Here are some examples of Currency Trading Insurances:

1. Use a stop Loss
2. Only trading a small set % or your account 1%, 2%, 3%, 5% on any one trade
3. Only trading a total amount of your account at any one time. 5%, 10% … your choice
4. Keeping the Margin level % above 1000%
    (you chose the level of coverage you want)
5. If your Margin Level % drops down to 500% close all of your open trades.
6. Take the total amount you have for trading and put ½ in a savings account
 then put the other ½ in you trading account.  This way you will have some
 money to trade with if you lose you trading account.
7. Never add money to your account to cover a margin call.
8. If your account has a draw down of 10% you stop trading until you figure out
 what you are doing wrong, or what you have changed from when you were making money.
