I am a full time options trader. This is how I earn my living, as such I clearly am not "thinking small" nor am I a "newbie" as I have been trading options for over ten years. Your constant closed minded stance to any other broker besides IB does nothing to further this discussion. I traded with IB for five years, have you ever traded with Tradier? The answer is no and therefore you are in no position to compare the two. After trading with both (as well as OptionsXpress, TOS, Lightspeed and Options House) I am able to make comparisons based upon experience not closed minded speculation. That experience when taking into consideration cost, technology and execution reveals that Tradier is by far the superior offering for US residents that trade a high volume of option contracts. Increasing one's returns by as much as 20% per year is a distinct possibility for the high volume/professional trader. This is the exact opposite of "thinking small."
