I think that it is better to have the VPS with the same broker as it happened to me that I took a vps and run a signal .... and there was some trades closed (That I didn't closed). when I tried to understand I contacted my broker.... the broker said that the trades are closed in the third party and they are not responsible. when I contacted the third party VPS they said that it is not them, it is my broker !
To be continued ....
