You can use a custom proxy and a proxy from CScalp team in the terminal. Custom proxy - any proxy server that the trader has found and uses for free or paid.
CScalp's built-in proxy servers are located in Khabarovsk and Tokyo. The speed of the servers depends on the location of the trader. Someone would be more comfortable with a Khabarovsk server, someone with a Tokyo server, a trader can use the terminal without a proxy server.
