I hope those who long after the breakout from the channel had already close their position. At 1500 hours yesterday, it breaks down from the 618 level with a long red candle, signalling no rebound but continued selling. If you had put your SL here, yes , you lose money but lesser, much lesser compared to those who leave it empty and suffered more losses as at current price.
I learnt my lessons well - no matter how confident you think of the trade, ALWAYS , ALWAYS , ALWAYS have a SL. It can be your life saviour in times like this.
