I'm not a high frequency trader. When I want to sell (all highly liquid shares), I've made that decision on other factors than a 0.1% variation of the listed stock price. What I care about is that it sells. It's hold-over from the dotcom days when I saw colleagues sell options with a limit order just above the current listed price that never got fulfilled in an a constant down market.
