The OTC almost always mimics these two exchanges a few hours after the euro exchanges close on MRPHF, so about 5am CST you can get a very good picture of how MRPHF will trade on the OTC that day. Its like having a 4 hour head-start on who won the Superbowl.
As you can see it ran from $1.00 to $1.27 almost exactly what it did on the OTC but 12hrs earlier.
