If you stay for the FOMC announcement 6 hours back, you would have see the long spikes in the price charts. After FED announce that they will slow the pace of treasuries purchases at 2.15pm ET, offering some positive news for USD, the USD rose against major rivals (GBP, EUR, AUD & JPY).
If you look back at the charts at the GMT18:00 (which is 2am this morning, SIN/MY time), the candles are almost 100-pips (for USD/JPY and AUD/USD), 110-pips (for EUR/USD) and 125-pips (for GBP/USD) and in an hourly candle. Even GBP/JPY is also greatly affected with a price volatility of 220-pips in that one hour.
WHAT TO TAKE NOTE:
Similar with all major economic releases, there is always significant price volatility with this FOMC announcement. Currency spreads will typically widen just before the release and will remain wide for a couple minutes after.
The spreads widen signficantly and if you are trading with a pending order, do not anticipate being filled at your entry price. You will be filled at the prevailing market price after the release, which could be significantly different from your desired price of your entry order.
