Sigma-L: Expert Market Cycles Insight

A major market top forms in Bitcoin (BTCUSD), back in April 2021. The use of VTLs and FLDs to confirm price peaks and troughs form one of the tools we use frequently in Hurst Cycle analysis.

Sigma-L brings the power of signal processing and Hurst Cycles to traders/investors in a new way. Expect a compact yet comprehensive email newsletter and website format, penned by an expert in the application of this wonderful technique and modern signal processing.

Originally proposed by pioneering engineer JM Hurst in the 1960s and 1970s, Hurst Cycles are often bewildering for the average investor/trader. Although an attempt was made by Hurst himself to simplify the techniques to a totally practical level in the now rare Cyclitec Cycles Course, many new and enthusiastic students are often disconcerted with the mathematical foundation at the heart of this approach.

Today, innovations in software and signal processing techniques would have amazed Hurst, allowing a huge range of markets to be subjected to this kind of time-series analysis.

Hurst Cycles allow the investor or trader to leverage the predictive power of periodic functions present in financial markets and setup the entrance to a more general understanding of signal processing. Hurst Cycles are completely unique in approach and comprise a robust set of action signals, risk management and price action methodology. The edge a trader or general investor can gain from a deep knowledge of this technique will be indispensable.

Here the remarkable cyclicality of the VIX volatility index is highlighted with a wonderful component around 68 days present, amongst others. This kind of visualisation can help identify periodic functions in markets and their relationships to each other over time.
