Option Screener
Here is the stock options screener. If you view source and goto the iframe src there are actually a lot more options and search criteria. I just had to make a slimmed down view to fit reasonably within this blog theme.It uses a lot of ajax calls which make the interface pretty great, but that also makes it pay a search ranking penalty. If you find this useful, do me a favor and give it a link.Some detail: after getting the data, making minor modifications to the structures, then seeing how long some of the results took to load I realized it needed to be faster. For now I have a multi-tiered caching system that will reuse results that are less than something like 3 hours old. Initial loads can still be a little slow, but subsequent loads within the 3 hour ttl are pretty quick. Loading multiple tickers works pretty smoothly until there are over around 5,000 rows of options data. Caching cant fix this. I need to re-assess the data structures, filtering, and sorting. A lot of it is deferred to php code. If I moved all the attributes needed to create the filtered views to a database and did the filtering and sorting in database calls it would most likely improve the performance greatly. I personally think its the best options screener available. But I am still a little fearful to test the waters of options again, feels like playing with fire. You could definitely use it to potentially find low premiums for married-puts, which seems like a pretty boring way to use some great new options analyzer - boring is often good when it comes to investing.tags: options, stock options, puts, calls, screener, intrinsic value, premium, finviz, google finance

I would like to order the option screener but would like to know a little about it first. Can you please tell me what input criteria are available (time to expiration, volume, open interest, stock price limits, etc) and what is the output and can it be ordered in term of yield (say premium over underlying cost for covered calls). Thank you, Scott Sanford snfrd@hotmail.com

I transferred this site to a new server a few months ago and forgot the options data was in it’s own database. I am in the process of transferring the database. I haven’t been making any option trades lately, so wasn’t my highest priority. Will get it running again soon so you can check it out.
lets see.. response to your questions:
-time to expiration – yes
-volume – I don’t remember including that, but could possibly modify it if it’s something you really need.
-open interest – yes
-stock price limits – nope, I do have some underlining stock info, would be open to suggestions.
General response, there are quite a few criteria that the results can be filtered and sorted by.
Suggestions from experience using it: There are obviously higher commissions involved with making complex trades that include options and possibly stock, compared to just stock trades. I feel the smallest order that should be placed for these types of transactions is in the $5000 range. I became by far the biggest fan of using it for married-puts, essentially completely eliminating potential loss, in exchange for expenses that cut into dividend yield. Since dividends are a key factor of a profitability, I would suggest FAR future expiration dates whenever possible (6 months or farther). The orders I placed were definitely on the lower end of value[$5000], and felt were not “aggressively” filled. I never had much luck getting fills with spread orders, but I could almost always get the mid price[half between ask and bid] when I placed the orders separately. I’ve definitely experience different quality of order-filling depending on the broker. Right now I use optionshouse, and have been pretty disappointed with their order filling. However I have a pretty small portfolio, so the ultra low commissions are pretty important to me. I used it fairly regularly for about 6 months. About every 3 months there was a deal that was significantly better than the others [I got a really low premium married-put on nokia while their dividend rate was fairly high]. i.e. I have a feeling 3 months is a reasonable length for selection process.
OK. hope that helps,
should have it up by the end of this weekend.
