Yesterday was one of this day that you will remember for a long time.
Whereas Draghi was supposed to release the information about interest rates, the Financial Times has posted too soon (before the official announce) an article about it.
According to them the rate was supposed to be let unchanged. But few minutes later the ECB was saying that it will lower the key rate by 10 points to -0.30%.
The reaction was a hundreds of pips spike on EUR pairs and CHF pairs (repercussion).
The worst pair :
The price has destroyed all possible stop orders, long as short. Only few people who have entered after the first long and short legs have been able to make profits. The other involved have got their accounts wiped out or with a margin call.
That's why it is important to be aware of the fundamentals or just not to trade before news. Especially news related to the QE.
