Ann: Market Update - Progress Report, page-180

First noticed reloader at 11:42, decided to take sceeenshots after the 12:15 trade...


...then a few seconds after each trade thereafter. Low amount of trades makes it easy to follow, market depth not changing much outside of trade prices, so should be self explanatory, no prizes for guessing who's the yellow trades were...






Reloader changes reload level to $14.23.



Last one is most interesting - auto bid of 836 shares immediately after mine at a cent higher which was matched by the reloader, who then reloaded immediately back at the $14.23 level. Stopped taking screenshots after this.
