More confidence for investment decisions
It all started with a simple blog
We started off by creating a simple blog on Blogger, called Boersen Klaus. “Boersen Klaus” is the nick name of the private individual running this blog.
On that blog, we posted frequent (almost daily) updates on several indices, including their price and their Advanced vs. Declined data. Later the Advance Decline Line was added to all listed indices.
In addition, we started of a series of blog posts called “State of Dax”, where we would report about the health state of Germany’s well-known stock index.
During July 2021, we decided to register a domain for the blog and made it available at blog.advance-decline.net.
During the following weeks, the McClellan indicators were added and for DAX the percentage of members trading above their SMAs were included in our frequent updates.

Chart dashboarding
During July and August 2021, we started to add new chart dashboards for each index, containing various charts for market breadth. Due to automated generation, we were able to provide market breadth in better frequency.
Before that, we had to run our calculations and then make screenshots manually while browsing our dynamic data dashboards.
Website added
On August the 12th, we published our new website in addition to the small blog we already had. On this website, everyone is able to browse up-to-date market breadth data for various indices. For the first time, our visitors did no longer have to wait until we made our data available on our blog by manually posting screenshots of the data. Instead, the updated data is automatically uploaded to our website.
Envelopes indicator
After thinking about how we can add more clarity to the chart dashboards, we decided to add the Envelopes indicator on August the 29th.
From this day on, all index charting dashboards will include this indicator, and due to its nature, it will be displayed among the index price within the first chart on the top.
If you want to know more about why we chose this indicator and how we implemented it, you can read more about our decisions in this blog post here.
NIFTY indices added
We’re proud to have the most important NIFTY stock indices added to our market breadth collection on August the 28th. The stock indices from India were not part of our initial collection since the relevant data was not provided by our preferred data provider.
After a short time of development, we were able to source another provider and gather raw data which helps us to generate our own market breadth data on NIFTY 100, NIFTY 500 and co.
RSI indicator
We thought about how bring some clarity into using the breadth indicators. Being used as a filter, the RSI will play an important part and thus was added to the chart dashboards on September the 23th.
From now on, the RSI indicator will be added to all chart dashboards covering stock indices. As many active traders and investors got used to TradingView’s implementation of the RSI indicator, we decided to add exactly that version to our own dashboards. You will see that our RSI indicator is an exact copy, thus providing the exact same values.
SMA indicators
Since we’ve added the Envelopes indicator, which is based on an SMA, we decided to add the SMA 20 and SMA 200 aswell. They will be displayed together with the index in the top region of every market breadth dashboard which will be generated after September the 25th.
The SMA 20 was added so we can see the price direction for short-term time windows (does the price trade above or below). The SMA 200 was added so there is a filter to determine the general trend (upwards, downwards) and to help with trading or investment decisions.
New Crypto Index added
The 21Shares Crypto Basket Index ETP (ticker: HODL) is a popular instrument to invest in crypto currencies. This security as a WKN and ISIN and can be traded with traditional broker accounts.
The ETP covers the five biggest crypto currencies based on their market capitalization. When we added this crypto basket to our website on October the 2nd, the following five crypto currencies were covered: BitCoin, Polkadot, Ethereum, Cardana, Cosmos. As usually, we calculate the market breadth data for this index on daily basis (7 days a week).
Crypto Market Barometer published
Showing the current state of the crypto market with a sime but effective indicator – that is what we are trying to achieve by publishing our new crypto market barometer.
Coming with a new category for advance-decline.net, the crypto market barometer is supposed to gauge the crypto market and give an indication if we are in a bull or bear market.
We are planning on adding gauges and barometers for other markets as well.

Who and why
Who we are
We are not really a company or a real organization. Instead, this website is driven by a private individual who likes to explore market breadth data.
From time to time, a third-party contributes advise, data or something else to this little project.
It is clear that using the term “we” might be misleading when stating that “we” are providing free market breadth data or that “we” are working on something new.
However, it also feels natural to say “we” since other individuals contributed stuff as well, so by using “we” their work is being honored.
What advance-decline.net is
This website aims to provide free market breadth data for various stock and crypto indices. This is done by generating a market breadth charting dashboard for each index we have in our repertoire.
See this website as a free service to everyone who is interested in the health state of a stock or crypto index. And everyone is welcome to browse this data and to contribute ideas of how to make this little project even better.
Why we are doing this
The founder of this project is a private individual who is investing in index-related exchange traded products. In addition to typical saving plans, this private individual wanted to find a way to time investments and trades for improved returns.
After discovering market breadth indicators, it was clear that they provide a powerful way of timing the market, however, those tools are considered as an addition to other ways of analyzing the markets.
Still, since this private individual was already generating market breadth data, it felt natural to share the data with other people.
