My gym has stationary recumbent bikes -- I wonder if rigging up a keyboard to one of those would be better? If you don't need to put your upper body weight on handlebars, maybe it'll be easier to have a more traditional mouse/keyboard setup.

If you’re an options market maker and you are 10ms slower, you legitimately will be obsolete in the market. You will be arbitraged against when stocks move and you are slow to update quotes. This happens all the time, and it makes it so that you have to quote so wide that you aren’t competitive. Milliseconds are the difference from being competitive and going broke in the industry.
