Traders' Tip text
To test the efficiency of the four indicators in detecting trends, we present a framework which lets a Wealth-Lab user run any of the four example systems. By dragging respective "parameter slider" on the bottom left of the screen, either one of the included subsystems will be executed (ADX, R2, VHF or ER) or all together.
While most indicators used by Mark Katsanos are prepackaged, one participating indicator – Kaufman's
Efficiency Ratio – has been included in the
Community Indicators library which should be installed additionally from our website's
Extensions section.
Figure 1 illustrates trades taken by all the four trading systems at the same time on the Daily chart of USO (U.S. Oil Fund).using System;
