Introduction
This document explains how to create new static data adapters for Wealth-Lab.Net. A static data adapter allows Wealth-Lab to load, chart, and backtest historical bar/volume data. The static data adapter itself is a .Net class that derives from the StaticDataProvider base class, and resides in a .Net library assembly (dll). To build a Static Data Provider, perform the following steps: Create a Class Library project in Visual Studio that will contain one or more Static Data Adapters. Add a reference to the [...]

[...] trend change. In this case, the size of a correction wave may be taken as a factor when defining a new Wave 1: penetrations may only be considered significant if the preceding wave's extreme is broken by a multiple of the wave’s magnitude. In our opinion, this has a chance of improving overall performance of the technique in choppy markets, protecting from changing direction too soon. On a closing note, the companion SVEHLZZperc indicator has been added to TASCIndicators library. Conceptually, it's a variation of the well-known trailing reverse method with a twist [...]

We’ve included a trading strategy that shorts on “Oscillator lower-top divergence” and exits after a specified number of bars, which can readily be changed using the parameter sliders in the lower-left corner.
