Price Error Causing Day Change Abnormally

I found price error of one US stock in my portfolio - USX:PAWZ - ProShares Pet Care ETF
The price dropped to zero.
It happend a few times and my day change report showed a major lost.


Apologies for the issue.

It is caused by an upstream problem. They sometimes post a 0 close for a short period before rectifying it.

Let me do something on my end to prevent any close to be 0 for US market.


Done. I have implemented some prevention on my side.

  1. Regularly check for price == 0 and alert me so that I can alert upstream.

  2. Do not use close if it is 0, use low instead.

Let me know if it is still an issue. Thanks.
