Statistics are presented with graphs and matrices. The three graphs, first graph at top is all percentiles and quartiles and MAX and MIN, next is reduced to P90 and P10, the bottom graph is scaled to the upper and lower quartile.
Third graph from the top is the one that is most useful, noting the normal range for this month end with the mean and median in the middle of the field. In this post there are matrices that show different values for the calculated period and most importantly win rate, profit factor and avg. trade %, but also index points, sum %.
I would say this Turn of the Month have in history been quite bad and you have to be more careful trading this TOM. BUY and SELL according to statistics is always done at closing price.
