I would like to test whether buying a group of ETF pairs and writing calls against them is viable. I would need to test the over-all gain/loss in each pair and while WLP doesn't have options in it, if I could get it to report the percent price change from close-to-close on the third Friday of each even numbered month I could use my brain to figure the rest...

The idea here is to hedge say: SSO against SDS and write calls against them both. Theoretically, I should get a very small decline in capital value over a period of time (each ETF will rise/fall at about the same rate, minus an expense ratio). Then I write the options to cover the decline.

It would also need to rebalance the pairing every 10-20 percent to keep from getting way out of whack...

Any thoughts? Suggestions?

I'm pretty new to WLP, but I have some coding experience...just need to implement it in here...

Thanks for everything
