Basel Financial confirmed that they are ECN.
they have fixed spreads for majors, the rest is variable.
They've chosen to quote those fixed spreads because, as they say: "most of the time we get institutional spreads that are less than 1 pip", so they mark up the spread and deliver a fixed number to a client. For the same reason, I suppose, they don't need to charge commission.

The approach is different form a standard ECN model, as you can see. I'll keep them on my list, but won't list them among ECNs for now. I'd like to do some more checks.

P.S. Their scalping policy also doesn't fit the ECN model, they would tolerate it only after increasing spreads, lowering leverage or/and adding a commission for those who came to scalp.
