I've been using EFS for some time and what irritates me a great deal about this platform is how to index and find data based on time. For example, there's no real way to make a simple function call to retrieve the closest tick after an arbitrary point in time on some day. What I'm looking for is a reasonably priced solution that allows me to backtest and study the performance of models [at the tick level], but makes it exceptionally easy for me to work with time. I have been writing C++ software for 10 years, but I do not want to leave the comfort of a high level alnguage to engineer data structures to maintain and deal with time. I want my platform [like e-Signal] to give me high-level functionality like this. It's what I feel like I paid for. Can someone paste some sample code from their respective platform for, say, retrieving the closest quote or OHLC price for a given bar at some arbitrary point in history? I am really getting frustrated with how little e-Signal and EFS provides me.
