Highest Currency Volume in 10 Years. Who is it?

I am new to the forum so thank you for answering this Volume Question.

If you look at the GBPUSD and EURUSD charts attached to this post you will see that the Volume spike is amazing. Anyone who can give an idea as to what this means.

Thanks

i dunno but you can't track real volume due to forex being decentralized.
maybe volume at one broker but I bet that indicator is based upon something else

Metatrader volume is simply tick volume. I think a lot of that change is due to a change to 5 digit quotes, which have a higher tick rate than 4 digit quotes.
