Hi All,

I've been running a live algo on the QC environment since Oct 23 2019.

It's current equity curve looks like this:

However, when I now backtest the very same code. I get an equity curve like this:

The code is identical, bar a SetStartDate parameter to align with the live start date. I did not have this issue with any previous backtesting, as recently as 3 weeks ago. 

Has QC recently changed it's C# backtesting engine? Any help would be greatly appreciated.
