Hey Bruce,

I have a Weekly SPY chart with a Rate of Change % plot.

Now that SPY has weekly options that expire on Wednesdays, I'm also interested in the week-to-week change in the SPY (based on Wednesday closes).

Doable?

Not really. You could do a 5 day percent change on or after market close on Wednesday, but this would only be accurate going back to the first market holiday in the past. After Labor Day and moving backward it would measure Monday to Monday until the next market holiday.

Thanks StockGuy!

I suppose I can always export the 500 bars of daily data and calculate the Wednesday to Wednesday percent change in Excel. That'll give me almost two years to work with. Should be enough for my needs.

Thanks again.
