Best fixed spread brokers?

I’ve tried Googling for this topic but most of the websites appear there are affiliate sites so I don’t trust them. Anyone used fixed spread brokers? What is the best one that works for you?

I have a very simple suggestion for you and it’s not to go with fixed spread brokers unless you like news trading. It’s basically because you always need to pay more. I have used Instaforex in past with fixed spread of 3 pips, it was just too much for me, so I switched to Octafx now and there I usually have to pay under 1 pips unless again you are trading on news, so if you are not a news trader than go with flexible spread broker.

Dear Karlsen,
May I ask about Instaforex for news trading? is that good broker? indeed i read many thing negative and positive about them, may I know ask your opinion about them.
million thanks in advance.
