thats a good thread CC, not seen that one before
sqky - i found ED to have significantly more order flow than STIRs, but it also has its own unique quirks, like spoofers who load up one side or other of the spreads with 100k+ contracts.. you might think you've got yourself onto a good spread with some size to lean on but suddenly that size is gone and you're struggling for a scratch.
All part of the fun tho.
