Buying vs selling options are two very different animals. With buying options my risk is limited to the price I paid for the option. There are some limited exceptions to this at expiration. In sharp contrast, with selling options my risk is far greater and undefined unless I do a spread. I am...

I would only consider buying calls in VRX for a daytrade. It's IV is too risky for me.

Here's UAL

Contrast VRX above with buying puts and calls on SPY being mindful of IV:

Check out this VRX for good example of when NOT to buy calls. See how elevated the IV is compared to where it historically resides at about 0.3. If you buy calls now, the IV will eventually revert to a lower level and you will lose big money irregardless of the price action.

It seems what's most important is the value of the delta and vega of the strike you buy for this deep OTM SPY trade. Also relative iv matters. If I look at the option chart and compare it to the stock chart overlayed with the IV I see that this was a bad trade from mid august to the end of...

Many thanks for taking the time to write this up. It is very helpful!

Check out this SPY thread where you can buy very cheap OTM options for a vega play but still benefit when SPY uptrends. http://www.elitetrader.com/et/index.php?threads/thoughts-on-long-otm-spy-calls.295104/ It's best to use stocks with the highest option volume to minimize giving away money on...

"I'm currently looking at OTM SPY 225 calls for Jan 16. Right now these are going for .03 to .04." These calls have done well, not because of any IV change but because of a nice SPY uptrend. The IV has hardly changed.

You may also want to scan for stocks that not only have low IV but are trending or breaking out so you have a better directional bet.

If I can't admit I'm wrong or that I could have done something better, I can't improve. I also can't take small losses before they become large ones. The cultural model is to mercilessly attack and annihilate people who admit they made a mistake, were wrong or changed their mind. Many view...

I didn't even know these existed. Thank you for the link. I am disappointed that they put such wimpy cpus in these NUCs.

"I don't even get why the OP is so cheap. If he is profitable is it really the trading laptop he is trying to save a few bucks???" This is why I started this thread. I want to hear opinions and points of view that challenge my current line of thinking. I make better decisions that way.

I am close to buying a refurbished or used Dell Precision M4600 with 16 GB Ram and 256 GB SSD similar to this but with a 256 GB SSD: I believe this unit is about 4 years old. I am wondering what I can expect for a useful life for this or any laptop. What has your experience been? What...
