I'm just getting back into business trading options and have been away from the game for a few years. I'm going to focus on some low risk calendar spreads and double diagonal strategies to start. I have been looking over what broker to work with and am assessing both their commission structure as well as their trading tools. Can anyone make a rec on a broker based on total value of both their cost as well as their offering of option trading tools. If at all possible I prefer not paying for an add on software package if a broker has a decent package. One broker who looks good is trademonster....low cost and what looks like a robust suite of software. Feedback appreciated.
