If cash trading means paying the full amount upfront, why does the exchange ask for only 20%?
Because those are two different rules. The exchange sets a floor. Your broker sets policy above it. Most explanations of what is cash trading skip that gap, what the trade costs, and the one way a cash trade still fails.
What is Cash Trading?
Cash trading is buying and selling shares in the capital market segment of NSE and BSE with your own funds, taking delivery.
The shares move into your demat account, the electronic account holding securities in your name. Broker platforms label the order type CNC, short for Cash and Carry, or simply Delivery.
Two things define it. You are not borrowing, so no interest accrues. You own the share itself, not a contract on it, so no expiry pushes you out.
The cash trading meaning most people carry is “pay 100% upfront”. That is close. The real rule is more precise, and the gap costs money.
How Does Cash Trading in the Stock Market Work?
You place a buy order, and before it executes your broker collects margin.
NSE requires trading members to collect a minimum 20% upfront margin in lieu of Value at Risk and Extreme Loss Margin, the two standard exchange risk margins. On a ₹1,00,000 order that floor is ₹20,000. Anything above it is broker policy, not an exchange rule.
Settlement runs on a T+1 cycle. NSE Clearing sets obligations on the trade day and settles the next working day, holidays excluded.
Then the charges land. The brokerage charges at Indiabulls Securities are 2.5% or ₹11 per executed order, whichever is lower, across NSE (CM, FO, CD), BSE (CM, FO) and MCX. Securities Transaction Tax (STT) and Goods and Services Tax (GST) sit on top.
Charge | Buy leg | Sell leg | Total |
Brokerage | ₹11.00 | ₹11.00 | ₹22.00 |
STT, 0.1% per leg | ₹100.00 | ₹100.00 | ₹200.00 |
NSE transaction, 0.00307% | ₹3.07 | ₹3.07 | ₹6.14 |
Stamp duty, 0.015% buy side | ₹15.00 | Nil | ₹15.00 |
SEBI, ₹10 per crore | ₹0.10 | ₹0.10 | ₹0.20 |
GST, 18% | ₹2.55 | ₹2.55 | ₹5.10 |
Total on ₹1,00,000 bought and sold | ₹248.44 |
STT is ₹200 of that ₹248.44. Brokerage is ₹22. The largest cost in a cash trade is not your broker. A depository debit charge also applies on the sell leg, per scrip rather than per share.

Key Features of Cash Trading
Ownership transfers to you. Once the shares sit in your demat account, dividends and any bonus or split entitlement come to you directly, and you can vote.
There is no forced exit. No interest accrues, no margin call arrives, and your broker cannot square off the position over a funding level.
Your loss is bounded by what you put in. A stock can fall hard, a real loss, but it cannot generate a bill larger than the capital deployed.
Settlement is not always next day. NSE runs an optional T+0 same-day cycle alongside T+1, where trades execute till 1:30 PM and payout releases that day.
Types of Cash Trading
Ask what is cash trading in stock market practice, and there is no single answer. Three trade types run inside the same segment.
Delivery means you buy, pay, take the shares into your demat account and hold as long as you want. Most people mean this by cash trading.
Intraday means you buy and sell the same scrip the same day, so nothing is delivered. STT drops to 0.025% on the sell leg only, against 0.1% on both legs for delivery.
Buy Today Sell Tomorrow, or BTST, means selling the next day before the buy leg settles. Most equity trading platforms restrict it, because the shares have not reached your account.
Cash Trading vs Margin Trading vs Futures & Options
Feature | Cash trading | Margin Trading Facility | Futures and Options |
Capital needed | Full trade value | As low as 25%, approved stocks only | Span and exposure margin |
Funding cost | None | Flat 14% a year on the borrowed amount, till closed | None |
Holding period | Unlimited | Weeks or months, if margin is maintained | Till expiry |
Forced exit | No | Yes, on margin shortfall | Yes, on expiry or shortfall |
Loss exposure | Capital deployed | Amplified in proportion to gains | Can exceed capital deployed |
Every rupee of extra buying power gained through margin trading brings an equal rise in loss exposure. Futures and Options carry a high risk of loss, including losses beyond the capital deployed. Cash trading surrenders leverage and removes both.
Advantages of Cash Trading
- Your maximum loss is the capital you deployed, and nothing beyond it.
- No interest accrues, so holding for longer costs nothing extra.
- No margin call can force you out at the wrong moment.
- Dividends, bonus issues and voting rights reach you directly.
- No expiry date applies, so a view can take years to play out.
A falling price stays a decision instead of an emergency. You choose whether to hold or sell. Nobody sends a notice. For a new investor that matters more than leverage, because many beginner losses come from being forced out rather than from being wrong.
Risks and Limitations of Cash Trading
Bounded loss is not the same as no cost and no obligation.
Capital gets blocked. The full trade value sits in one position until settlement completes after a sale. You also give up leverage, so ₹25,000 buys ₹25,000 of stock and no more.
A delivery obligation can also fail. Sell shares without delivering them on settlement day, and NSE Clearing raises a valuation debit, then runs a buying-in auction.
If the shortage cannot be bought in, the trade is closed out at the higher of two prices. One is the highest NSE price from the trade day to the auction day. The other is 20% above the official closing price that day.
Tax adds to it. Gains on shares sold within 12 months are taxed at 20% under Section 111A. Beyond 12 months, gains above ₹1,25,000 a year are taxed at 12.5% under Section 112A, subject to prevailing rules.
Who Should Choose Cash Trading?
Cash trading suits you if you are buying shares to own them, not to trade a move. That covers first-time investors, anyone building a portfolio across years, and anyone who applies for shares in an ipo and holds them after listing.
It is a poor fit in three situations. If you need the same capital working in two positions at once, full payment will frustrate you. If you would rather not pick individual stocks, mutual funds hand that job to a fund manager. And if you hold for hours, the delivery cost structure is the wrong one to pay.
If cash trading aligns with your investment approach, you can start equity trading online and explore equity-market opportunities through Indiabulls Securities.
Tips for Successful Cash Trading
- Price the trade on a brokerage calculator before you place it, not after.
- Ask your broker whether it blocks the exchange floor or the full trade value.
- Never sell shares not yet credited to your demat account.
- Track the 12-month mark on every holding, because the tax rate changes there.
- Read the contract note, not the app’s profit figure, for what you paid.
Cost as a share of position size is worth watching. On a ₹1,00,000 trade the charges above come to roughly 0.25%. Run the same ₹11 brokerage over a ₹5,000 trade and that share roughly triples.
Conclusion
Cash trading is the plainest structure in the equity market. You pay, and the shares are yours until you sell. It is not free, and it does not remove your obligation to deliver what you sold.
Before your next order, do two things. Ask your broker what share of trade value it blocks at order placement, since the exchange floor is 20% and the rest is policy. Then price the round trip, so your contract note holds no surprise.
