a question on taxation if I live in a state other than where my

This is a question from a net-friend
==========================================================
I have a house in OH and have no intent to sell it.

Right now, I have been working and living in a different state and for a different company for 8 months. I rent an apartment here, the state has no state TAX.

Question: Do I have to pay OH TAX for my income from investment?

If it is yes, is it all trades or is it up to the days I sold those stocks?

I just noticed I am still paying OH TAX
