Remember eSignal v10.6? The last build was August 22, 2011. That's four years ago and that's where you have to go if you want to use the simulated real-time features of Tick Replay Mode. That mode allowed you to properly back test a trading strategy. Unless I've missed some nook or cranny in all subsequent releases, such testing has not since been possible and can only be approximated with bar-interval prices. This is especially frustrating because, from a programming point of view, it would seem to be an extremely simple and minor extension of what eSignal does normally – just using a different data stream. Am I the only one who mourns the loss of this very useful application? Any chance it will return?
