Hey Simon,
yes, this might happen very often when you trade while news.
You know what? When we generate strategies with EA Studio or FSB Pro we actually use the complete Historical data we god. It includes the news, right? This means that the generator finds SL that work while news. These news happened many times during the data. And when you trade in the future, the news will happen again (of course they are not the same, but they are similar, their effect on the price is similar). So we should expect to get well over the news, even there will be times when the SL is hit.
