well its seems the symmetry is bothering you. after all we dont see such too often. pls dont go by that. it is just the market searching for its next move. just another setup. trade it just as you have traded an inside. take for example, between 11:40 and 11:55 the prices hovered in a narrow range of 772 and 773. just place 2 SL orders, buy above 773 or sell below 772, whichever comes first keeping the other as your stop.
i have uploaded a new file with much more details.

well the netvolume is the difference of +ive ticks and -ive ticks (and the sw its not MD). the sw scraps data from PIB, and data appended by PIB is not really tick data in its true sense (but good enough). pls check with another source for the exact figure.
cheers..
