1 blockchain = 1 ticker, not 2
Let me help you with that. Elementary topology:

G======

Initially one chain. Then split. Now two chains. Both trace back to the satoshi genesis block. 2009 Jan 03. Both.
Right I understand that BCH forked from BTC, that's pretty obvious, thanks for your unnecessary condescension, but it has its own blockchain and its own ticker. If its blockchain was the same as bitcoin, then why can't you spend bitcoin on it and vice versa?
There is bitcoin and then there is an altcoin pretending to be bitcoin which is constantly falling in price relative to bitcoin.

You're welcome.
