Greetings, So I see Tradestation is now at version 9.1 with a new feature called Portfolio Maestro. It appears to allow portfolio level back testing. https://www.tradestation.com/trading-technology/whats-new/tradestation-9-1/base/portfolio-maestro I haven't played with it yet. Maybe this is what we've been waiting for - the ability to work money management rules into our various noncorrelated systemz across a portfolio of equity curves. I keep reading that money management is the secret to system trading, and the pros always run a huge variety of markets, some with discreet systems for each. Anyone tried it yet?
