Direct answer
Risk Reward Target is measured by turning the idea into a small set of fixed, recordable inputs—mainly the distances (or amounts) between an entry price and a stop-loss level, and between the same entry price and a take-profit level—then comparing those planned distances to what actually happened using timestamps and fill prices.
In other words: you measure it by (1) defining the fields used for the calculation, (2) capturing the exact prices and times where calculations start and end, and (3) documenting the assumptions so that another person can reproduce the same measurement from your records.
Mechanism and definition
A practical measurement starts with separating planned values from realized values.
1) Planned risk and planned reward distances
Define an entry reference price (for example, the fill price of a trade). Then define:
- Stop level (stop-loss price)
- Target level (take-profit price)
From these, compute a planned risk distance and a planned reward distance using one consistent method, such as absolute price difference or direction-aware movement.
A common measurable form is a ratio:
- Planned Risk Reward Target ≈ (Reward distance) ÷ (Risk distance)
Important: the calculation only makes sense if the stop and target are defined relative to the same entry reference (and for the same trade direction).
2) Realized risk and realized reward (what actually happened)
To measure what the market and execution delivered, you need exit information:
- the exit type (stopped out, took profit, or other exit)
- the exit fill price
- the timestamp(s) for the entry and exit
Then compute realized distances relative to the entry reference.
3) Time alignment using timestamps
Risk Reward Target is not only about “how far” but also “when.” Record at least:
- entry timestamp (time of the entry fill or the order submission, but choose one and stick to it)
- exit timestamp (time of the exit fill)
Using timestamps lets you compare trades fairly and helps identify whether the target was effectively measured over different market regimes.
Evidence or example (with explicit assumptions)
Assume the following for illustration only:
- Entry fill price: 1.1000
- Stop-loss level: 1.0980
- Take-profit level: 1.1040
- Trade direction: long
Step A: compute planned distances.
- Planned risk distance = 1.1000 − 1.0980 = 0.0020
- Planned reward distance = 1.1040 − 1.1000 = 0.0040
- Planned Risk Reward Target = 0.0040 ÷ 0.0020 = 2.0
Step B: compare planned vs realized. Now suppose the realized exit occurs at 1.0982 due to execution variation.
- Realized risk distance = 1.1000 − 1.0982 = 0.0018
- Realized outcome ratio (based on actual stop reach) would be different from the planned 2.0.
If you also record timestamps, you can document whether the exit happened quickly during fast price movement or later after conditions changed. This is a measurement requirement, not a prediction.
Limitations and risks
1) Execution and measurement mismatch
A key failure mode is using non-matching prices. If you measure planned risk using order levels but realized risk using actual fills (or vice versa), your comparison may be mathematically inconsistent.
2) Slippage, fees, and spreads
Real trading typically involves transaction costs. Even if you measure distances correctly in price terms, costs can change outcomes in account terms.
Because these elements vary by venue, instrument, and moment in time, measurements should state whether they are:
- price-distance based (ignoring costs)
- cost-aware (including commissions/fees, and in some cases spread/financing effects)
3) Partial fills and stop/target behavior
Another limitation is partial fills. If only part of the position closes at the stop/target, realized risk and reward for the whole intended position may not match a single ratio.
4) Changing market conditions
Historical relationships do not guarantee future results. Also, volatility can change while the trade is open, affecting how often stops or targets are reached within a given time window.
Verification and next question
To independently verify your Risk Reward Target measurement, another person should be able to reconstruct it from your recorded fields:
- entry reference price (fill price vs order price, stated explicitly)
- stop and target levels used for the plan
- the formula used (ratio definition and distance method)
- entry and exit timestamps and exit fill prices
- what was done about partial fills and whether costs were included
