Вопрос по объемам на FX - в догонку к вчерашнему обсуждению

Нашел прогноз Deutsche Bank по евро:

«The euro is up 3% since the now infamous non-taper FOMC meeting of mid-September. However, all of the move can be explained by 3 days: the non-taper day (Sep 18), the end of the government shutdown (Oct 17) and poor payrolls Tuesday. Outside of those days, there has been no strength in the euro. This contrasts with the move higher between mid-July to late August, where the euro generally appreciated outside of big „up days. This goes into a deeper issue that the euro rally since July has been off the back of declining FX volumes (see chart below). There is no depth to this move, and increasingly euro strength is coming on event days. So unless one is confident of the outcome of key event days, and remember a series like payrolls is very very noisy (see chart), then it makes little sense to go long euros.“

 

Так вот вопрос — что это за объемы на картинке, которую приводит Deutsche Bank? Где они их смотрят?
