What happened
On 6 September 2011 the Swiss National Bank announced it would defend a minimum of 1.20 francs per euro "with the utmost determination".
USD/CHF jumped about 9% within the session: a central bank can reverse any trend in a single statement.
How to survive a day like this
- Check the economic calendar and the news before you trade: these days were announced or brewing for hours.
- Reduce your risk: on extreme days, 0.5% per trade is plenty, because stops can slip far beyond where you placed them.
- Do not fight the first move. The first candles of a shock set the direction for the rest of the session more often than not.
