Unclear equity curve

I am pretty new around here and don’t know the answer to this. My system, Long-Short ETFs/ETNs, has had not one, but two green equity curves on the chart since about mid October. Why is this occurring?



Min and max equity during the day.

Thanks, Kevin. That makes sense, but…I don’t see it on any other systems’ equity curves. Only mine. And I see it even when I am logged out. ???[LINKSYSTEM_51648869]

It only shows up on the Detail System page. Every system has it, but on some the lines might be very close together.
