Due to SNB decision to stop supporting 1.20 level anymore.
Big movement of 1000-2500 pips also on USDCHF, EURCHF, CHFJPY, CADCHF, etc...
A lot of accounts have crashed, some brokers have a big hole in their finance like IG with £30 million.
And some brokers are asking to their clients to pay their negative balance, like Saxobank.
A real nightmare this day.
