Broker with the most reliable Price/Datafeed

The reason for this thread is the following.
Iam part of a group actually running an EA on different live and demo accounts. The point is that the EA is performing so different along all accounts and brokers in terms of opening positions. For exmaple, even if I compare the trades on my live and demo accounts Arcturus same broker, on demo the EA opens round about 50% more trades than on my live account.

It‘s pretty much the same when we compare all live accounts against each other. One guy had yesterday around 60 scalp trades while others had zero andothers only about 10-12 trades. Today again, I had 3 trades while others had only 2 or none.

While every broker has his own liquidy providers where they get their price & data feeds, the question for me is: is their any retail broker with the most reliable data-/price-/liquity feed out there?

I use different brokers, both live and demo. I often have the same trades with the same EA at different brokers, but not always. However, sometimes there are significant differences or trades aren't opened (everything runs on one computer and one internet connection).
It could be due to different trading hours, spreads, and internet connections. Check the logs!
I have a broker who often doesn't trade/open trades: "No connection." The others don't have any problems at the same time. This is the reason why I use multiple brokers. It's better to use a VPS. Ideally, one with the shortest possible connection to the broker.
