I would like to question your resolution of the market for August 20 (which was resolved to 'Yes').
In looking at your net worth graph it certainly looks as if you had a fair bit less at the end of the day than at the beginning.

Maybe I am missing something though.

@BorisBartlog The net worth decrease was due to one bet on this market, which happened the previous day. The graph was broken for a few hours.

@evan Ah, it must have just interpolated across the gap even though the drop was actually on Aug 19
