Square Off in Indian Markets: Cutoff Times, Penalties and Tax

What Square Off Actually Means

In the Indian market, square off is the act of closing an open position by executing the exact opposite trade for the same quantity in the same scrip or contract. If you bought 100 shares of Reliance, you square off by selling 100 shares of Reliance. If you sold (shorted) one lot of Nifty futures, you square off by buying back one lot of the same Nifty futures contract. The two trades cancel each other out and your net holding returns to zero, which is why traders also call it closing or exiting a position.

Square off is a position level idea, not an order type. You do not press a button labelled square off on most platforms. Instead you place a normal opposite order and the system nets it against your existing position. Your booked profit or loss is simply the difference between your entry price and your exit price, multiplied by quantity, after costs. A square off can be full, where you close the entire position, or partial, where you close only some of the quantity and let the rest run.

The reason square off dominates intraday trading is that intraday product types such as MIS (Margin Intraday Square off) and CO (Cover Order) are not designed to carry overnight. The exchange and broker expect them to be flat by the end of the session. If you do not close them yourself, the broker closes them for you, and that is where cutoff times and penalties become very real money.

The Auto Square Off Cutoff Times You Must Know

The single most important fact this page must correct is timing. The NSE and BSE equity markets close at 3:30 PM IST, but brokers do not wait until 3:30 PM to close your intraday positions. They start a few minutes earlier so that they can finish before the bell. The exact minute is set by each broker, not by SEBI, so it varies slightly, but the windows below are typical and well documented for large Indian brokers.

These windows are broker policy, so always confirm the exact time inside your own broker. For example, Zerodha publishes that it begins auto square off of open MIS equity positions at 3:20 PM and of open equity derivatives positions at 3:25 PM. The practical rule for almost every Indian retail trader is simple. Treat 3:15 PM as your personal deadline for cash intraday and 3:20 PM for index and stock F&O. Closing yourself before the broker process starts means you, not an automated queue, choose the exit price.

The Real Broker Penalty For Auto Square Off

Letting the broker square off for you is not free. Most discount brokers charge a specific penalty per auto square off order, on top of normal brokerage and statutory charges. This is the second fact the older version of this page left vague, and it costs traders real money every day.

Note that this penalty is charged per order, not per day. If the broker has to close three separate open intraday positions for you, you can be billed the penalty three times. These figures are illustrative and change over time, so confirm the current number on your broker tariff sheet before you trade. The point is that the cost is fixed and avoidable. A single self placed exit before the cutoff saves the entire penalty.

Worked Example One: Nifty Futures Intraday Square Off

Assume it is a normal trading day and you go long one lot of Nifty futures. The Nifty lot size is 65. You buy at 23,400 in the morning expecting a bounce. By 3:00 PM Nifty trades at 23,480, so you decide to square off manually well before the broker cutoff. All numbers here are illustrative and not a forecast.

• Entry: buy 1 lot Nifty futures at 23,400, quantity 75.
• Exit (square off): sell 1 lot at 23,480, quantity 75.
• Gross move: 23,480 minus 23,400 equals 80 points.
• Gross profit: 80 points times 75 equals Rs 6,000.

Now subtract realistic costs. On a discount broker, intraday futures brokerage is often a flat Rs 20 per executed order, so about Rs 40 for entry plus exit. STT on futures applies to the sell side only at 0.02 percent of the sell turnover. Sell turnover is 23,480 times 75, which is Rs 17,61,000, so STT is roughly Rs 352. Add exchange transaction charges, SEBI fee, stamp duty and 18 percent GST on brokerage and transaction charges, and total costs land roughly in the Rs 450 to Rs 550 range. Your net profit is therefore close to Rs 5,450 to Rs 5,550. If instead you had let the broker auto square off at 3:25 PM, you would also pay the roughly Rs 59 penalty plus accept whatever fill the batch gave you, which on a moving market could easily be several points worse, quietly eating a few hundred rupees more.

Worked Example Two: Equity Intraday And A Missed Cutoff

Suppose you buy 200 shares of HDFC Bank intraday under MIS at Rs 1,650, planning to scalp a move. The stock drifts to Rs 1,656 by mid afternoon, then you get distracted and forget to exit. This example shows what a missed square off actually costs. Numbers are illustrative.

The difference between the two rows is stark. By missing the cutoff you turned a roughly Rs 1,100 net winner into a roughly Rs 540 net winner, a swing of more than Rs 500 on a single trade, mostly from the worse auto square off fill and the fixed penalty. Over a year of active intraday trading, repeatedly letting the broker close your positions can cost tens of thousands of rupees in penalties and slippage alone. This is precisely why disciplined intraday traders never rely on the auto square off.

