Roberto perhaps described it incorrectly. You can get 200K by signing up for an IG account via ProRealTime but you must meet certain trade amounts to maintain it.
v11 will have the ability to provide much larger amounts of back test data but how much you get based on whether you have an IG direct account, a PRT account or are basic or premium or whatever levels PRT and your broker decide upon we will all just have to wait and see.
At the moment we just have to wait to see what is available and to who.
