where can get free real time greeks on option chain on web?

I didn't realize there were any sites that offered real time options quotes. Thought you had to go through your broker or pay for the service.

Thanks for the post. I wonder how they get around paying fees to the exchanges/opra. A professional could use this site as well and avoid real time pro fees.
 
Can someone explain the following differences in Bid/Ask for Call Strike=1 (0.60/0.65 vs 0.55/0.60) ? :

Here's a suggestion for improvement: it shows only the Last price of the underlying. It better should show also the Bid and Ask of the underlying too, b/c Bid and Ask are needed when filling out an order, for example a CoveredCall order, where the underlying is involved too in the trade. The calculations for NetDebit or NetCredit require also the Bid/Ask of the underlying.

Another improvement would be if it would show also the IV of each strike.

Btw, the chart of the historic prices of a strike is cool & useful, IMO :)
Especially the 5d chart.
Comes after clicking on a strike row.

But... returning from the chart is unfriendly: it does not keep the selected ExpDate; one has to do it again...:(

I do not quite understand why anyone would look at the options for a stock trading under $1, but here are the closing markets from today on Lightspeed Trader.

The question was about the differences in the data, both as of "now", ie. at market close.
And it shall not be your concern when others trade options of such penny stocks.
