S&P 500

The strong development of the S&P500 during the last trading days was undermined by market breadth data, which usually means that the ongoing trend is stable and healthy. However, we all know that there are also many tech stocks among the S&P500 components, and they've been struggling with various challenges lately (despite the good earnings season).

This makes the S&P500 somewhat vulnerable. Just make sure you thrown an eye on our market breadth data for the S&P500 so you always know about the index health state.

Dow Jones and NASDAQ 100 also available

Surely you know that we also provide market breadth data for the Dow Jones index and the Nasdaq 100 Index. Market breadth usually helps to see the bigger picture behind the "normal" price development.

By the way: If you check out our latest market breadth visualization on Nasdaq 100, you can see the the McClellan Summation Index declined six trading days in a row, reaching a value of more than -15:


This indicator alone should not be used for making trading or investment decisions, but maybe it will help you to understand the current state of the Nasdaq 100.
