Yesterday my stop loss got triggered during news release when it was 20 pips away. I knew that this could be caused by the spread so I waited for the website to update its website and only saw a maximum 15 pips spread at that time. I emailed oanda about this and they replied a couple hours later and said that the maximum spread reached 20 pips. So I looked at the website again and found out that it changed from 15 pips to 20 pips maximum spread. I really think that Oanda is not showing transparency as they are claiming it.
