Sorry guys, I have the attention span of a gnat. I meant to comment last night, but got distracted.
I think OTCX is OTCM. otcmarkets is public company.
MM OTCX apparently provides anon routing from several brokerages much like Knight Equities (NITE.)
Prolly explains why they both spaz all the time in L2.
Usually when I enter a new position, I will look at the ask and punch it in the face.
If the ask size is 20,000, I will hit it with 40,000 with the expectation that I will take out the top ask and leave bid support behind to protect my initial investment.
If I am immediately filled for the full 40,000 and the ask remains unchanged, I know I have bought into a blind ask.
Not sure if that makes sense to some.
Just IMO and FWIW.
