Question 1

What is a risiko terhadap reward ratio (R:R)?

Accepted Answer

A risiko terhadap reward ratio compares the potential loss of a trading to its potential profit. It is calculated by dividing the distance from your entry to your take-profit (reward) by the distance from your entry to your stop-loss (risk). For example, if you enter at $100 with a stop-loss at $95 (risk = $5) and a take-profit at $115 (reward = $15), your R:R is 3:1. This means for every $1 you risk, you stand to gain $3. Higher R:R ratios mean you need to win fewer tradings to be profitable overall.

Question 2

What is a good R:R ratio for trading?

Accepted Answer

Most professional tradingr aim for a minimum R:R of 2:1, meaning the potential reward is at least twice the potential risk. However, the 'best' R:R depends on your tingkat kemenangan. A scalper with a 70% tingkat kemenangan can be profitable with a 1:1 R:R, while a trend tradingr with a 30% tingkat kemenangan needs at least 3:1 to impas. The key is that your R:R and tingkat kemenangan together produce a positive nilai ekspektasi. Use the required tingkat kemenangan shown in this calculator to determine if your R:R makes sense given your historical tingkat kemenangan.

Question 3

What is nilai ekspektasi and why does it matter?

Accepted Answer

Nilai ekspektasi (EV) represents the average amount you expect to gain or lose per trading over a large number of tradings. It is calculated as: EV = (Tingkat kemenangan x Reward) - (Loss Rate x Risk). A positive EV means your strategy is profitable in the long run, while a negative EV means you will lose money over time regardless of short-term results. For example, with a 2:1 R:R and 45% tingkat kemenangan: EV = (0.45 x $200) - (0.55 x $100) = $90 - $55 = +$35 per trading. This is the single most important metric for determining if a trading strategy is viable.

Question 4

What is the required tingkat kemenangan and how do I use it?

Accepted Answer

The required tingkat kemenangan (also called impas tingkat kemenangan) is the minimum percentage of winning tradings needed to avoid losing money at a given R:R ratio. It is calculated as: Required Tingkat kemenangan = 1 / (1 + R:R). For a 1:1 R:R, you need to win 50% of tradings. For a 2:1 R:R, you need 33.3%. For a 3:1 R:R, you only need 25%. Compare this to your actual historical tingkat kemenangan. If your actual tingkat kemenangan exceeds the required rate, your strategy has a positive nilai ekspektasi and is worth trading. If it does not, you need to either improve your entries or widen your take-profit targets.

Question 5

How does position size affect risk and reward in dollar terms?

Accepted Answer

Position size converts the percentage-based risk and reward into actual dollar amounts. If your R:R is 2:1 with a 2% risk from entry, a $10,000 position means $200 at risk and $400 potential reward. A $50,000 position on the same trading means $1,000 at risk and $2,000 potential reward. The R:R ratio stays the same, but the dollar impact changes. This is why penentuan ukuran posisi is separate from R:R analysis. First determine if the trading has a good R:R, then use a position size calculator to determine how much capital to allocate based on your risk tolerance.

Question 6

Should I always take tradings with the highest R:R?

Accepted Answer

Not necessarily. While higher R:R ratios are generally better, they often come with lower tingkat kemenangans because the take-profit target is farther away and harder to reach. A 10:1 R:R trading that only wins 5% of the time has a negative nilai ekspektasi. The optimal approach is to find tradings where your expected tingkat kemenangan significantly exceeds the required tingkat kemenangan for that R:R. Also consider that very tight stop-losses (which inflate R:R) can cause you to get stopped out by normal market noise. The best tradings balance a reasonable R:R with a realistic probability of reaching the target.
