Why was yesterdays balance better than todays?
You do not need to bother. This means that the market has reversed against the open position and the trader has left the market with a reasonable loss. This is a normal procedure. Effectively managing risk in a long-term run allows the trader to create trading opportunities. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose.
