Combine trading is a great chance for someone that can write a program but does not have the personal funds to trade their own account to prove themselves. TopstepTrader charges a fee to trade in there combine. This makes me think that is how they make their money charging for the combines. Are there any other companies that offer a trader combine so they can prove themselves? I think this is a great idea and the company then knows whether they have a golden egg or just an egg. I am seeking trader combine, I have develop such a program. Thanks For any positive post.
