Wealth Lab
Wealth Lab is a technical analysis software as well as an electronic trading platform owned by Fidelity Investments. It was created by Dion Kurczek, who founded the original Wealth-Lab, Inc. corporation in 2000. Fidelity acquired the Wealth-Lab software assets in 2004. The client runs on Microsoft Windows .NET Framework v4.0 and requires internet access to function properly. Licensed users can program and backtest trading strategies for stocks and futures. Fidelity premium account holders can use the platform to place trades produced by their trading strategies directly to their brokerage accounts and even setup auto-trading systems. Software
Wealth-Lab has an integrated programming environment based on C# syntax with added versatility derived from using its own pascal-like programming language, Wealthscript. Although it is geared toward programmers, it has a drag & drop feature that allows non-programmers to create their own trading strategies based on technical analysis without the necessity to edit or even view any source code. This ability to custom build trading strategies by dragging & dropping basic entry and exit modes and their indicators, not only allows non-programmers to create and use strategy scripts, it expedites the process of programming for both experienced and novice developers. Wealth-Lab requires Market data in order to perform the majority of its operations. In its standard installation, several market data sources are provided such as Yahoo! Finance's free End Of Day data. Users can also lease real-time market data from reputable sources such as Commodity System Inc. Displaying the market data in meaningful ways, i.e. charting, is one of the user's primary activity. Wealth-Lab displays market data in all the typical formats, namely, candlesticks, line, and OHLC; and even the non-typical formats such as kagi chart, Renko, equicandle to name a few. It also allows users to simply drag & drop one or more indicators, from its vast library, right onto a chart subsequently creating panels and annotations for each indicator. In addition to standard technical analysis indicators, users will also find a substantial amount of fundamental analysis indicators to apply to their charts. Backtesting strategies is at the heart of Wealth-Lab. User can either "Explore & Backtest" or "Build & Backtest". ´Build´ refers to the drag & drop method of strategy creation where as ´Explore´ refers to prebuilt strategies that are pre-installed or can be downloaded from the support website, Wealth-Lab.com managed by WL Systems, Inc.. The advantage of the prebuilt strategies is the ability to optimize the parameters. The installation comes with two optimization methods: exhaustive or Monte Carlo which uses a unique method of employing random numbers to create simulations. There are many more Wealth-Lab optimizers that can be installed from Wealth-Lab's extension manager. Developers can also program and share their own indicators, optimizers and strategy scripts, and it has been this open platform philosophy that has contributed to the establishment of a supportive developer's community. Client availability
Wealth-Lab 7 is available by subscription to customers worldwide without exception, including U.S. and Canada. Version 6
Prior to August 2020, two legacy versions of Wealth-Lab existed. Wealth-Lab "Pro" was available to Fidelity premium account holders in the US (only).

The backtesting engine was overhauled to process bar-by-bar, which allows strategies to dynamically access and interact with the equity curve and other simulation aspects. Automated strategy trading is possible by installing extensions for one or more brokerages.
