VAR + ELM intraday margin on Zerodha

From WebNotes, a public knowledge base. Last updated . Reading time ~4 min.

VAR + ELM is the margin framework applied to equity intraday (cash segment) trades on Zerodha (and any Indian broker). For F&O, SPAN + Exposure is the framework; for equity cash, it’s VAR + ELM.

VAR (Value at Risk)

VAR is the volatility-based margin component per scrip:

  • Scrip-specific historical volatility.
  • 99% confidence interval.
  • 1-day horizon.
  • VAR margin = price level x VAR factor.

For a Rs 100 large-cap scrip with 1.5% daily volatility, VAR might be ~9% of notional.

ELM (Extreme Loss Margin)

For equity intraday: ELM is the additional buffer beyond VAR. Typically 2-3% of notional.

ComponentApproximate range
VAR9-15% for liquid large-caps
ELM2-5%
Total intraday margin11-20% (leverage 5-9x)

Effective leverage

Intraday leverage for equity = 1 / (VAR + ELM ratio).

Scrip typeApproximate intraday marginApproximate leverage
Liquid large-cap12-15%6.5-8x
Mid-cap15-22%4.5-6.5x
Small-cap20-30%+3-5x
Highly volatile / surveilled30-50%2-3x

For a Rs 10,000 capital, you can trade Rs 60,000-80,000 of liquid large-cap intraday.

How Zerodha implements

Zerodha (and all Indian brokers) consume the exchange-published VAR + ELM file:

CNC vs MIS

  • CNC (delivery): 100% margin required (no leverage); no VAR + ELM relevance.
  • MIS (intraday): VAR + ELM applies; effective leverage 5-9x for large-caps.

Intraday margin can increase

The VAR file refreshes:

  • End of trading day (most common).
  • During severe volatility events.

If VAR rises during the session (post-refresh), open MIS positions’ margin requirement also rises. This can trigger margin shortfall for tight positions.

See Intraday margin increases on volatile days for more.

Pre-peak-margin vs post-peak-margin

Pre-2020: Brokers offered up to 20x intraday leverage via broker-extended credit on top of VAR + ELM.

Post-Phase-4 (Sep 2021): Only exchange VAR + ELM margin; no broker leverage.

Comparison with international

MarketIntraday equity leverage
India (post-peak-margin)5-8x typical
US (FINRA)4x for pattern day traders
UKLess common; brokers vary
SingaporeSimilar to US

India’s intraday leverage is comparable to international norms post the SEBI tightening.
