All your positions in your image show that they exit within 25 minutes of opening so they must be closed by the trailing stop or the target profit as otherwise they would close on a whole hour and yet the number of bars shows a value of 2? That seems a bit weird to me. Are you definitely running it on a 4 hour chart?

Normally if my systems close out in the same bar that they open in it is a zero bar trade so 2 seems wrong.
