I was reading on FF that if you trade the news alone brokers get sick of it because they are loosing and freeze your account, is this true? 
Negative batman
A true broker gets paid by spreads so by you trading news alone you are trade with generally the highest spreads possible. So instead they would love you for it. Its people like me they dont like because I try to trade when spreads are low and hold on to them for days. This does not make the broker as much money.
If you are with a MM or DD broker you might will receive wide spreads and delayed executions during certain events, sometimes you’ll receive requotes, even login fails.
Tha is why i am not working with DD or MM brokers anymore and that is why i don’t trade the news.
Do spreads widen on demo too? i’m with alpari and i just placed an order with a spread of 2 pips with news coming up at 10
Of course he will never ban you instead he will love you for it like bobmaninc said.
It is completely wrong. There are number of traders trading news only and their account is not freeze so far.
