In recent [sharesansar article](https://www.sharesansar.com/newsdetail/look-into-the-nepse-market-participation-measurement-through-value-per-transaction-2022-05-20), it shows different VPT values at different times. But what I don’t understand is that how does VPT differ?
Say there are total of 1000 shares traded, and it is traded 10 times at average of 100 units. In bull market, even if big player plans to purchase 1000 units, and they accumulate 100 units each times for 10 times. So there are 10 transactions for 1000 shares. Say big players are exiting and plan to sell 1000 shares which retail investors are purchasing, and retail investors purchase 100 units each time for 10 transactions, VPT remains constant. Or is it just looking at if there are big transactions happening which signifies bigger players are playing in the market.
I know I am missing something but I am not sure what I am.
