Hi everyone, Does anyone out there have any recommendations for a quality backtesting software package? I don't need any fancy charts etc. It just needs to provide an interface which allows me to replay market data (both L1 and L2) to my strategy and handle generated orders, produce execution reports etc etc. You know, all the usual stuff. Would also be advantageous if the fill logic could be customised to allow for both optimistic and pessimistic scenarios to be evaluated. Been using the market replay functionality in Ninja up until now but have become really fed up with the limitations that their order management logic imposes. I know NT7 is supposed to allow overriding of the order management logic but I can't see that being released before 2020. Plus, I hate the Ninja API more than words can express. Any thoughts? Thanks in advance.
