Do you really expect an answer with so little information? Put some effort into explaining your issue in much more detail, including sample code, screenshots, log output, etc.

This is an English forum. We cannot read your screenshot which I assume is in a Chinese dialect.

If you prefer to speak in your native language, you can use the Chinese forum.

Also, you are using MQL5 (not 4) but for some strange reason it is incorrectly branded as MQl4.
