One of the real secrets of trading success is to think in terms of risk-to-reward ratios every time you take a trade. A trading system can be characterized as a distribution of the R-multiples it generates. Expectancy is simply the mean, or average, R-multiple generated. A Brief Overview of Risk and R-Multiples.

If you've read any of Dr. Tharp's books, you know by now that it is much more efficient to think of the profits and losses of your trades as a ratio of the initial risk taken R.

Is the potential reward worth the potential risk? So how do you determine the potential risk on a trade? That exit point is the risk you have in the trade, or your expected loss.

The risk you have in a trade is called R. That should be easy to remember because R is short for risk. Remember to think in terms of risk-to-reward ratios.

The same thing works for losses. Perhaps the market gapped down against you. Losses bigger than 1R happen all the time. Your goal as a trader or as an investor is to keep your losses at 1R or less.

But that's not particularly helpful advice for those who are trying to create a meaningful risk framework for their trading. After all, even Warren Buffet experiences losses.

A much better version of his rule would be, "keep your losses to 1R or less. When you have a series of profits and losses expressed as risk-reward ratios, what you really have is what Van calls an R-multiple distribution. Consequently, any trading system can be characterized as an R-multiple distribution.

So what does all of this have to do with expectancy? Expectancy gives you the average R-value that you can expect from a system over many trades. Put another way, expectancy tells you how much you can expect to make on the average, per dollar risked, over a number of trades. So when you have a distribution of trades to analyze, you can look at the profit or loss generated by each trade in terms of R how much was profit and loss based on your initial risk and determine whether the system is a profitable system.

So in the real world of investing or trading, expectancy tells you the net profit or loss you can expect over a large number of single-unit trades. If the total amount of money lost is greater than the total amount of money gained, you are a net loser and have a negative expectancy.

If the total are centrica shares worth buying of money gained is indikator forex paling akurat 2014 than the total amount of money lost, you are a net winner and have a positive expectancy.
