I want to ask, I once registered at Instaforex, but at that time I forgot to check the box in the Islamic account (free-swap) section. Can I register again with the same identity and email? Because I once read an article that if the Islamic account is not checked, I am afraid there will be interest.
you are logged in to the insta forex member area. Click Personal Information
then a display will appear 
you click Change swap
However to change it. You must not have any Open trades in your MT4.
Thanks
To Arip Sanjaya,
You do not need to register an account using a new identity (ID card, email, or phone number). You simply need to activate the swap free feature in your trading cabinet. If this feature is not available, you can simply create another trading account that supports the swap free feature.
Hopefully this helps.
