How can i tracking orders

I’m trying to get the whale order When someone puts an order buy worth a thousand dollars and another person comes to sells $500 and then another person comes selling $500, so the order executes the purchase of $1,000, how can I monitor this process as one order and get the time of order to be executed like this example

Binance - [USDT Market]
#BTC - Unusual buying activity
259M USDT in 14 minutes (11%)
P: 21,520 :sparkle: (0.83%)
24H Vol: 2.61B USDT

It’s not possible to obtain data of individual public orders. A compromise can be done by listening to the order book diff stream and use the changes to understand large movement in the orderbook.
