Trading over news announcements are allowed, but it’s important to note that doing this has increased risks due to issues of liquidity around this time. If you set limit orders such as buy stops, sell stops etc. then the order will always be filled at a price being offered by our liquidity providers. This will more than likely lead to extreme levels of slippage on high impact data announcements where prices gap through the requested price and the next available price is x pips away.
