Yes, martingale and layering strategies are allowed within a single account.
However, these strategies must not be used across multiple accounts to avoid manipulation or strategy abuse.
Example:
Opening the same pair across multiple accounts is permitted under the following condition:
You may open a Buy position on XAUUSD in Account A and subsequently open another Buy position on XAUUSD in Account B, as long as both positions are opened within 5 minutes of each other.
If the positions are not opened within 5 minutes of each other, then the position in Account B may only be opened after the position in Account A has been fully closed.
Important:
If positions on the same pair are opened across different accounts more than 5 minutes apart, any profit generated from such activity on all accounts involved will not be eligible for payout
This behavior is classified as sequential trading across accounts, which is strictly prohibited.
