Strategy test bugging out

 

Not sure if this is just for me or others have experienced this but, I'm on MT5 and I'm getting jitters on the strategy tester.

I have it set to evaluate each tick and everything is fine until I believe about 2015 December on EURUSD. It will start bugging out and just buying and selling trades immediately. Basically bringing me down to 0 very rapidly. I looked at the chart and it isn't hitting any of my script criteria for opening a trade. Also I noticed there is the buy and ask bar then there is a 3rd green line, not sure what it is. Those 3 bars will start jumping around between a 2000 point range. I believe this it he problem.

I'm completely confused and it is really ruining my script results.

Doesn't anyone have any insight, a fix, or maybe is having the same problem and would like to share their experience.
