btct.co options

[Birdy]

I don't really understand the option trading in btct.co, is here anybody that has some trading experience and can explain me those?

I get that call is a promise to sell shares and put a promise to buy some.
But what exactly are premium and strike?

Click the help tab halfway down the page. It explains options there.

Premium is what you pay on top of the strike price. Strike is the agreed-upon price where you can CALL (force the other party to sell to you) or PUT (force the other party to buy from you) the underlying asset.

So, for example:

Code:

Ticker	        Type	Expires	        ฿ Strike	Quantity	฿ Premium	฿ Total/Share
ASICMINER-PT	CALL	1 d, 0 h, 13 m	1.6	        1	        1.68	        3.28

You can purchase the right to CALL 1 share of ASICMINER-PT at ฿1.6, but you will pay a premium of ฿1.68, for a total of ฿3.28 (if you exercise the option).

As ASICMINER-PT is currently trading around ฿2.4, it would have to gain SIGNIFICANTLY for you to want to call your option. As in, above ฿3.28 in the next 24 hours or so.

If you believe it will, in fact, gain 36% in the next day, you should buy the option. Stranger things have happened.

For security, you likely have to put up the whole 3.28 - I don't know as I don't do BTC options, but it makes sense from an exchange point of view. If you don't exercise the option, the strike would likely be returned to you.

Okey, I think I understand the call option now, but I'm still a bit confused about the Put option.

PUT #352    0 d, 23 h, 29 m    Cost: 0.02525000    1    Strike: 0.02000000    Premium: 0.00525000

This is an option to sell shares, right?
Why does it combine the costs?
I get that I have to pay a premium for the option, but then I would sell not buy a share?
