Possibly because the price of silver pulled back under us$18.00. So if some one bought ARDOB options at say $0.005 they would need a price of at least $0.03 cents to buy a share of ARD and only break even. That is if they wanted to do that.
You need to look at the risk/reward and at the moment people don't want to pay more than $0.005 for the OB options.
So for some one to buy the Options they have to see a reasonable return for their money out layed. That is the risk! You have to leave something on the table for the next guy or else you may not be able to sell them at the price you want. He or she has got to think that there is a dollar in it for them to.
Or why bother? Remember options are binary.
So when the Silver price re-gains its composure, I am sure the options will do very well.
I am well aware of the exercise date.
Also remember ARD has finally busted past 2 cents and is starting to get it's mojo back.
Also the ARD share price wont go straight up,
There will be pull backs on the way up.

Cheers
