There seems to be an influx of option markets makers offering subscriptions promising you to give you on info on options that might move. I am sort of puzzled on this. First of all I can't figure out how they can provide quotes to customers and be on Twitter or on subscription services during trading hours to share trades at the same time? I used to sit at an options market maker desk and trust me we sometimes had to sit and answer quote requests when we really badly needed to take a break. You have to provide a quote within a certain time frame. If they are so successful in trading big volumes and market making why are they offering such subscription services? Your thoughts?
