Nobody will tell you about the platform itself because those are closely guarded secrets. A more specific description of the problem might help though. There's a huge amount of data in many forms, a huge amount of unpredictable major events, a lot of noise, a lot of hidden data (take hidden orders on exchanges as an example), and any action you take is going to affect the market. If you do something dumb, like place a bad order , nobody would take it in simulation but they would in real life. This makes it extremely difficult to understand why your model performed the way it did, what needs to be fixed, what sort of risk it entails, etc. Research platforms help answer these questions without quants having to do do complex bespoke analysis over and over again.
