Exness is an average broker, they are not excellent but at the same time they are not bad. I have trading accounts with three brokers: Exness, Trade Nation and Pepperstone; out of these brokers Exness is the one I use for day-to-day trading but when I want to trade news events, I use Trade Nation or Pepperstone because they have guaranteed stop loss and they dont really widen their spreads during news events.
