Quote from wilburbear:
Yeah, but on a market of, say, 2.00 bid, 3.00 offer, if you cleverly go 3.01 bid, a market-maker algorithm will go 3.02 bid. This can go on and on. Then if you cancel, all the market-maker bids will go back down to 3.00. That is the current state in equities.
Penny pricing in options will be a disaster, unless you are buying offers or hitting bids. In those cases you are losing money as soon as you touch the market. You instantly give up theoretical value edge.
Algorithms will harass you out of bids and offers that are good values.
Comment to the SEC.
Actually, the situation will be a little worse than what you describe. The order book queuing algorithms work because they are creating an instantaneous option with their position in the order queue. What instantaneous option am I referring to? Why, its your order of course! This cannot happen in the options market, because there is a known theoretical fair value for the option. If the algorithm simply placed orders ahead of you in the queue, it would eventually exceed fair value and get executed with a negative expectancy. The impact of penny quoting in the option markets will be a lack of liquidity. When every 2-cent change in the underlyer results in a 1-cent change in the derivative (or worse), market-makers will simply widen their spread and deepen their quote to avoid quoting every 1/2 second.
