MCX commodity trading in India: a beginner's guide

India has three broad public markets for retail traders. Cash-market equity on NSE and BSE. Equity derivatives (F&O) on NSE. And commodities on MCX.

The first two get almost all the retail attention. Commodities remain a smaller, more specialised segment — which means there is less noise, fewer YouTube gurus, and often better setups for a disciplined trader. It also means new participants often walk in without knowing what makes the segment different from equity.

This piece is the primer we would give a friend who wanted to trade their first gold or crude contract.

What "MCX" is

The Multi Commodity Exchange of India Limited (MCX) is India's largest commodity derivatives exchange. It is regulated by SEBI, incorporated in 2003, and headquartered in Mumbai.

MCX offers futures and options contracts on a range of commodities in three broad buckets:

• Bullion — gold, silver, and their smaller-lot variants (Gold Mini, Silver Mini, Gold Guinea, Gold Petal).
• Base metals — copper, zinc, lead, aluminium, nickel.
• Energy — crude oil, natural gas.

Some agricultural commodities also trade on NCDEX (National Commodity & Derivatives Exchange), but MCX is the exchange most retail traders start with.

What actually gets traded

You do not buy "gold" on MCX in the sense of taking home a physical bar. You buy a futures contract — an agreement to buy or sell a defined quantity of the commodity at a defined price on a defined future date.

Contract specifications matter. For each commodity, MCX defines:

• Lot size — the standardised quantity per contract.
• Tick size — the minimum price movement.
• Expiry cycle — when the contract settles.
• Delivery / settlement type — cash-settled or physically deliverable.
• Trading hours — commodities trade longer than equities, often up to 11:30 PM IST for energy and metals, tracking international benchmarks.

For example, one MCX Gold contract is 1 kg. One Gold Mini contract is 100g. Crude oil futures are 100 barrels. Natural gas is 1,250 mmBtu. These specifications drive the notional value of each trade, and therefore the margin required and the rupee move per tick.

Do not trade a commodity contract without reading its specification sheet. You need to know exactly what a one-tick move costs you before you place the trade.

How commodities differ from equity

If your only trading experience is cash-market equity, five differences will hit you immediately when you enter commodities.

1. Leverage is baked in

Commodities are traded as futures. You pay only initial margin, not the full contract value. On a 1 kg gold contract worth roughly ₹65 lakh at ₹65,000 per 10 grams, the initial margin might be ₹3-5 lakh depending on volatility. That is 15-20x leverage.

This is F&O-like leverage. It amplifies both wins and losses proportionally. Position sizing matters more here than it does in delivery equity.

2. Trading hours are longer

Equity closes at 3:30 PM. Base metals and bullion typically trade until 11:30 PM. Crude and gas often to 11:30 PM as well. This tracks international commodity price discovery — MCX prices move with Comex, Nymex and LME rather than in isolation.

The practical implication: overnight risk in commodities is not really "overnight" — the position keeps moving after equity markets close. If you go home flat in equities and long crude, you are still trading crude at 10 PM.

3. International news dominates

An equity trade is driven by company-specific news, sector news, or broad market sentiment. A commodity trade is driven by:

• OPEC decisions (crude).
• US inventory data (crude, natural gas — weekly EIA reports at 8 PM IST).
• US Fed policy (bullion — dollar strength inversely affects gold).
• Chinese industrial demand (base metals).
• Geopolitical shocks (energy, precious metals).

Traders who track only Indian domestic news will be blindsided repeatedly. Commodities require awareness of international calendars.

4. Fewer instruments, more focus

NSE has 2,000+ listed equities. MCX has a handful of actively traded commodities. This is a feature, not a bug — you can develop a real edge on 3-4 commodities in a way you cannot on 200 stocks.

Most retail commodity traders focus on some subset of: Gold, Silver, Crude, Natural Gas, Copper. Depth over breadth is the norm.

5. Cash settlement is common but not universal

Most retail commodity trades close before expiry and settle in cash. But some contracts — bullion in particular — can be delivered physically if held to expiry. If you accidentally hold a Gold contract past its expiry, you can find yourself obligated to take delivery of 1 kg of physical gold.

This never happens by accident to a disciplined trader — you close or roll the position before expiry. But it is a real risk for a distracted one.

Position sizing for commodities

Same equation as everywhere else. Same equation as the one we walked through in how to read a research call:

1. Define your risk budget for the trade — a fixed rupee amount.
2. Compute per-lot risk — (entry price minus stop-loss) times contract lot size.
3. Position size = risk budget divided by per-lot risk.

Worked example on Crude Oil futures. Contract lot = 100 barrels. Entry ₹7,200. Stop ₹7,120. Per-lot risk = (7,200 - 7,120) × 100 = ₹8,000. If your risk budget is ₹8,000, you trade one lot. If your risk budget is ₹4,000, you cannot trade this call safely — the lot size does not fit your account.

This is where many new commodity traders get in trouble. They see a compelling setup, they trade one lot because "one lot is the smallest size", and they were never sized for that contract in the first place. If a contract's minimum lot size does not fit your risk budget, that contract is not for you today. Trade a Mini variant if available, or wait until your account has grown into the notional.

Which commodities to start with

If you are new to MCX, do not start with Natural Gas. It is the most volatile contract on the exchange and will teach you expensive lessons at high speed.

Reasonable starting points:

• Gold Mini — smaller notional than the main Gold contract, trades similarly, less capital-intensive.
• Silver Mini — same reasoning as Gold Mini, higher volatility so tighter risk discipline needed.
• Copper — economically driven, decent intraday liquidity, less news-shock driven than energy.

Save Crude Oil and Natural Gas for after six months of trading discipline in the calmer contracts. Both can move 5-10% in a single session on inventory news or geopolitical events. Newcomer accounts do not survive those days.

MCX in the CapitalBridge segment mix

Our research desk publishes MCX commodity calls under the Commodity Pro segment. Every call is structured the same way as our equity and F&O calls — segment, side, entry, target, stop-loss — so the trading workflow does not change across segments. What changes is the specification of the underlying and the sizing math around lot size.

You can subscribe to Commodity Pro alone if MCX is your primary market, or take All-Access to trade commodity setups alongside equity and F&O calls.

The one thing to internalise

MCX is not "smaller F&O". It is a different market with its own rhythm — international news drive, longer hours, larger notionals per lot, real physical-delivery consequences at expiry.

Treat it with the same discipline you would treat any leveraged market: know the contract spec, size against the stop, honour the exit. Commodities reward focused, patient traders. They punish tourists more brutally than equity does — because leverage plus international news plus long hours is a combination that leaves no room for laziness.

Start small. Read the contract specs. Trade one commodity for three months before adding a second. That is the disciplined path in.
