>> Touch Line Data consists of the fields at any given time of the day during or post-market.

The touchline data is sent to you whenever you add a symbol.

The touchline is also pushed to you automatically at the pre-open start of each market - MCX - 08:45 & NSE 09:00. This update comes with updated previous Close information which helps you get the correct change and change % as the markets start.
