Short Selling Specific to India
In India, as suggested above, short/long position can be taken either in F&O or Spot market. The F&O segment short/long can be kept open for appx. 3 months by taking position on the far contract. In intra-day/Spot market, usually the position has to be squared at the end of day or the broker will square it during expiry (forcibly). However, having said that, it is a broker specific feature, as per National Stock Exchange (NSE) or Bombay Stock Exchange (BSE) any transaction has to be settled at the end of T+2 days (T being the trade day). Some brokers allow intra-day positions to be open for T+1 or T+2 days as long as the margin is provided. This is a broker specific discretion as the actual settlement is on T+2 (or in some cases as the exchange specifies). So, in general, to short a stock for a longer time, F&O segment should be used.
