Outside of normal market hours, i do believe most of the conversions are being routed through overseas exchanges to mask the dilution... But please explain how you know it wasn't a conversion...
Omvs is steadily diluting, in need of funds and masks this with the gagged TA..
The T-trades are blocks of shares given to the mm to sell during the day. They could come from a variety of places. Insiders, IR given shares for services, promoters given free trading shares, a beneficiary holder slowing unloading, and debt holders.
