# Delivery surge — NSE scan

> Over 65% of a heavy day's volume taken to demat. Buyers who intend to hold, not day traders — and a figure most screeners do not expose as a field at all.

NSE publishes, for every stock every day, how much of the traded volume was actually delivered to a demat account rather than squared off intraday. High delivery on high volume means the buying was done by people taking the stock home — the single most useful field in the dataset, and one most screeners show as a column rather than let you scan and backtest on.
