When should I roll my options to a lower strike price?

I am currently holding some PK call options with a strike price of $20 expiring on January 15 2021 and my average cost is $0.3 per contract. I now believe my contracts may expire worthless at expiration and want to move my contracts to a lower strike price ($15). However, liquidity is currently ass and the spread is wide for my current contract. So I was wondering if there's any strategy that can allow me to lower my strike price without loosing too much on the current spread.

Thanks!

 

Where does the 15-20 1x2 trade??
(Probably a debit)
Quote it as a spread

 

why 1x2? just buy the 15-20 call spread 1x1

 

January 2020 is already behind us.

 

Sorry, I meant 2021, edited.

 

What do you mean by 1x2?

 

You have no choice but to keep it until expiration and then do a roll over. This is the most efficient way. You can't outwit the system by doing early roll over and you will just continue to lose more money.

 

Not true...

Are you saying IF he could do the,10-15 or the 15-20 1x2 for even,you would pass on it?

I know it's not there,but at a certain price,you take the shot

 

Of what expiration?

 

Jan 2021..its a hypothetical question..similar to what happened in the TSLA thread..
