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 [...]

The reason is that when Wealth-Lab determines the number of shares for an order, it does so with regard to the so called "basis price". For the whys and wherefores of it and specifically how this can cause skipped trades with trade sizes near 100% equity, refer to the User Guide: Strategy Window > Backtesting Strategies > 100% of Equity Sizing .

Speeds up optimizations. Optimal parameters are usually discovered in a fraction of time it takes when using exhaustive search. Works where exhaustive method stumbles: when the number of parameter combinations is too large. It takes only a subset of total runs to find the "Top-10" of values using Particle Swarm Optimization (PSO). In this document, “PSO” may be used as a shorthand for “Particle Swarm Optimization.” Aims at the near optimal solution which is likely to be a [...]

Works where exhaustive method stumbles: when the number of parameter combinations is too large. It takes only a subset of total runs to find the "Top-10" of values using genetic algorithm. Aims at the near optimal solution which is likely to be a robust solution. The genetic algorithm does not seek for the absolute optimum which could easily turn an unreliable [...]

Background
If you can express a trading system in words, then you can almost certainly program it with WealthScript. Unlike most other analytical trading tools, WealthScript doesn't hide the trading system loop from the programmer and largely for this reason you can design systems in Wealth-Lab that could not even be realized on other platforms. The programming power of WealthScript can overwhelm at first, and we tend to see the same questions when it comes to adding rather simple new methods or conditions to

Using Automated Exits (AutoStops) in WealthScript
The WealthScript language contains a number of functions that can help you program various types of automated exits in your trading systems. All of these exits could also be programmed manually, however the automated exits can be used as a way to reduce the size of your code. If you wish to implement exit rules that go beyond what the automated exits offer, you can code these manually using WealthScript Trading System functions.

The data returned by your data vendor are stored by the data provider, and when you turn on Market Manager support for it, [...]

Traders' Tip text
Detecting swings is a range of popular techniques among traders. While the article by Domenico D'Errico throws light on some more creative approaches to the problem, let's start with the definition of the commonly recognized one. As given in the text ( “the previous bar's low is lower than the previous two bars and the current bar's low” ), a pivot high/low point is different from the more traditional one which is more like “1-2 consecutive lower lows followed by 1-2 consecutive higher lows”. Further, text and code [...]
