Dollar Risk Boundary
The rule focuses on how much money is at risk in the trade, not just how many contracts are open.
Futures Risk Per Trade Calculator
Enter your own budget and stop distance to compare estimated dollar risk with whole-contract sizing. Starting values are illustrations, not recommended settings. Nothing here changes your account or places an order.
Micro E-mini S&P 500 (MES): $5.00 per point; 0.25 points per tick; $1.25 per tick. Stop distance is the absolute difference between entry and protective stop, for either a long or a short.
Estimated risk for proposed contracts

Stop used: 10 points / 40 ticks. Stop-only risk per contract: $50.00. Including your allowance: $50.00.
The proposed contracts fit your entered risk budget under these assumptions.
Estimated risk = contracts × (stop points × dollars per point + per-contract cost allowance). Budget-based count = budget ÷ estimated risk per contract, rounded down. An optional cap can only reduce that count.
Costs default to $0; enter your own round-trip commissions, fees, and slippage allowance. Stops do not guarantee a fill price or maximum loss. This is not a margin, buying-power, account-eligibility, or prop-firm compliance check. A contract cap here applies only to the selected instrument; it does not convert mixed micro/mini positions or reserve capacity for other open trades.

Choosing contract count? See the futures position sizing examples for rounding and contract caps. A per-trade estimate is separate from your daily loss limit, which addresses session-wide losses.
Stop Distance Matters
A wider stop can turn a normal position size into a larger risk event.
Pre-Trade Discipline
The trader defines the risk limit before the setup feels urgent.
Worked Example: MES Stop Distance and Dollar Risk
Suppose an MES entry is 6,000 and the protective stop is 5,990. The 10-point distance at $5 per point is $50 of stop-only risk per contract. Two contracts produce $100 of stop-only risk. These are illustrative prices, not a trade recommendation.
If you enter a $3 round-trip fees and slippage allowance per contract, the estimate becomes 2 × ($50 + $3) = $106. A $100 budget therefore fits one contract, not two. The allowance is hypothetical; use your own costs.
Widening that stop to 20 points doubles stop-only risk to $100 per MES contract. Holding the same two contracts would then mean $200 before costs, despite no change in position size.
Points Versus Ticks: MNQ and NQ Example
For MES, ES, MNQ, and NQ outright futures, one tick is 0.25 index points, so a 20-point stop is 80 ticks, not 20 ticks. The calculator converts between these units and rounds fractional ticks upward.
At a 20-point stop, one MNQ contract has $40 of stop-only risk ($2 per point), while one NQ has $400 ($20 per point). That difference is why the instrument must be part of the calculation. All examples exclude costs unless an allowance is specified.
Why Contract Count Is Not Enough
A trader can stay within a max contract limit and still take too much dollar risk if the stop is placed far away. That is why max risk per trade is its own rule.
The rule gives the trader a separate boundary for the amount of risk attached to one decision. It is especially useful when volatility changes and the same number of contracts no longer means the same risk.
How Risk Expands During a Trade
Risk can expand when a trader widens the stop, increases size, or enters without a clear protective order. These behaviors often overlap with emotional trading, but the risk rule itself stays specific: the trade is above or below the configured dollar limit.
TradeReign's max risk per trade rule is designed to help enforce the user's predefined dollar-risk boundary in supported workflows.
Where This Rule Fits
Max risk per trade pairs with stop enforcement and stop protection. Stop enforcement helps address trades without a required stop, while max risk per trade addresses whether the stop distance and position size create too much risk.
It also pairs with max daily loss. One rule controls the risk of an individual trade. The other controls total session damage.
Max Account Risk Versus Single-Trade Risk
TradeReign also includes a max account risk / exposure rule. That rule looks across open positions instead of focusing on only one setup. In stop-risk mode, missing protective stops can count as unmeasurable risk because the app cannot estimate the open risk cleanly.
The exposure mode is different again: it caps estimated margin exposure using per-contract buying-power estimates. That can help control size, but it should not be read as a true maximum-loss calculation.

FAQ
Common Questions
How do you calculate dollar risk on a futures trade?
Multiply the stop distance in points by the contract's dollar value per point and the number of contracts. Add estimated round-trip fees and slippage. For example, two MES contracts with a 10-point stop have $100 of stop-only risk before costs. Actual losses can exceed the estimate.
Does a stop order guarantee the calculated maximum loss?
No. Gaps, slippage, liquidity, and execution problems can cause a different outcome. The calculator estimates stop-defined risk; it does not guarantee a fill price or recommend an appropriate budget.
What is max risk per trade?
Max risk per trade is the largest dollar amount a trader allows themselves to risk on a single trade. In futures, that amount depends on contract size, entry price, stop placement, and the instrument's point value.
Is max risk per trade the same as max position size?
No. Max position size controls the number of contracts. Max risk per trade controls the estimated dollar risk of the setup. A small contract count can still carry too much risk if the stop is far away.
How does TradeReign use max risk per trade?
TradeReign can monitor supported workflows for user-defined max risk rules and respond according to the user's configured behavior when estimated trade risk, total open risk, or configured exposure limits are exceeded.
