Has anyone used robot on Exness? If I want to...

Yao Liu: Since I don't use robot on Exness so maybe you can provide more information such as the Default parameter of the Time Filter, the time frame used by the robot, etc?
Time Filter can eliminate some of the time whether it is days, hours, minutes, or even seconds so that the robot does not open a position when it is in that time range. There are also those who work the other way around by utilizing the parameter value in the Time Filter to set the time range in which the robot may open a position. Regarding how to customize the robot with the broker's server, that's up to your preference. If you log in to a trading account, Metatrader will be automatically connected to the broker's server. The difference will be in the Latency or Ping of your platform. If we are located in Asia, and the server is in the US, then the latency or ping will be very large and can cause delays in opening positions. To fix this, you can rent a VPS or use a free VPS from the broker. These VPS are located in various parts of the world, So you can choose one that is located close to the server used by the broker.
