Intraday (Day-Trade) Margin in Futures: How It Works and the Risks
By Kamal Chelliah · Published November 2, 2026 · Last reviewed November 2, 2026
Educational only, not financial advice. Futures trading involves substantial risk of loss and is not suitable for everyone. Past results do not guarantee future results.
Many futures brokers advertise a low "intraday" or "day-trade" margin. It can look like a bargain, but it changes the risk in ways beginners often miss. This guide explains how it works in general. Rules differ by broker, so confirm the details with yours.
Overnight margin vs. intraday margin
| Overnight (exchange) margin | Intraday (day-trade) margin | |
|---|---|---|
| Who sets it | The exchange sets the minimum; brokers can charge more | Your broker sets it, usually lower |
| When it applies | Positions held past the broker's cutoff | Positions opened and closed within the session |
| Purpose | Cover risk while the market is closed or less liquid | Let day traders use less capital for short-term positions |
Margin is a deposit held against possible losses, not a fee and not a down payment. See futures margin explained.
Why lower margin means more risk
- A smaller deposit lets you open more contracts, which increases leverage
- The same price move now changes your account balance by a larger percentage
- Losses can still exceed your deposit
- Margin is not a safe position size. Size by risk per trade, not by what margin allows
The cutoff-time risk
If you hold a position past your broker's cutoff time, the higher overnight margin may apply. If your account balance is below that requirement, the broker may close the position automatically, at whatever price is available. That can lock in a loss at a poor price. Know your broker's cutoff and plan to be flat before it.
A hypothetical illustration
Hypothetical numbers only. If one contract needs $500 of intraday margin and $2,000 overnight, a $3,000 account might open five contracts intraday but could only hold one overnight. A trader who is five contracts long near the cutoff has to reduce quickly, or the broker may do it for them.
Questions to ask your broker
- What are the current intraday and overnight margins for the contracts I trade?
- What time does intraday margin end each day?
- What happens if my balance falls below margin: margin call, or automatic liquidation?
- Can intraday margin change without notice, for example around news events?
- Are there extra fees for liquidation?
A safer way to use it
- Decide your risk per trade in dollars first
- Set the stop, then size the position from the stop distance
- Treat intraday margin as the minimum your broker allows, not as your size
- Flatten before the cutoff unless you have planned for overnight margin

Frequently asked questions
What is intraday margin in futures?
A lower margin requirement some brokers offer for positions opened and closed within the same session.
Who sets intraday margin?
Your broker. The exchange sets the minimum margin for each contract, and brokers can require more or offer lower margin for day trades.
What happens if I hold past the cutoff?
Overnight margin may apply, and if your balance is too low your broker may close the position automatically.
Is low margin a good thing?
It lets you use less capital, but it makes it easier to take a position larger than you can afford. Size by risk, not by margin.
