just thinking out loud here, not reccomending or encouraging this at this point, but if anyone was interested in sharing some thoughts, if we as a trading community really wanted to make a statement and influence trading rules what could we do? if we wanted to flex some muscle over i.e. over the new liquidity rules. how much volume do we account for on the NYSE, speaking of prop traders, retail, independents, etc.. basically all active traders off floor? i.e bright says they account for about 5% of daily volume, as do many other firms account for a few %.... the timing may be trick too as when to do it, or how long to have the most impact....maybe for a day or a week during a slow time, idk, what do you think?
