Trailing stop
A dynamic stop that follows price at a set distance as it moves in your favor and stays fixed when it moves against you.
There are types with a fixed pip distance, ATR-based ones, and ones that follow structure (moved behind each new low or high). In trend trades it protects profit while letting you benefit from the move continuing.
A trailing stop that's too tight leads to early exits, and one that's too wide gives profit back. Check whether it runs server-side on the platform or only while the terminal is open.
