Research the difference between Market Execution and Instant Execution (dealing desk vs ECN).

ECN and Non-Dealing Desk brokers use Market Execution (not Instant Execution), so deviation limits do not apply. Market execution accepts whatever slippage occurs. You cannot limit it via the deviation field that is only available in Instant Execution.

Learn to embrace slippage and how to work with it. You will be better off with it and Market execution than with Instant Execution on Dealing Desk or Market Maker brokers.
