Hi Fellas, Hoping there are a few guys gracious enough to take the time to answer or at least point me to where I can learn. Tried searching on my own, and there is not a lot out there. Last week there was a huge down move (5 or 6 big figs) in some of the Yen crosses around nine in the morning. I caught a few comments about large funds supporting the market due to some large "knockout' options that were expiring. Not having an institutional background, I don't really understand this kind of stuff. Where could I go online or what books could I buy to learn more? Is this the kind of info only available to ther bigger desks? Thanks for any help and your time.
