Evaluating Your System


Start testing your system by running python command:

python path/to/trading_system.py

The only requirement is to have the following at the end of your python file to make the trading system file self-executable.

# Evaluate trading system defined in current file.
if __name__ == '__main__':
        import quantiacsToolbox
        results = quantiacsToolbox.runts(__file__)

Alternatively, you can always run the trading system straight from Python console:

> import quantiacsToolbox

> returnDict = quantiacsToolbox.runts('/Path/to/your/TradingSystem.py')

Trading Results

runts loads the market data and calls your trading system for each day of the backtest with the most recent market data. It simulates the equity curve for your output values p. The toolbox will return a dictionary of performance values and a plot of your system’s performance.
