Trend following is based on the thresholds called P&Q which is calculated from the amount of an uptrend and downtrend to determine when to...

Many variations and modifications were made upon VFDT since it was first introduced in year 2000. Novel contributions were mainly made in two aspects of VFDT, tree induction process and prediction process,...
