straddle stock commodities announcement

Hi, A technique used in forex trading is to Straddle a Interest rate or non farm payroll announcement.This consists of placing entry buy and sell 10 or so points above and below the market price seconds before the announcement.

I was wondering is there a technique for commodities such as grain copper silver do they have announcements.?

Is there a technique for stock announcements as well ?

Please PM me if you consider this techniqe to secret to put public on the web ill trade my secrets of course.

The grains have a report from Dept of Agriculture - not sure when (see the movie "Trading Places" with Eddie Murphy!). Don't know of any for copper or silver, but bonds, interest rates probably affect silver along with gold. There is a crude oil report every Wednesday and Nat gas every Thur. Crude definitely reacts. You could maybe place straddle trades if your broker allows it (I don't know about such), but another way to do it is with a put/call option spread. For stocks the magic day is earnings announcements and put/call spreads are popular.
ps: Let's spread all the secrets! ;=)

haha thats where i got the idea from trading places , as i was thinking when i watched the movie a straddle would be a good strategy instead of their inside scheme
