Check out the new article: Reimagining Classic Strategies (Part 19): Deep Dive Into Moving Average Crossovers.
This article revisits the classic moving average crossover strategy and examines why it often fails in noisy, fast-moving markets. It presents five alternative filtering methods designed to strengthen signal quality and remove weak or unprofitable trades. The discussion highlights how statistical models can learn and correct the errors that human intuition and traditional rules miss. Readers leave with a clearer understanding of how to modernize an outdated strategy and of the pitfalls of relying solely on metrics like RMSE in financial modeling.
This article explores the classical moving average crossover strategy and offers the reader multiple alternative solution paths they could follow to overcome the conventional problems of the strategy. Among many other well-known issues, the strategy is known to be noisy, to give delayed trading signals, and to be widely exploited. In simpler terms, this means that the trading signals given by the traditional moving average crossover strategy can be reversed too quickly and too frequently for traders to reliably profit from the strategy. Additionally, many false breakouts trigger early entries.
The strategy, in its traditional form, appears to be susceptible to noise and has unreliable mechanisms for filtering out weak and unprofitable trades. The solutions we present here help to overcome the weaknesses of the traditional strategy by building filters for trading signals that are far more robust to market noise. In particular, in this article, we explore five different variations of solutions aimed at filtering the weak trades out of the signals generated by the crossovers.
The moving average crossovers appear to be fertile ground for our statistical models to learn from. The statistical models we built learned the error that remained in the moving average crossovers—error that we were unable to manually filter out ourselves by creatively thinking of better trading rules. There is obviously a natural limit to how far our human intuition can guide us in optimizing a strategy, but where intuition falls short, our statistical models can help us pick up the rest of the work to be done.
