Hi @Parthiban_Sub , Welcome to MadeForTrade!
Every transaction at the exchange is indeed considered a tick, but due to the extremely high frequency, it is not practical (or technically feasible) for all individual ticks to be broadcast in real-time. Instead, exchanges provide a snapshot tick — this includes a consolidated view of all transactions that occurred during that tick interval, which is commonly known as Last Traded Price (LTP).
This LTP is what you receive via the live market feed. It is updated with every snapshot tick and is used to plot charts and provide O/H/L/C (Open, High, Low, Close) data.
