Risk-reward Ratio

Ratio of planned loss to profit

Risk-reward Ratio compares planned loss with planned profit. A clear notation specifies the order of the quantities, monetary amounts and costs. The ratio alone says nothing about how often the target will occur and guarantees neither an exit price nor a profitable strategy.

Risk-reward Ratio is the ratio of a trade's predefined loss and profit magnitudes at specified exits. The direction of the ratio must be stated, and planned values distinguished from actual fills and statistics of completed trades.

Risk-reward Ratio compares the planned loss with the planned profit of the same trade. CME presents it as one perspective on risk management. The notation must say which quantity comes first: risk to reward is not the same number as reward divided by risk. In this entry, risk is the positive magnitude of a loss and reward is a positive profit; an actual negative outcome is shown with its sign. Here the word reward does not mean an expected or guaranteed return. [1]

For a simple long spot position, the planned price loss is quantity multiplied by the difference between entry and the losing exit. Price profit uses the difference between the profitable exit and entry. CME emphasizes both stop distance and the value of a price tick when sizing a position. The same geometric ratio can therefore represent very different monetary exposures. Contracts require their multiplier and payoff method; the simple spot formula cannot be transferred to options or an inverse contract without checking. [2]

Purchase and sale fees reduce the profitable alternative and increase the losing one. It must be stated whether they are already included in the compared amounts. Coinbase distinguishes maker and taker fees by individual fills; actual costs are therefore not a universal constant for every order. Financing and other charges belong in the calculation when applicable to the product. Spread and slippage included in actual prices must not be counted twice. [5]

In its discussion of mathematical expectation, CME combines win and loss frequencies with their average sizes. Planned price distances do not determine those frequencies. Moving the target farther away can increase the calculated profit, but cannot establish that the probability of reaching it remains the same. A break-even threshold can be derived only for an explicitly specified outcome model. It is a condition on an unknown success rate, not an estimate of it or confirmation of a trading edge. [3]

For stock stop orders, FINRA warns that the trigger price is not a guaranteed execution price; a limit variant may not execute at all. Coinbase likewise distinguishes market and limit execution according to the available book and product restrictions. Losing and profitable exits are therefore assumptions of the plan that must be separated from actual fills. A ratio calculated from drawn levels guarantees neither a loss cap nor target execution during price gaps or insufficient liquidity. [4] [6]

If part of a position is sold earlier and the remainder differently, the whole position cannot be evaluated solely by its most distant target. Coinbase describes partial fills and different ways to retain or cancel the remainder. The calculation should therefore use the quantity and price of each closed part and allocated costs. No fill or an open remainder is not a completed loss or win. The planned ratio and the empirical ratio of average realized profits to losses are different measures. [6] [3]

In discussing hypothetical results, NFA highlights the benefit of hindsight and imperfect representation of liquidity, slippage and behavior during losses. Selecting only charts where a distant target worked therefore does not demonstrate an advantageous rule. Evaluation needs to distinguish predefined conditions from changes based on a known outcome and disclose unexecuted trades and costs. The fictional calculation here explains definitions; it is neither a historical test nor a strategy's performance. [7]

In a risk management plan, CME distinguishes the risk of an individual trade, simultaneous positions and the account's overall exposure. The ratio alone does not show position size, holding period, liquidity or joint movement of multiple exposures. Comparisons require matching currency units and a clear cost scope, while also showing actual monetary amounts. The definition does not imply a universally correct ratio. Review continues with probabilities, the outcome distribution and the ability to bear losses. [1] [3]

The same exit prices, a different ratio after costs

This original hypothetical model uses the same fully paid long position of 0.25 BTC with entry at 100000 USD/BTC, an acquisition value of 25000 USD before costs. Alternative A assumes a complete sale at 96000 USD/BTC and alternative B at 108000 USD/BTC. We explicitly assume exact complete fills, no further slippage and total purchase and sale costs of 100 USD in each alternative. Before costs, the loss magnitude is 1000 USD and profit is 2000 USD: risk to reward is 1:2 and reward divided by risk is 2. After costs, the loss magnitude is 1100 USD and profit is 1900 USD: risk to reward is 11:19 and reward divided by risk is 19/11, approximately 1.7273. The chart shows signed net outcomes [-1100, 1900] USD for alternatives A and B; these are not two consecutive transactions. Only under the additional assumption that every completed trade ends in exactly one of these alternatives with the same quantity and costs does the zero-average-result threshold equal the loss divided by the sum of profit and loss. Without costs it would be 1/3, approximately 33.3333%; with costs it is 11/30, approximately 36.6667%. This threshold is neither an observed win rate nor a probability of reaching the target. With different fills, partial exits or additional outcomes, the described two-outcome model is insufficient. Taxes, financing and time value are excluded; costs are not an exchange fee schedule, and the planned losing exit is not a guaranteed maximum loss.

For the clearest picture, read this entry together with Position Sizing, Stop-loss, Take-profit, Slippage, Risk Management. The reverse links also lead from Expectancy.

01Does a high reward-to-risk ratio prove a profitable strategy?

No. Besides outcome size, occurrence frequency, costs and actual execution matter. A more distant target can improve the written ratio but does not by itself establish the same chance of reaching it.

02Why does the break-even threshold change when costs are included?

Costs subtract from the profitable alternative and add to the losing one. A model with two fixed outcomes therefore needs a higher proportion of wins to average zero. This calculation applies only under the stated assumptions and is not a forecast of the win rate.
