No; it isn’t.
If you think about how the forex market (interbank market) actually works, it’s actually very clear why it isn’t possible.
(And it isn’t just “not possible” for you and for me and for your broker and for my broker: there isn’t one single market participant who can see the volume of the forex market.)
The essential point is that it isn’t a centralised market. There’s no one place where volume is recorded or collated. It’s going on all over the world, all the time, in private, between hundreds of financial institutions whose information isn’t (and can’t be) collected together and studied.
So how could it possibly be known to anyone?
Forex futures are completely different: they’re traded through a single, centralised exchange, so the volumes transacted are recorded (and made available). But spot forex, no - not at all.
Note that any “trades” you do with a counterparty broker of the type that 99% of this forum’s members are using aren’t part of the interbank market anyway. They’re effectively just “side-bets” against a “broker” on the price movements. No currencies really change hands between yourself and your “broker” when you “trade” (but your broker might offset their own net liabilities in an underlying market, and if they do, even that isn’t collectively recorded or collated or available anyway.)
That’s really not so, at all.
It’s “hidden” from you for the same reason that it’s “hidden” from everyone else: there just isn’t a way of measuring it.
(And by the way some people - a very small minority - are winners, not losers; you surely can’t imagine that all the people trading forex full-time, for a living, some of them for decades, are losers???)
