Understanding Bulk Deals \ Large Deals of BSE and NSE

Dear Value Investors,

Sometime back I have learnt that we may be able to find large investment deals from Bulk Deals of NSE and BSE. I have seen many a times such deals are showing two transactions one buy and other sell, with nearly same quantity. What could the rationale behind executing such transactions? Request the experienced members of the group to throw some light on it.



Scalping is a trading style that specializes in profiting off small price changes. To make the trade meaningful, a large quantity has to be traded. It is done by high frequency trading.This large trade is recorded as bulk deal.
High-frequency trading, also known as HFT, is a method of trading that uses powerful computer programs to transact a large number of orders in fractions of a second.
The firms you see are HFT firms.


Thanks Akash, Very interesting

Some brokers take huge intra day positions n trade for small changes

As no of shares are huge , they make some good profits(maybe loss too) in these trades
