Sorry for the delayed update on this PR. I think I have added all the required updates.

The endpoints I can run are only those that are public. The change I made, TimeInForce is mostly used by the authenticated, order-related endpoints.

I am open to hear any other alternative of running the authenticated tests you may suggest
