Margin and Contract Lifecycle · Futures Trading Guide
An intraday collateral concession changes funding access, not the size of a contract’s price risk. Position size must be decided independently.
Measure leverage against equity
For a simple linear contract, notional exposure divided by account equity gives a useful leverage measure. It is not a full risk model because different markets have different volatility. A $100,000 position in a $5,000 account has twenty times notional exposure. A one percent adverse move in the underlying contract price represents about $1,000, or twenty percent of that account, before costs.
Do not size from the minimum deposit
Suppose a broker hypothetically permits one contract with $500 intraday collateral. That does not mean the worst loss is $500. If its multiplier is $50 per point, a twenty point adverse move costs $1,000. Buying four contracts because $2,000 appears available multiplies that same move to $4,000. The exchange and broker can still require more collateral.
Check the transition out of the session
Intraday concessions may end at a specified cutoff and may be withdrawn during events. A position that meets the morning requirement can fail the later requirement without any price movement. Record the exact cutoff, timezone, holiday treatment and the broker’s liquidation policy. Treat an unfilled closing order as an open position, not as proof that the trade ended on time.
Set an independent cash budget
Estimate planned loss from an exit distance, then add costs and a realistic adverse execution scenario. Check the larger gap scenario separately because stops cannot guarantee a fill price. Select a smaller contract or no trade when the minimum unit exceeds the budget. Keeping more reserve than the broker requires is a funding decision, not protection against unlimited market movement. This distinction is essential when comparing brokers that advertise very different minimum margins.
Try it yourself
A $2,500 account controls $50,000 of futures exposure. What is the approximate effect of a two percent adverse move for a linear contract?
Show the worked answer
The move loses about $1,000 before costs, equal to forty percent of starting equity. A low intraday margin requirement would not change this result.
