For this post, I want to take a look at the concept of intra-day momentum and investigate whether we are able to identify any positive signs of such a phenomenon occurring across (quite a large) universe of NYSE stocks. It has been suggested that, for the wider market in general at least, there is a statistically significant intra-day momentum effect…

In this blog post I wanted to run a couple of quick experiments to see how clearly I was able to highlight the importance of incorporating various elements and components into a backtest that I admittedly often overlook in most of my posts – that is I make the assumption that they will be dealt with by the reader at…

In this article I wanted to concentrate on some basic time series analysis, and on efforts to see if there is any simple way we can improve our prediction skills and abilities in order to produce more accurate results. When considering most financial asset price time series you would be forgiven for concluding that, at various time frames (some longer,…

I thought today I would whip up a quick post regarding Jupyter Notebooks and how to download, install and use various “addons” that I like using and find more than just a little bit useful. Among other things I’ll show how to use the “jupyter-themes” module to change and manipulate the basic theme and styling of the overall notebook, I’ll…

In this post I am going to be looking at portfolio optimisation methods, touching on both the use of Monte Carlo, “brute force” style optimisation and then the use of Scipy’s “optimize” function for “minimizing (or maximizing) objective functions, possibly subject to constraints”, as it states in the official docs (https://docs.scipy.org/doc/scipy/reference/optimize.html). I have to apologise at this point for my…

This is part 2 of the Ichimoku Strategy creation and backtest – with part 1 having dealt with the calculation and creation of the individual Ichimoku elements (which can be found here), we now move onto creating the actual trading strategy logic and subsequent backtest. The Ichimoku approach concerns itself with two major elements – firstly the signals and insights…

I thought it was about time for another blog post, and this time I have decided to take a look at the “Ichimoku Kinko Hyo” trading strategy, or just “Ichimoku” strategy for short. The Ichimoku system is a Japanese charting and technical analysis method and was published in 1969 by a reporter in Japan. I thought I would spend this…

In this article I thought I would take a look at and compare the concepts of “Monte Carlo analysis” and “Bootstrapping” in relation to simulating returns series and generating corresponding confidence intervals as to a portfolio’s potential risks and rewards. Both methods are used to generate simulated price paths for a given asset, or portfolio of assets but they use…

This blog post is a result of a request I received on the website Facebook group page from a follower who asked me to analyse/play around with a csv data file he had provided. The request was to use Pandas to wrangle the data and perform some filtering and aggregation, with the view to plot the resulting figures using Matplotlib.…
