Trailing stop not working

I had a stop fail earlier today on GPS. Now, on LOW.

I have a 10% trailing stop on LOW. Near the market open today, hwm was 157.3713 and stop_price was 152.650161. Around 9:42 LOW crossed below the stop price and hit a low of around 151.40 before moving back up (luckily).

This is all in my live account. Seems buggy to me, and not in my code. Orders have all been submitted okay.
