I would like to see the same feature in backtests.
VectorVest US and VectorVest 6 have this capability and this capability is definately needed in VectorVest 7.
The survivor bias problem is in my opinion a big issue with the VectorVest historical database. My searches in the last year have found stocks that are now bankrupt. If I were to backtest now for the past year, I would get different results than those obtained at the time. I firmly beileve this needs to be fixed.
We are planning on adding these Market Timing conditions to BackTester soon.
I would also like to see more advanced money management features, such as if a portfolio max drawdown has exceeded some % then new orders would be reduced by some % amount. This would be most applicable in the auto tester.
