Invalid stop loss

Invalid stop loss or take profit is an error in MT4 that appears when traders set stop loss or take profit values too close to the current market price or in the wrong place. The price distance between stop loss and current price or take profit and recent price needs to be set appropriately. Sometimes traders put stop loss or target values outside the correct parameters range for that particular instrument.

​

​Another reason could be that prices go in price steps of 0.1 while the charts is drawn using 0.01 increments. To check if this is the problem, set the override symb: price step parameter to the value 0.1.
