### Risk of Peak-to-Valley Drawdown

Risk of Peak to Valley drawdown is the largest **cumulative percentage decline** in portfolio value from a previous equity high.

Remember that it is the largest cumulative percentage drop and not one drop of 20% or any other percentage.

It is defined as the **percentage** decline from the trading account’s highest value (peak) to the lowest value (valley) **after the peak**.

If you put **Max drawdown** to 20% in the risk of ruin calculator field and you get the peak to valley results 20% this could mean that your trading strategy is showing a 20% probability of reaching 20% drawdown from an equity high to a subsequent equity low.

This helps you see how quick decline could be. If you lower max drawdown to 10% this would be better because you have 20% to get back to 10% loss from your equity peak.

### Risk of Ruin

The risk of ruin percentage results show the result of our trading strategy, in this case 10%. This means that our trading strategy is showing a 10% probability of reaching 20% drawdown of the starting equity amount.

If your risk of ruin percentage is higher that means you have more chances reaching drawdown on your trading account. Higher risk of ruin percentage is not a good result so try to lower the value of risk to ruin result.
