I used to be a skeptic too. On terms of confidentiality, I am privy to some of the shorting tactics used by traders I have met who trade with firms in and around Toronto. I have come to learn that they are aware of many senior and experienced people who SHOULD know, who are of the notion that MMs dont "play games" as much as ppl like to believe, and they (the traders) are not in a hurry to change that notion. More goes on than you realize. This board is my first experience wherein it's contributors may have actually and properly disected a series of transactions that while legal, are not easily discerned. It's quite another to catch the shady stuff.
Hats off guys.
