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 Unfortunately we noticed very late, and now the charts for the US and EU stock indices are outdated.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.    

18th August 2021 S&P500 Dow Jones Nasdaq 100 Market Breadth


Fed minutes causing drops in major US indices

Today's published Fed minutes indicate that there are thoughts about ending the money flood this year instead of next year or the year after. This led to a small sell off.
Now, market breadth data - including today's trading day - is interesting.
All three major US indices that are listed below - the S&p 500, the Dow Jones and the NASDAQ 100 - reached extreme values for their Advanced vs. Declined data.
Usually, if such an extreme is reached, there is at least a small reaction in the opposite direction.
It will be interesting to see on Thursday if the markets realize that today's news weren't so bad at all. Will the markets calm down tomorrow?



S&P 500


For S&P 500, the McClellan Summation Index is still in a good place. The short-term indicator McClellan Oscillator, however, is negative the second day in a row.

Dow Jones

The Dow Jones McClellan Oscillator has a negative value again, after being positive for 8 subsequent trading days. The McClellan Oscillator is still positive, but is also not so far away from the zero line.

For Nasdaq 100, the McClellan indicators show an ongoing negative trend. Will this development continue since the Fed minutes were actually bad news for the tech sector?
