That trade was executed about 30 min before the EOD bell. It was a late print and was not recognized until after the bell. It occasionally happens in the grey market, completely normal.
As for AH trading in the pinks, as many other members have stated, they do not trade in AH or PM trading. If you don't believe anyone about it, simply try to place an extended hours trade yourself. You will get as far as the submitting agreement and then it will be rejected once you try to submit it.
A lot of people don't understand the blindness in pink sheet stocks (not directly speaking to you, just in general). MM's don't have to show anything they don't want seen. Level 2's can look different from my platform to yours, trades can be privately selected (to buy or sell) quantity of shares can be hidden, and so much more. Trading pinks is like playing baseball with your eyes closed and hope you hit a home run. 99.99% of heavy movement in pink sheet stocks is pure manipulation. Hell I've manipulated penny stocks before, you just need to know what you're doing and be extremely careful.
Anyway, feel free to ask any other questions you may have I will be glad to answer them.
