I'm pretty new so forgive me if this sounds dumb but...

Z12 is currently shorting USDCAD, I'm wondering whether it's a good idea to stop it and whether stepping in to nip potential bad moves of the Z systems is a good idea in general?

Given the oil stuff going on and the continuous upwards trend of USDCAD, it seems really odd to short it. I have a feeling that Z12 is likely following Z2's mean reversion signals right now (is there a way to check that? What is the "HP" algo code? Are these documented?) but the news around CAD indicates to me that mean reversion isn't likely to happen in the near future.

On the one hand I have a nervous voice in my head telling me Z12 doesn't have all the facts and can make mistakes that I should correct.

On the other hand I feel like this is just nerves and drawdown making me panic and act unreasonably.

What do people think?

EDIT: The Z system docs document that HP does indeed belong to Z2, which means Z12 is currently betting on mean reversion on USDCAD. Maybe a good idea to block USD/CAD:HP?
