One of the most important lessons in trading is that you do not have to risk a lot to make a lot.In fact, the better trading opportunities often come when traders can define their risk against a nearby technical level. If that level holds, the price has room to move in the anticipated direction. If it breaks, the trader can get out with a relatively small loss.That is the idea behind risking a little to make more than a little.Technical levels help define riskTechnical tools such as moving averages, Fibonacci retracements, swing highs, swing lows and trendlines identify areas where buyers or sellers should enter the market.For example, assume a currency pair is trending higher and correcting toward its rising 100-hour moving average. If buyers are going to remain in control, that moving average should attract buying interest.A trader could buy near the moving average and use a break below it as the signal that the trade idea is not working.The moving average does not guarantee that the price will bounce. Nothing in trading is guaranteed. What it does provide is a logical level against which risk can be measured and limited.Know where you are wrongBefore entering a trade, a trader should be able to answer a simple question:At what price would my trading idea be wrong?If the answer is clear and relatively close to the entry price, the risk may be manageable. If there is no nearby level that would prove the idea wrong, the trade may require too much risk.The goal is not to avoid losses. Losses are part of trading. The goal is to keep those losses controlled while leaving room for winning trades to develop.That is why technical levels are so valuable. They give traders a reason to enter, but just as importantly, they provide a reason to exit.The reward should be larger than the riskSuppose a trader buys against technical support and risks 20 pips. If the next meaningful target is 60 pips higher, the potential reward is three times the risk.That does not mean the trade will automatically make 60 pips. It simply means the trade offers a favorable risk-to-reward opportunity.A trader does not have to be right on every trade when the average winning trade is larger than the average losing trade. Conversely, even a trader with a high win percentage can struggle if losses are consistently larger than gains.The mathematics matter.Let the technical level do its jobOnce the trade is entered, the technical level should remain the guide.If the level holds and the price begins moving in the intended direction, the trader can look toward the next technical target. As the price moves, the stop may eventually be adjusted to reduce risk or protect a profit.If the level breaks, however, the trader should respect that signal. Hoping that the market comes back can turn a small, manageable loss into a much larger one.Buyers had their shot—or sellers had their shot—and they failed. That failure is information.Avoid risking too much simply to stay in the tradeA common mistake is placing a stop so far away that the trade is given nearly unlimited room. Traders sometimes believe a wider stop makes them less likely to be stopped out.That may be true, but it also increases the amount at risk.Another mistake is moving the stop farther away after the market moves against the position. That changes the original trade and allows emotion to replace discipline.The better approach is to determine the entry, stop level and potential target before entering. The size of the position can then be adjusted so that a stop-out results in an acceptable loss.The bottom lineSuccessful trading is not about finding a trade that cannot lose. It is about finding opportunities where the potential loss is clearly defined and relatively small compared with the potential gain.Trade against technical levels. Know where the trade is wrong. Keep the risk controlled and give the price room to move toward the next target.That is how traders put themselves in a position to risk a little in hopes of making more than a little.An example. The GBPUSD bounces off a swing area low. The GBPUSD has remained under pressure, with the price holding below its falling 100-hour moving average over the last two trading days. The pair has also stayed below the 50% midpoint of the recent trading range at 1.34067.Those technical signals keep the sellers more in control.However, the price has also found repeated support within a swing area between 1.3321 and 1.3343. On Thursday and Friday of last week, the GBPUSD traded into that area and bounced. In trading today, the price moved back into the zone and reached its lowest level since July 29, but buyers once again appeared near the bottom of the swing area.There is reluctance to move higher, but there is also some reluctance to move lower. That creates a potential opportunity for traders willing to buy against the 1.3321 support level.Defining the riskA buyer entering near 1.3321 could place a stop approximately 10 to 15 pips below that level. If the price breaks below the swing-area low and stays below it, the trading idea is wrong and the trader gets out with a relatively small loss.There are no guarantees that support will hold. However, the level gives traders something concrete against which they can define and limit their risk.That is the first part of the lesson: Know where you are wrong before entering the trade.Identifying the upside targetsIf support continues to hold, the first objective would be a move above the top of the swing area at 1.3343. That would be a small victory for buyers, but it would not yet shift the broader technical bias.The more important upside test would be the falling 100-hour moving average at 1.3371. Getting above that level—and staying above it—would weaken the sellers’ control and give buyers more confidence.Above the 100-hour moving average, the next targets would be:1.34067: The 50% retracement1.3432 area: The 200-hour moving average and 100-day moving averageThat creates a potential path of 60 to 70 pips toward the midpoint level, compared with approximately 10 to 15 pips of defined downside risk.Risk is known; reward is notThe risk can be estimated before the trade is entered. In this example, it is approximately 10 to 15 pips below the 1.3321 support level.The profit is unknown. The GBPUSD may bounce only modestly, stall at the top of the swing area or fail at the falling 100-hour moving average. However, if the price can get above those barriers, a move toward the 50% retracement at 1.34067 would not be out of the question.The trade therefore offers a potentially favorable risk-to-reward opportunity, even though the sellers remain more in control.That distinction is important. Buying near support does not automatically make the technical bias bullish. It simply gives buyers a low-risk level against which they can take a shot. If support breaks, get out. If it holds and the upside targets begin to fall, allow the trade an opportunity to develop.Risk a little in hopes of making more than a little. That is one of the goals of successful trading.
