New High/Low Accumulation Index
Indicator Type: Standalone
Chart Type: Interactive Charts Only
The New High Low Accumulation Index is designed to confirm bull markets and identify major stock market bottoms. It is described in detail in the e-book The New High – New Low Index by Dr Alexander Elder and Kerry Lovvorn.
The index is based on the Barchart 52-Week High-Low Index $MADX which calculates the difference between the number of common stocks making a new 52-Week High and new 52-Week Low during the current trading session. The $MADXindex encompasses around 4,500 stocks each day. The New High Low Accumulation Index for each day is calculated by summing up the Barchart 52-Week High-Low Index for the past five trading days, creating a weekly plot.
The New High Low Accumulation Index rises above +1,000 only during major bull markets, where it confirms them. It falls below the -4,000 level only at major stock market bottoms, which occur a few times in each decade. When this index falls below -4,000 and then rises above that level, it gives one of the strongest buy signals in technical analysis.
The New High Low Accumulation Index can also be viewed using the Barchart 52-Week High-Low Market Cap Index which calculates based on the differential of the Market Capitalization of Stocks making a new high and new low using Barchart symbol $FADX.

On the chart below of the S&P 500, the New High Low Accumulation Index reversal from the low signaled the market bottom in Dec 2018, as well as March 2020. In more recent times, while the rally from the low in May 2022 was short lived, the September 2022 reversal below the -4,000 point was within a couple of weeks of the market low before the market rallied again.
