### What are R and R-Multiples?

R (aka R-value) and R-multiples is a concept developed by Dr. Van K. Tharp, the well-known professional trading coach who wrote several trading books such as “Trade Your Way to Financial Freedom” or “The Definitive Guide to Position Sizing”.

So what are “R” and “R-multiples”?

R or R-value is the initial risk taken in a trade, based on your stop loss.

E.g.: You buy 100 shares of stock XYZ currently trading at $100/shr, for a total of $10,000. You place your stop loss at $90. So your risk is $1,000 if you are stopped out => your R is $1,000.

R-multiples are – like the name implies – multiples of R. In the previous example, if you get stopped out at $90, your R-multiple on that trade is -1R. If you actually exited the trade at $120/shr, your R-multiple on that trade is 2R.

So the R-multiple is the amount profited (or lost) expressed as a multiple of your initial risk.

Any profit or loss can be expressed in R-multiples.

All good. **But what’s the point of using R and R-multiples?**

Glad you asked.

**Why R and R-multiples are useful?**

**1. Thinking in Reward-to-Risk**

Being able to think in reward/risk is really important in trading. Being able to make more on profitable trades than you lose on unprofitable trades is one of the most important ingredients of being profitable over the long term in the markets. And as you can see, reward-to-risk thinking is integrated in the R-multiple concept. When you get -1R trade, you basically cut your losses perfectly and only lost the amount R you defined prior to entering the trade. And when you get a 3R trade, for instance, you know that you made 3 times the amount you risked. So by thinking in R-multiples, you are in the mindset of cutting your losses short and letting your winners run.

**2. Protecting The Downside & Knowing How Much To Bet**

Since the R-value is the initial risk taken in a trade as defined by your initial stop loss, you not only have no choice but to know exactly where you’re getting out before you get in, but you also have to calculate your position sizing based on your R and stop loss.

So there’s a good implied risk management focus when using R & R-multiples

**3. Less Money Pressure, More Process-Focus**

The vast majority of us have a very strong emotional attachment with money since we associate it with survival, safety, status, and power, or basically most of our human needs.

So no wonder trading is difficult since money is on the line all the time, the money we’re risking, or the money we’re not making.

Thinking in R & R-multiple places some kind of a buffer between us and the thought of money.

Instead of risking $1,000, we’re risking 1R.

Instead of losing $500, we’re only down -0.5R.

Instead of thinking you’re already up $500 and not wanting to lose it, you’re only up 0.5R, much less than your initial risk.

Etc.

It also makes it easier to think in a series of trades, instead of one trade.

This series of trades: 2R, -1R, 1R, -1R, -1R, -1R, 3R is easier to go through emotionally than going through $2,000 -$1,000 $1,000 -$1,000 -$1,000 -$1,000 $3,000

**4. Easier to Grow Your Account**

If you think in R and R-multiples and for instance associate an R-value with 1% of your account, there won’t be a difference whether your account is a $10,000 account or a $1M account. 1% is 1% regardless of the size of your account.

**5. Expectancy and Expectations**

With R-multiples, it is really easy to calculate your expectancy, meaning how much you can expect to make (or lose), on average, per trade.

Calculating the expectancy with a series of R-multiples is really simple. It’s the average.

E.g.: Average of (-1R, -1R, -1R, 3R, 2R, -1R, 2R, -1R, 3R) = 0.56R

The expectancy of that series of trades is 0.56R, meaning that you can expect to make 0.56R per trade, on average.

And if you know your trade frequency, you can have a rough estimate of what you can expect to make over a certain period of time.

If let’s say that you have on average 100 trades per year and your trade expectancy is 0.56R per trade, you can have a general idea of how much you can expect to make per year, which in that case would be 56R.

**6. Position Sizing**

Position sizing is probably the least talked about topic, but one of the most important ones as it will determine your max drawdown and risk of ruin. And you guessed it, using R & R-multiples makes it easier to know what kind of position sizing would be appropriate for your needs.

You first need a good sample size of your past trades (let’s say 100 trades) translated into a series of R-multiples. We basically assume that the trade sample is representative enough of your strategy.

You then run randomized shuffling of this R-multiples series, which is called a Monte Carlo simulation. You can randomly shuffle those trades using Excel for instance. There are many youtube tutorials on how to randomize a list of elements.

Let’s say you run 1,000 random shuffles. You can then find out, out of those 1000 shuffles, what the maximum drawdown was, and what the maximum losing streak was.

Based on those, you can then determine what would be a comfortable R-value for you, in order to make it very unlikely for you to lose more than what you’re able to stomach.

Let’s say that the max drawdown out of the 1,000 simulations was -31R, and that you are unwilling to be a drawdown of more than 30%. Well, you now know that you should be risking less than 1% per trade, meaning your R-value per trade should be less than 1%.

There are many other fancy calculations you could extract, such as the percentage of chances of reaching a certain drawdown based on the number of series that reached that drawdown, or percentages of chances of reaching a certain profit. But you get the gist I hope.

R & R-multiples can allow you to optimize your position sizing to your needs, instead of, for instance, using an arbitrary position sizing that could potentially have too high of a chance to lead you to ruin.

**R-Multiple Warning**

It is important that you are aware that the sample of trades you use should not only be representative of your strategy, but it should be representative of your strategy during a certain market environment, as future results can be completely uncorrelated if the market environment changes. For example, different market environments could be high volatility up, high volatility sideways, high volatility down, low volatility up, low volatility sideways, or low volatility down. One should ideally get different samples of trades per different market environments.

**What are the limitations?**

**1. Approximations**

Like any concept in trading, R & R-multiple are not foolproof, nor are they the Holy Grail. They are a useful tool that can give you an approximation of what to expect and a mental edge. There can be a big discrepancy between the results you get and what can expect, especially given the fact that it is possible that we get filled at a much higher (or lower) price than the price we based our position sizing on.

Also when using percentages, one has to be careful not to expect an optimum compounding effect, since it is possible to be in a situation where we don’t have enough cash left.

**2. Several Positions**

That brings me to the second limitation of R and R-multiples which is that assumes one takes one trade at a time and overlooks correlations.

**R-Multiple Calculator**

You can use this position size calculator to easily determine what your r-multiple would be. Just input all of the values including the potential profit-taking price and it will calculate it for you.
