Many people will talk about their forex Risk-Reward ratios such as it’s important to have 2:1, 3:1, or whatever to one ratio, but this is just the tip of the iceberg of risk-management and leaves you uninformed and un-empowered.  You can actually have a 3:1 Reward-Risk ratio and lose all the money in your account.  You can also have a 1:1 Reward-Risk ratio and make money day in day out.

How can you understand the difference between the two?  Through the Risk-of-Ruin formula.

We did a 1hr webinar on Risk Management, the Risk of Ruin formulas and how critical they are, whether you are trading Price Action Strategies, Ichimoku Kinko Hyo, or any other system.

I got many requests for the information contained in the Risk of Ruin formulas so I am posting all the tables here so you can see the mathematics of your trading and whether you have the numbers in your favor.  Here they are below:

Hopefully after viewing the Risk of Ruin tables and underlying forex trading risk mathematics, you will begin to look at your trading differently, analyze whether you have the mathematics in your favor to make money day in day out, or are setup to lose money. Understanding the mathematics of risk can make all the difference in the world so make sure you study these numbers in relation to trading your rule-based system.


Trading Foreign Exchange on margin carries a high level of risk, and may not be suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in foreign exchange, you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose.
