Hi Mustafa,
The Maximum Equity Protection was hit at $50195.48, so the open trade is closed and the EA/robot is removed. This is done to keep the robot from turning downward causing your account to start losing money. This is a handy feature when using in an FTMO Challenge. To pass the challenge your FTMO account has to gain 10%. So it your account reaches 10% profit it will close the open trade and remove the robot to complete the challenge.
Alan,
