I hope all understand why is hard to say for us with 100% stop it or not?
1. The Forex news affect the markets every time in a different way so we never know what will be the movement before, during or after the Forex news. So by stopping on those we limit the risk.
2. The EAs are created on historical data including the news, so basically they need to stand on these news and if we go on stoping, managing the trades, we do go back to manual trading.
So these are two major issues or theories that you need to choose one.
Also it depends what kind of Portfolio of EAs you are trading. If you are with trend following strategies and the Forex news go strongly against the trend you will expirience a drawdown in you balance.
