There are only two main differences between the CEA and NCA accounts.
Consistency Enabled Accounts (CEA):
– The number of trades you take and lot sizes have to be consistent on a weekly basis.
– You can be paid every 2 weeks (bi-weekly).
No Consistency Accounts (NCA):
– No restrictions on the number of trades and lot sizes.
– You can be paid every 4 weeks (NOT monthly).
If you’re not sure whether you’re going to be consistent, then I would highly recommend starting with the NCA account. You can always switch later on at no charge.
