Backtesting Engine Definition
TradeStation Backtesting Engine At Work
The Backtesting Engine is the core software doing the backtest.
It takes as inputs the historical price data and trading strategies.
The backtesting engine applies the trading strategies to the historical price data to get a series of hypothetical trades and records the results.
The outputs of the backtesting engine are typically performance statistics. I have added instrumentation to gather additional information about each trade for later analysis.
Many backtesting engines are available commerically. Well-known platforms include TradeStation, Worden Blocks BackScanner, WeathLab, Amibroker. Many brokers such as TD Ameritrade offer backtesting engines for their customers.
In spite of the wide availability of software, many traders don’t backtest because of the huge amount of work it takes. Reading a Backtesting Report is much easier.
