Based on what you have been trading, you'd pay $85 in data fees per month if you go live with them. That's because you get put in the professional trader category when trading for a prop firm. It is definitely something to consider, but if you trade like you did in the combine, it shouldn't be much of an issue. I like trading a wide variety of instruments, so it would be more of an issue to me because of the scaling plan that they have which limits how many contracts you can have on at once.
Yup, I was talking to an experienced trader about that the other day. It does suck but I guess it's the price to pay for getting the TST platform. Still have to get past funded trader prep but if i do pass I think i'll try to trade the funded account hence I would have to eat the cost. At this point i'm just trying to learn and get comfortable with trading though and I do feel somewhat comfortable with the limited exposure that TST offers
