Closing an open trading position by executing an opposite transaction - selling if long or buying if short - to realise the profit or loss.
Squaring off means closing an open trading Position by executing the reverse trade. A long position (bought shares) is squared off by selling the same quantity. A Short Position (sold shares or futures) is squared off by buying back. The difference between entry and exit price, multiplied by quantity, is the realised profit or loss.
In Indian markets, squaring off is particularly important for intraday traders. All intraday positions on NSE/BSE must be squared off before 3:15-3:20 PM (cutoff times vary by broker). Positions not squared off by the trader are automatically closed by the broker's Risk Management System (RMS) at the prevailing market price - a forced square-off that may result in unfavourable execution, especially in fast-moving markets.
For futures positions, squaring off before the monthly or weekly expiry avoids physical delivery obligations. SEBI's physical settlement mandate for stock futures means that any stock futures position held to expiry must give or take delivery of the underlying shares. This requires full margin (not just futures margin), and pre-expiry square-off is the dominant practice across most traders.
The timing of square-off can significantly impact outcomes. Indian traders observe the "3:15 effect" - a rush of auto-square-off orders from multiple brokers hitting the market simultaneously near the end of the day, causing sudden price movements. Many active traders square off positions well before this window or factor the potential impact into the trading plan.
Tax implications of squaring off matter too. Intraday square-offs (opening and closing within the same session) are classified as speculative income under Indian tax law and taxed at slab rate. Delivery-based trades (held overnight or longer) qualify for capital gains treatment - STCG at 20% for holdings under 12 months and LTCG at 12.5% for longer holdings.
