MGC position size calculator

One MGC contract moves 1 USD per tick of 0.1, which is 10 ounces. Futures trade in whole contracts, so this page sizes in contracts rather than in fractions of a lot: give the calculator your account size, the percentage you are willing to lose and the stop distance, and it returns how many contracts put exactly that much at risk, always rounded down.

Checks the trade against your challenge drawdown. The tighter of the two limits wins: staying inside the daily rule is useless if the overall one is already spent.

Broker settings

Every broker defines its own contract and pip. If the size does not match your platform, adjust these once and save them as a template.

What makes MGC different

Micro gold is a tenth of the full GC contract: 10 troy ounces instead of 100, ticking in 0.10 steps that are worth $1.00 each. Compared with spot XAUUSD at a CFD broker it removes the argument about what a pip is — the exchange defines the tick and everyone uses the same one. Read the price the same way you read spot gold: a $1 move in the metal is $10 on one contract. The trade-off is that gold routinely swings $20 or $30 in a session, so a stop that survives the noise puts $200 to $300 per contract on the line.

A worked example

  1. Risk in money: a 10 000 USD account risking 1% puts 100 USD on the line.
  2. Stop distance in price: 100 ticks × 0.1 = 10.
  3. Loss per contract: 10 × 10 = 100 USD.
  4. Contracts: 100 ÷ 100 = 1, rounded down to 1.

The example assumes an account in USD. If yours is in another currency, every figure above gets multiplied by the rate from USD to your currency, which the calculator applies automatically.

Frequently asked questions

How much is one tick worth on MGC?

One contract is 10 ounces, so a tick of 0.1 is worth 1 USD and 10 ticks make a one-point move, worth 10 USD. Two contracts double it and three triple it; there is no fraction of a contract to go below one. If your account is not in USD, multiply by the current rate from USD to your account currency.

How many MGC contracts should I trade?

Decide the loss first — most traders cap it at 1% to 2% of the account per trade — then divide that amount by the loss per contract at your stop distance. The calculator above does exactly that and rounds down, because a partial contract does not exist. If the answer comes out below one, the trade is too big for the account at that stop: widen the stop budget or fund more, never round up.

Is one MGC lot the same as one contract?

Yes. Futures have no mini or micro fraction: the minimum size is one contract and every step up is another whole contract, so the lot size the calculator returns is the number of contracts to send to the exchange. That is why the broker settings above start at a minimum lot of 1 and a lot step of 1 for this symbol.

How much margin does one MGC contract need?

This page starts from 1,300 USD per contract, the order of magnitude of the exchange's initial margin, but it is not a fixed number: the CME revises it as volatility changes, and each broker sets its own day-trading margin, often a fraction of that for positions closed before the session ends. Take the exact figure from your platform and type it under "broker settings" — it changes how much cash the position ties up, not the risk on the trade.
