I use a VPN....gives me better connections..using NT8..my regular fios service is 355MBPs download and 125 MBPs upload...but it drops connections all the time......going to fast I would say.....the VPN thru Avast 56 download and 26 upload....but no lost connections and plenty of speed.......

I have Nord but the higher ping times mess with full MBO level 2 market data and make it not worth it for me to use while trading since I rely on order flow. Whenever I’m not trading I use a VPN to stop my ISP from spying on DNS leaks though

I use Nord VPN for normal browsing but would not use it for trading. It's just one extra cog that can go wrong at the wrong moment. Imagine dropping a connection when you're trading a surprise news announcement?
In my experience (with Nord VPN at least) they are not viable for the exacting connection requirements that day trading needs. The first poster seems to have answered differently although it's not easy to say whether his VPN set up is so reliable because the VPN provider is a lot more stable or whether it's because of all his servers etc make it so.

P.s. I have a hard wired Internet connection. See my point r.e. one more cog going wrong and apply that to a wireless Internet connection
