There may be a number of reasons why you are unable to enter your order into MT4:
- You may not have sufficient margin in your account to cover the position you are trying to open.
- The market price may have changed since you placed the order. If you have set a maximum deviation, it may be that the difference in the prices is greater than the pip range you specified. This will result in a requote.
- Your stop-loss and take-profit levels may have been set too close to the market price.
- Your pending order is incorrectly placed above or below the current market price.
