Just as note, a T trade on OTC markets are not necessarily (probably not)a trade occurring after the market. However they are buys or sells as indicated.An explanation of a T trade is :
"To avoid creating “an unbalanced market”, market makers often do not report certain trades during the day to the public and then use a T Trade not to “scare” investors into thinking a market for that stock is going in one direction or the other at the spurring of one large investor.
If a market maker wants to accumulate a large amount of a stock in one trading day, that market maker may actually not report any of the trades that occurred until the trading day has ended so as not to alert the market to the collection. This practice is completely legal under the FINRA rules of the OTC Markets so long as the trade is reported at the end of the day.
To execute a Market on Close” order, a market maker may have an order to purchase the stock at a certain price at the end of the trading day. This is the most unlikely scenario because it needs to be assured that someone selling the stock and someone buying that stock are agreeing upon a price. Simply put, this is more likely with insider buying and selling."
The T Trade reported at the end of the day can be from one market maker or many involved market makers. It can be a single purchase price but is usually an average of all of the previously unreported purchases from that business day.
