The risk reward ratio compares what you stand to lose on a trade with what you stand to gain. A ratio of one to two means you risk one unit to potentially make two, while one to three means you risk one unit to potentially make three. This single number shapes your whole trading business, because it determines how often you need to be right in order to break even. A trader with a strong ratio can be wrong more often than right and still come out ahead. Many trading platforms let you visualise the ratio directly on the chart with a position tool, which makes it much easier to judge a trade's ratio before committing any money.

Many beginners focus only on win rate, but win rate alone tells you nothing. A trader who wins eighty percent of trades but takes tiny profits and huge losses can still lose money overall, while a trader who wins forty percent of trades with a one-to-three ratio can be profitable. The ratio and the win rate work together: your expectancy is the average win multiplied by your win rate, minus the average loss multiplied by your loss rate. Positive expectancy is the real goal. A frequent beginner error is moving the stop loss further away after entering a trade, which silently destroys the planned ratio and turns a disciplined trade into a hope-based one.

Take a concrete example. You buy a currency pair with a stop loss twenty pips below your entry and a target forty pips above it — a one-to-two ratio. If you risk a fixed amount per trade, each winner pays for two losers. Over ten trades with four winners and six losers, you win four times your risk amount and lose six times, leaving a net loss — so this ratio alone is not enough without a win rate above one in three. The maths keeps you honest about what your strategy must deliver. Trailing a stop loss as price moves in your favour can protect profits, but it also changes the effective ratio, so it should be part of your tested plan rather than an improvised decision.

Now stretch the target to sixty pips for a one-to-three ratio with the same twenty-pip stop. The same four winners out of ten now pay twelve units against six units lost, a comfortable profit. But there is a trade-off: wider targets get hit less often, so your win rate will usually fall as your ratio rises. The art is finding the combination your strategy actually achieves, not the combination that looks best in a spreadsheet. When comparing two potential trades, the one with the better ratio is not automatically superior, because a trade with a modest ratio but a very high probability can still have better expectancy.

Another example shows why stop placement matters more than target dreams. A trader who sets a tiny ten-pip stop to manufacture a great ratio will be stopped out by normal market noise again and again. A realistic stop sits beyond a level that would prove the trade idea wrong, such as a recent swing low or a support zone. Build the ratio from honest stops and targets, then check whether the resulting numbers are achievable on your pair's typical daily movement. Recording both the planned ratio and the realised ratio for every trade exposes habits such as exiting winners early, which is one of the most common profit leaks in retail trading.

Different strategies suit different ratios. Scalpers working with small moves often accept ratios near one to one because their win rates are high and their holding times are short. Swing traders holding positions for days usually need ratios of one to two or better, because their win rates are lower and they endure more overnight uncertainty. Match the ratio to your style, and avoid forcing a scalping strategy to chase swing-trading targets. Professional traders often reject trades below a minimum ratio threshold outright, since taking poor-ratio trades forces them to win far more often just to stay above water.

Put this into practice by recording the planned ratio for every trade before you enter, then comparing it with the actual outcome after exit. Over a month you will see whether your targets are realistic or fantasy, and whether early exits are destroying your ratio. Small improvements — letting winners run a little further, or refusing trades with poor ratios — often lift overall results more than finding a new indicator ever will. Over a large sample of trades, small improvements in your average ratio compound powerfully, which is why ratio discipline deserves as much attention as finding new entry signals.
