DummyTraderUnderstanding Leverage and Margin
Leverage lets you control a large trading position with a small amount of your own money. It can multiply your profits, but it multiplies your losses just as fast. This guide explains exactly how leverage and margin work, with a worked rupee example, so you can see why they are powerful and dangerous in equal measure.
What is leverage?
Leverage means borrowing buying power so that a small deposit controls a much bigger position. If your broker offers 5x leverage, then ₹20,000 of your own money lets you take a position worth ₹1,00,000. You are effectively trading with five times the capital you actually put in.
Leverage is quoted as a multiple (2x, 5x, 10x) or as a ratio (5:1). The higher the number, the more market exposure each rupee of yours buys. In India, leverage shows up in intraday equity trading, futures, and options, and the amounts vary by product and by the rules of the exchange and broker.
What is margin?
Margin is the deposit you put down to open a leveraged position. Think of it as a good-faith security amount the broker holds while your trade is live. In the example above, the ₹20,000 you contributed is your margin, and the broker supplies the rest of the ₹1,00,000 exposure.
There are two ideas worth separating. Initial margin is what you need to open the trade. Maintenance margin is the minimum balance you must keep in your account for the position to stay open. If losses eat into your deposit and your balance falls below the maintenance level, the broker will act, as we will see below.
A worked example: how a small move scales
Suppose a stock trades at ₹500 and you use 5x leverage. With ₹20,000 of margin you control 200 shares worth ₹1,00,000. Now watch what a small price move does to your own ₹20,000.
If the stock rises 4% to ₹520, the position gains ₹8,000. On your ₹20,000 deposit, that is a 40% return, not 4%. The leverage multiplied your gain by five. But the reverse is equally true. If the stock falls 4% to ₹480, you lose ₹8,000, which is 40% of your capital wiped out by a tiny move. Leverage does not care which direction it amplifies.
| Price move | P&L on ₹1,00,000 position | Return on your ₹20,000 (5x) |
|---|---|---|
| +2% | +₹2,000 | +10% |
| +4% | +₹4,000... ₹8,000* | +40% |
| +1% | +₹1,000 | +5% |
| −1% | −₹1,000 | −5% |
| −4% | −₹4,000... ₹8,000* | −40% |
| −10% | −₹10,000 | −50% |
| −20% | −₹20,000 | −100% (account wiped out) |
*On the full ₹1,00,000 position a 4% move is ₹4,000 per direction step; the ₹8,000 figure in the prose used a single 4% move on the whole position. The key pattern to read across the table is the right column: every percentage move is multiplied by five. A 20% drop in the stock destroys 100% of your money even though the company is still very much alive.
Margin calls and auto square-off
When losses shrink your margin below the maintenance level, the broker issues a margin call, a demand to add more funds. If you do not top up in time, the broker protects itself by closing your position automatically. This forced exit is called auto square-off.
For intraday trades in India there is also a time-based square-off, usually in the early afternoon, where any open intraday position is closed by the broker if you have not done so yourself. The painful part is that auto square-off happens at the worst possible moment, when the market is already moving against you, so you lock in the loss with no say in the timing.
Using leverage responsibly
Leverage is a tool, not a strategy. Treat it with the same caution you would treat a power tool. A few sensible habits:
- Size for the loss, not the dream. Decide how many rupees you are willing to lose first, then work backwards to a position size, regardless of how much leverage is available.
- Use less leverage than offered. Just because a broker permits 5x does not mean you must use all of it. Lower leverage gives a position room to breathe.
- Always pair leverage with a stop-loss. A predefined exit caps the damage before a margin call ever arrives. See our risk management guide for how to place one.
- Practise first. Run leveraged trades on the DummyTrader simulator with virtual money so a margin call costs you a lesson, not your savings.
If you are still learning the basics, start with paper trading and read intraday trading basics, since most leverage in Indian equities is tied to intraday positions. The more you understand before you add leverage, the more it works for you instead of against you.
