during that trading day, VNDM, or whomever is sell

during that trading day, VNDM, or whomever is selling the block, sells into the market and that is the volume for the day. The t trade is just all of his trades during the day bunched up and reported at an average price in one block after the close because it is easier for bookkeeping purposes. Over the course of the trading day, VNDM (just using him as an example) may execute 10, 20 or even 30 trades in various sizes and even at various prices. At the end of the trading day he will take his trading blotter (at least thats what we did 20 years ago) and add up all the shares and an average price. Lets say over the course of the day he dumped 20million shares at at average cost of say .00052 (they execute some inbetween bid and ask). He will then post a t trade of the 20million shares at say .0005 to the seller and make that small amount for himself. .00002 X 20million so he made himself about $400 just sitting there executing some trades and torturing us. Thats why you get the volume bump after 4pm but is just a block trade and not a fresh sell, the shares were already absorbed during the trading day most likely by us and other buyers. This is how it has been done for decades so people can sell and nobody will know who they are. These guys like VNDM will rarely give up who the seller is because they want the business. NITE is also notorious for that. Hope this was helpful
