Alpaca data is fully wrong

The ticker prices seem wrong, eg. koss is 1.70 on yahoo finance, on alpaca is stuck at 1.80

True!

Happens much to frequently

Could you provide timestamp of the data issue as well? it’s hard to understand the issue without it.

Yes for sure l,

Thanks for looking into it.

Here is screenshots attached of two different data at the same time.

I too have noticed it’s wrong a lot. Makes it very difficult to trouble shoot or know how well an algorithm is working.
