Hello, I need your help to choose a better broker for fast execution. I tested three 1 minute charts today, Ninja-Zenfire with Mirus, Ninja-IB, and TOS with Thinkorswim, the 1-minute bars are updating almost at the same time, to my eyes. I am confused that why everyone said Ninja-Zenfire is faster than TOS? How to judge on platform and data feed? Let's not talk about commissions, that is why I just closed my account with Thinkorswim. Any comments will be welcome. Thank you so much.
