You can change from a standard CFD account to a limited risk account. Simply log in to My IG and click on the ‘settings’ tab. Choose ‘account type’ from the list on the left of the page, and follow the instructions to convert to a limited risk account.
A limited risk account ensures that all the positions you open will not allow you to lose more than the initial deposit required to open the trade. It will ensure that all your positions either have a guaranteed stop, or are on inherently limited-risk markets such as digital 100s. You will not be able to use other types of stops, like trailing stops.
