What exactly is Margin in the stock market?

Margin is a good-faith deposit required by your broker to allow you to take leveraged positions (intraday) or trade highly volatile Futures & Options contracts. It ensures you have enough collateral to cover potential losses.

What is the maximum intraday margin allowed by SEBI in 2026?

Under SEBI's Peak Margin regulations, the maximum intraday leverage allowed for equity cash trading is 5x (which mathematically requires a 20% upfront margin). The days of brokers offering reckless 20x or 40x leverage are permanently over in India.

What is a 'Margin Call'?

A Margin Call is a terrifying alert from your broker stating that your account balance has fallen below the required maintenance margin due to extreme trading losses. You must immediately deposit fresh cash within hours, or the broker will forcefully sell your shares at whatever disastrous price the market is offering.

Why does Option Selling (Writing) require so much margin compared to Option Buying?

Option buyers only risk the premium they pay (maximum loss is defined). Option sellers (writers) carry UNLIMITED theoretical risk. If you sell a Call option and the stock rallies 500%, you owe massive amounts of money. Therefore, exchanges block massive Span margins (often ₹1L+) to ensure the seller can honor their catastrophic losses.

What happens if I forget to close my leveraged intraday (MIS) trade by 3:15 PM?

Your broker's automated risk-management system will trigger a forced 'Auto Square-off'. They will forcibly sell your entire leveraged position at exactly 3:15 PM (or 3:20 PM depending on the broker) at market price. Most brokers also charge a hefty ₹50 penalty fee for this forced liquidation.

Is margin calculated differently for Futures?

Yes. Futures contracts don't use 5x fixed leverage. They use a dynamic Span Risk model. Highly volatile stocks require much larger Span margins (e.g., 30-40% of contract value), while stable index futures like Nifty only require about 10-12% combined margin.

Can I use my existing stock holdings as margin?

Yes. Most major brokers offer a 'Margin Pledge' facility. You can pledge your delivery stocks or mutual funds to the clearing corporation. The broker applies a 'haircut' (e.g., 20%) and gives you the remaining 80% value as trading margin for F&O or intraday equity.

Margin Calculator 2026 – Trading Leverage & Risk Estimato...

The Margin Calculator helps traders understand margin requirements, leverage, and potential profit/loss for leveraged positions. Margin trading allows you to control larger positions with less capital, but also amplifies both gains and losses—making it essential to calculate risks before trading.

How Does the Margin Calculator Work?

Margin is the collateral you deposit with your broker to open leveraged positions. The calculator shows how much margin you need, the leverage you get, and potential profit or loss based on price movements.

Margin Required = (Trade Value × Margin %) ÷ 100

Where:

• Trade Value = Number of Shares × Stock Price
• Leverage = 100 ÷ Margin Percentage
• Potential P&L = Trade Value × Price Change %

Initial Margin: Minimum amount to open a position (typically 20-50%)
Maintenance Margin: Minimum balance to keep position open
SPAN Margin: For F&O, calculated using portfolio risk algorithm
Exposure Margin: Additional margin on top of SPAN for F&O

Example: Margin Trading Calculation

Vikram wants to trade Reliance shares worth ₹1,00,000 using margin.

Trading Details:
• Trade Value: ₹1,00,000
• Margin Required: 20%
• Stock Price: ₹2,500

Calculations:
• Margin Needed: ₹1,00,000 × 20% = ₹20,000
• Leverage: 100 ÷ 20 = 5x
• Shares Can Trade: 1,00,000 ÷ 2,500 = 40 shares

If stock rises 5%:
• Profit: ₹1,00,000 × 5% = ₹5,000
• Return on Margin: ₹5,000 ÷ ₹20,000 = 25%

Vikram earns 25% on his margin for a 5% stock move—but losses are equally amplified!
