Come on, you should give other options traders a bit more credit than that --or at least a bit more of them. ;-) How many options traders are there? I mean traders that are not using options as an equivalent to the underlying for leverage. I would think this group would represent a bigger...

Yes, I was wondering the same myself. Why aren't they listed in ET's rating list? I would like to know if they charge for canceling orders options orders like IB. IB's fee structure is bit complicated. Plus, their customer service is notorious. I am still deciding between thinkorswim and...

I don't know what this strategy is called, but I think this is probably similar to a short iron butterfly. I wanted to find a way to hedge a collar and I ended up with something like a short iron butterfly. Here is my thought process: Standard collar: Long stock + ATM long put + higher...