Square Off In Futures And Options

In derivatives, squaring off means taking the opposite position in the same contract before it expires. If you bought one lot of a Bank Nifty monthly call, you square off by selling one lot of that exact same strike and expiry. Bank Nifty lot size is 30, Nifty is 75, FinNifty is 25 and Sensex is 10, so always compute profit and loss using the correct lot size for the underlying.

Here is a quick options example. You buy one lot of a Nifty 23,500 weekly call at a premium of Rs 90. The lot size is 65, so your cost is 90 times 75 equals Rs 6,750 plus charges. Nifty rallies and the premium rises to Rs 140. You square off by selling that same call at Rs 140. Gross profit is (140 minus 90) times 75, which is 50 times 75 equals Rs 3,750, before brokerage, STT and other charges. Note that on options, STT is charged at 0.1 percent of premium on the sell side, and for exercised in the money options STT is charged on intrinsic value, which is one reason traders prefer to square off rather than let a profitable option expire and get exercised.

If you do not square off an in the money option by expiry, it is settled rather than closed by you, and you lose control over both the price and the exact charges. For index options this is cash settled at the closing settlement price, while many stock options move toward physical delivery, which can trigger large margin and delivery obligations. Squaring off before expiry keeps you in control of your exit and your costs.

Weekly And Monthly Expiry Mechanics

Indian index derivatives have weekly and monthly expiries, and the expiry day matters for square off because an unclosed position does not simply vanish, it gets settled. Monthly stock and index futures and options expire on the last week of the month, while index weeklies expire on the specific weekday set by the exchange for that index. Exchanges have revised expiry days from time to time, so always confirm the current expiry calendar on the NSE or BSE website before you trade an expiry.

On expiry day, if you are holding an option you intend to close, square it off during the session like any other day. If you let it run to expiry, index options are cash settled at the final settlement value and your account is debited or credited accordingly, with no manual square off needed but also no control over the price. The key discipline is the same as intraday: decide before the close whether you are squaring off or letting it settle, and never get surprised by an expiry settlement you did not plan for.

• Weekly index options expire on a fixed weekday set by the exchange; confirm the current day on NSE or BSE.
• Monthly contracts expire in the last week of the month and roll into the next series.
• Unclosed in the money index options are cash settled at the settlement price, not at your chosen price.
• Stock F&O can head to physical delivery if not squared off, creating large margin needs.

Tax Treatment When You Square Off

How your squared off profit is taxed depends entirely on the product, and this is widely misunderstood. Intraday equity trading, where you buy and sell the same stock the same day without delivery, is treated as speculative business income. It is added to your total income and taxed at your applicable income tax slab rate, not at the capital gains rates.

Futures and options profit, whether on indices or stocks, is treated as non speculative business income. It too is taxed at your slab rate and can be set off against most other business income. Crucially, neither intraday equity nor F&O is taxed at the capital gains rates. The 20 percent short term capital gains rate and the 12.5 percent long term capital gains rate above the Rs 1.25 lakh exemption apply only to delivery based equity investments where shares hit your demat account, not to positions you square off the same day or to derivatives.

Because intraday and F&O are business income, you can claim related expenses such as brokerage, STT in some cases, internet and advisory costs against the profit, and a tax audit may apply above certain turnover thresholds. Keep a clean record of every squared off trade. A trading journal that logs entry, exit, quantity and charges makes this filing far easier and is good risk discipline regardless of tax.

Square Off Versus Delivery Trading

Square off and delivery are two different intentions. When you square off, you never intend to own the shares overnight, so nothing reaches your demat account. When you take delivery, you buy under the CNC or delivery product, the shares settle into your demat under the T plus 1 cycle, and you can hold them for days, months or years. The same buy order can become either, depending on the product type you choose and whether you close it the same day.

A subtle trap is the product type at order time. If you buy under MIS expecting to square off but the price runs against you, you must still close before the cutoff or the broker does it for you at a poor price plus penalty. Some platforms let you convert an MIS position to CNC delivery before the cutoff if you have the full cash, which is one legitimate way to avoid an unwanted square off, but only if you genuinely want to own the stock and can fund it.

Common Square Off Mistakes And How To Avoid Them

The costliest square off mistakes are almost always about discipline and timing, not market direction. Knowing the exact cutoff and the penalty turns a vague worry into a hard rule you can follow.

• Relying on the broker to close your trade. You pay the penalty, about Rs 59 on Zerodha, and accept a worse batch fill. Always exit yourself before the cutoff.
• Not knowing your broker cutoff. Treat 3:15 PM as the deadline for cash intraday and 3:20 PM for F&O, then confirm the exact minute in your broker.
• Ignoring charges. Brokerage, STT, exchange fees, stamp duty and GST can turn a small gross gain into a net loss on a thin scalp.
• Confusing square off cost with short delivery cost. The auction penalty for genuine short delivery is far larger than the simple auto square off fee.
• Letting a profitable option run to expiry. You lose control of price and may pay STT on intrinsic value or face physical delivery on stock options.
