Listen closely, retail participants often stare at the margin screen and wonder why the numbers dance — used margin, available margin, and the mysterious e‑margin are not the same beast. In real trading desks we treat each figure as a separate lever that can either protect your capital or blow it up if misunderstood. Let me break it down the way we do it on Dalal Street, with broker‑specific screenshots in mind.

1. What Is Used Margin in Angel Broking (and Every Other Broker)
Used margin is the actual capital that gets blocked the moment you open a position — be it an equity delivery, an intraday trade, or an F&O contract. Angel One shows it under the “Used Margin” column on the Funds page, and it updates in real‑time as MTM (mark‑to‑market) profits or losses flow in. If you hold a margin trading facility MTF position, the used margin includes both the initial margin and any additional MTM debit.
2. Available Margin — The Breathing Room You Actually Have
Available margin is simply your net free cash plus any approved collateral (liquid stocks, ETFs, or sovereign gold bonds) minus the used margin. On Angel One it appears as “Available Margin” and on Zerodha as “Free Cash” plus “Collateral Value”. Remember, a sudden spike in MTM loss can shrink this number faster than a monsoon flood, so keep a buffer of at least 20‑25 % above your peak margin requirement.
3. E‑Margin — The HDFC Securities & Angel One Twist
E‑margin (electronic margin) is a broker‑specific facility that lets you pledge approved securities electronically without moving them to a separate demat account. In HDFC Securities it shows up as “E‑Margin” under the Limits tab, while Angel One labels it “Collateral Margin”. The key difference: e‑margin is *not* cash; it’s a borrowing limit that can be revoked if the collateral value falls below the haircut threshold.
4. Peak Margin, MTM & Collateral — The Common Confusion Points
Peak margin is the highest margin your position demanded during the day — SEBI now mandates brokers to report this for every client. MTM (mark‑to‑market) adjusts used margin intraday, but the peak margin figure stays as a regulatory snapshot. Collateral (stocks, MF units, G‑Secs) can be used to meet both used and peak margin, yet many retail traders forget that haircut percentages differ across brokers (e.g., 20 % for large‑cap stocks on Angel One vs 25 % on Upstox).
| Broker | Used Margin Label | Available Margin Label | E‑Margin / Collateral Label | Peak Margin Visibility |
|---|---|---|---|---|
| Angel One | Used Margin | Available Margin | Collateral Margin | Shown in “Margin Report” |
| HDFC Securities | Used Margin | Free Cash + Collateral | E‑Margin | Daily Peak Margin PDF |
| Zerodha | Used Margin | Free Cash + Collateral Value | Collateral Margin | Console → Margin → Peak |
| Upstox | Used Margin | Available Margin | Collateral Margin | Reports → Peak Margin |
Actionable Investor Takeaways
- Check your used margin *before* placing a new order — a quick glance at the Funds page saves you from a margin call.
- Maintain a collateral buffer of at least 25 % above the peak margin requirement; haircuts can change overnight.
- Use the NSE F&O margin calculator and the SPAN margin calculator to simulate worst‑case MTM scenarios.
- Enable SMS/email alerts for “Margin Utilisation > 80 %” on every broker platform you trade.
Frequently Asked Questions
1. What is the difference between used margin and available margin?
Used margin is the capital currently blocked for open positions, while available margin is the free cash plus approved collateral minus that used margin. Think of used margin as “money already spent” and available margin as “money you can still spend”.
2. How does e‑margin work in HDFC Securities?
E‑margin lets you pledge eligible securities electronically to get a borrowing limit; the pledged shares stay in your demat but are marked as collateral. If the market value drops below the haircut, HDFC can square off positions to restore the margin.
3. Why does peak margin matter for a retail trader?
SEBI uses peak margin to assess whether a broker is collecting enough upfront margin from clients. If your peak margin exceeds the collected margin, the broker may issue a margin call even if your end‑of‑day used margin looks comfortable.
4. Can I use mutual fund units as collateral for margin across all brokers?
Most brokers (Angel One, Zerodha, Upstox, HDFC Securities) accept liquid mutual fund units, but the haircut and eligible fund list differ. Always verify the broker’s collateral policy before pledging.
