In this episode David shares research into the effectiveness of indicators to identify Bull and Bear markets; he’s tested a large number of indicators and combinations with some interesting results!

Topics discussed What the popular Golden and Death Cross can tell us about the probability of a Bull or Bear market Using the RSI indicator to determine market state Methods to reduce the lag the 50/200 Moving Average crossover experiences Using ADX and Price Variance to identify Bull and Bear markets Creating indicators based on the value of other indicators Modifying the McClelland Summation Index indicator to identify market states How datamining increases the chance of good luck in the results Why the White's Reality Check and Monte Carlo Permutation methods breakdown using certain data-mining approaches How the role of Technical Analysis could change over the next 10 years New developments in Machine Learning which may see the end of the role of technicians   Disclaimer: Trading in the financial markets involves a substantial risk of loss and is not suitable for everyone.
