    Risk of Ruin Calculator

    The cTrader Risk of Ruin (ROR) Calculator is an advanced tool to evaluate your probability of loss when trading manually or by using an automated trading system, it will calculate the probability to hit a specific drawdown or ruin.



    Risk of Ruin vs Drawdown Risk?

    When you calculate the risk-of-ruin (ROR) you define the probability of your loss from your original account balance, so for example, if you started trading with £1000, if your risk of ruin was 20% then you have a chance of losing 20$ of your balance or £200, but as your equity gets larger due to winning trades your ROR decreases.

    When you calculate your risk-of-drawdown (ROD) the drawdown will be the same through the lifetime of your account because the ROD will only get bigger if the losses in your account are lower than the previous highest drop. So, the difference between the account equity and balance is lower than at any other time, the is the highest drawdown amount.


    How To Use The Calculator?

    The following settings are explained below:

    • Win rate (%) – how many of your trades end up in profit as a percentage.
    • Average profit/loss - average winning vs losing trades as a ratio.
    • Risk per trade (%) – The risk taken for each trade as a percentage.
    • Number of trades – the number of trades, the higher the number of trades, the higher the chance for drawdown and ruin.
    • Max drawdown - the maximum drawdown as a percentage you are willing to take.


    How to Read The Results

    A win rate of 50% and an average profit loss of 1 against a risk per trade of 2% when 100 trades have been placed with a max drawdown of 30% would show a probability risk for the peak-to-valley drawdown of 13.8% and total risk-of-ruin to blow your account to be 8.1%
