MyFxbook, Entry Accuracy, and Exit Accuracy

Can someone explain how calculates the entry and exit accuracy numbers? What I am seeing in myfxbook for my account is that my entry accuracy is better than my exit accuracy. My entry accuracy is 79 and my exit is 23. This is only over a very small number of trades though. I just started using myfxbook so I think it only picked up those trades since I started. I think it means I do a bad job of managing my trade once I am in it and that I am giving up pips. Maybe also that I don’t have a clear exit strategy.
