At the bottom of the Moonbot terminal, the circle changes color from green to orange – is this dangerous?

Circle or “traffic light”, its color indicates the quality of the connection to the exchange, if the light is green, then everything is fine, if the light is orange, then there are problems with the connection or a significant slowdown. In this case, you can try to change the methods of connecting to the exchanger, restart the router or wait for the lags in the exchanger to stop.
