%% HAPPENS in any market/that open[8.30 cst] + no fills sometimes..........................................................................................
There’s no trade through protection / NMS for otc markets. Sounds like you’re using IB - their otc quote data can be odd, sometimes showing worse BBO than the actual which can result in unexpectedly better fills if you try to cross the spread and hit a better quote in the middle they weren’t showing for some reason.
%% OK; i think they are not allowed to do that/ even if its as its a sub penny addition. BUT really it could be ' half a penny' LOL. in USa its illegal to cut a penny in half. Some grocers do the same ''marketing'' 3 @ $1.00, but charge $oo.34 for a single apple COUNT ON strange fills if its not super liquid.........................................................
