Risk-to-reward, explained without the hype.

A risk-to-reward ratio compares a trade’s planned potential loss with its hypothetical potential gain. It is a simple comparison tool, not a forecast or a guarantee about what a forex trade will do.

01 / The basic idea

Compare planned loss with hypothetical gain

In plain language, the risk-to-reward ratio asks: how much potential loss is being compared with how much potential gain? The risk side is the amount a written plan could lose if its loss boundary is reached. The reward side is a hypothetical amount if its potential-gain target is reached.

A ratio written as 1:2 means the hypothetical gain in the comparison is twice the planned loss. It does not mean the gain is twice as likely, that the trade will reach the target, or that the ratio is right for any reader.

02 / A clear arithmetic example

One hypothetical plan: $100 compared with $200

The figures below are invented for explanation only. They are not a forecast, a suggested position size, an entry or exit instruction, a risk limit, or a promise of a result.

Clearly hypothetical educational example

Hypothetical planned loss: $100
Hypothetical potential gain: $200
Arithmetic: $100 : $200 = 1 : 2

This only shows how the labels and arithmetic fit together. It does not say that either amount will occur, that the target will be reached, or that a trade should be taken.

03 / What each side means

Three planning ideas sit behind the comparison

Planned loss boundary

A level or condition in the written plan where the trade idea would be considered invalid. The distance from entry and the position size can be used to estimate a potential loss, but the actual fill may differ.

Potential-gain target

A hypothetical price level used to compare a possible gain with the planned loss. Reaching it is uncertain; the target is not a forecast, promise, or instruction to hold a position.

The comparison

The ratio puts those two planned amounts side by side. It says how large the hypothetical gain is compared with the hypothetical loss; it does not say whether a trade is suitable or likely to succeed.

04 / What the ratio leaves out

A comparison cannot control execution

A ratio can make two planned amounts easier to compare, but it is incomplete. The actual result can change because of market conditions, trading costs, and the way an order is executed. It also says nothing by itself about the probability of a gain or loss.

Spread, commission, swap or financing, and other costs can reduce a result or change the comparison.
Slippage and gaps can make an exit happen at a different price from the planned loss boundary.
Leverage can increase the market exposure relative to a trader’s own capital and can magnify losses.
Liquidity and fast or thin markets can affect available prices and execution.
The ratio does not describe the chance of reaching either level, and it cannot predict an actual result.
