Different Results between Backtesting and Live Testing

05-02-2007, 02:16 PM

Do you have the same problem as mine?

Even when I use the same data set, same range, same setup, same strategy, the signals that I got from Backtesting and Live Testing are not the same.

Anyone know why is there the difference?

You can't expect results from a backtest to be the same in real-time, even if you are using the same data set. There are many variables. One is the order simulation in real-time is vastly different than the backtest order fill algorithm.
