And I'm a little confused about your question so I'm going to re-write it the way I understand it even if my grammar is crappy....hopefully it's the way you meant it:
Are you saying that trades are being made in EM that us retail investors are in the dark about?

For a proper discussion of that I'll refer you here:

But a concise answer to your question seems to be "No".
"Trades in Expert Market Securities that are not deemed “Restricted Securities” by FINRA1, are reported and distributed through normal market data distribution channels."

Theoretically we get to see all the trading activity in the "normal market data distribution channels" such as Ihub and OTCMarkets. FWIW Ihub and Y___ daily volume numbers have been identical since entry into the EM.

Also note that it is my understanding that insiders are prohibited from trading their restricted securities. This fact may be important to those who feel the Expert Market was entered willingly for reasons that I find unclear or just due to their inability to get their filing act together (that's my sense of it).
