More on Hausdorff Dimension of Stock Charts
Following up my earlier post on fractional dimensions, I wrote a Python script to automate the technique. It does the measurements on various scales, runs the regression, and produces a chart. This will allow me to analyze more stocks, and … Continue reading
Fractional Dimension in Stock Charts
People often say that stock charts are fractal. Not only are there repeating patterns, but they echo across different time scales like themes in a fugue. It is a truism that you can’t tell a daily chart from an hourly … Continue reading
Stock Indicators in Python
I have been fooling around with Python as a possible tool for technical analysis. I coded a few of my favorite indicators. The GitHub link is here. Bollinger Bands Keltner Channels RSI MACD ATR ADX Stochastics I don’t think I … Continue reading
Homebrew Correlation Indicator
The CBOE index of implied correlation made the news recently, with a high of 72. This index, JCJ, is not as wellknown as the one for implied volatility, but the two are linked. Low correlation suppresses volatility, due to the … Continue reading

The purpose of this post is to explain why and how I shorted the S&P 500 on Jan. 6. In an earlier post, I described the two methods I use for detecting “tops” or, more precisely, local maxima. I also … Continue reading
Thoughts on Correlation
Mean reversion is aided by volatility, and momentum trading is aided by relative strength. I have been exploring the distribution of relative strength. Market strength and breadth are handily characterized by the mean and standard deviation of this distribution. It … Continue reading
Levy Ratio Dispersion
I have been experimenting with Levy ratio dispersion as a measure of market breadth. Saturday, I posted this chart on Stock Twits, showing lower lows, lower highs, and declining RSI for $OEXA200R. The chart shows that 87 of the S&P … Continue reading
