What Is Margin in Stock Market? Intraday Margin, MTF and Pledging Explained
“Get 5x margin!” Every broker app says something like this. But what is margin in the stock market, who lends it, what does it cost and how can it wipe out your account?
This guide explains margin in simple terms, covering intraday margin, the Margin Trading Facility (MTF), F&O margin and pledging, with rupee examples and the SEBI rules behind them.
What Is Margin in Stock Market?
Margin is the money you must keep with your broker to take a position. In some cases it is a deposit (F&O). In others, the broker funds the rest of the trade (intraday leverage and MTF).
Think of it as a down payment. You put in part of the value; the rest is either borrowed or simply blocked as security. Our margin FAQ gives the one-line version.
The 4 Types of Margin You Will Meet
| Type | Used for | Who funds the rest | Cost |
|---|---|---|---|
| Intraday margin | Buying/selling and squaring off the same day | Broker, for the day | Usually no interest |
| MTF (Margin Trading Facility) | Holding approved stocks beyond the day with borrowed money | Broker | Daily interest |
| F&O margin (SPAN + exposure) | Futures and option selling | No loan; it is a deposit | None, but capital is blocked |
| Pledge (collateral) margin | Using shares you own as margin | Your own shares, after a haircut | Pledge charges |
Intraday Margin: How Much Leverage Do You Really Get?
Under SEBI’s peak margin framework, brokers must collect an upfront margin of at least VaR + ELM on intraday equity trades. For most liquid stocks this works out to about 20% or more, so the maximum leverage is roughly 5x, and less for volatile stocks.
Example: with ₹20,000 in your account, you could take an intraday position worth up to about ₹1,00,000 in a stock with a 20% margin requirement.
If that stock falls 3%, you lose ₹3,000. That is 15% of your capital gone in one move. Leverage magnifies losses exactly as much as gains. Brokers also auto square-off open intraday positions near the close, often with a charge.
MTF: Margin Trading Facility
MTF lets you buy approved stocks by paying part of the value and holding them for days or weeks. The broker funds the balance and charges interest every day. The shares you buy are pledged to the broker as security.
Example: You buy shares worth ₹2,00,000 under MTF, paying ₹1,00,000 yourself. If the broker charges 15% a year on the funded ₹1,00,000, interest is about ₹41 a day, or roughly ₹1,250 a month. Your trade must earn more than that just to break even. Interest rates vary by broker, so check the exact rate before you use MTF.
If the stock falls and your margin drops below the required level, you get a margin call. Add funds quickly, or the broker can sell your shares.
F&O Margin: SPAN and Exposure
To trade futures or sell options, the exchange requires SPAN margin (worst-case one-day loss) plus exposure margin (an extra buffer). Together this is often a sizeable share of the contract value. Option buyers pay only the premium, not SPAN margin.
Hedged positions, like a spread where you buy one option and sell another, often need much less margin than a naked sale.
Pledging Shares for Margin
You can pledge shares in your demat account to get margin for F&O or intraday. The exchange applies a haircut, meaning only part of the share value counts. Brokers may also require part of the F&O margin in cash, not only pledged shares. Pledging is how traders run strategies like the covered call without blocking extra cash.
Margin Risks Beginners Ignore
- Small moves, big losses. At 5x leverage, a 4% fall costs 20% of your capital.
- Interest drag on MTF. Holding a losing MTF position costs you twice: loss plus interest.
- Forced selling. Margin calls can trigger sales at the worst prices.
- Overtrading. Easy leverage tempts you into bigger and more trades. Read our FAQ on overtrading.
How to Use Margin Safely
- Size positions on risk, not on available margin. Use the 1% rule for position sizing.
- Always place a stop-loss before using leverage.
- Use MTF only for short holds with a clear exit plan.
- Keep a cash buffer to avoid margin calls.
- Read your broker’s margin and interest policy; SEBI’s 2026 stock broker rule changes affect how brokers handle client funds.
