like I mentioned before, I do not remember where i got it from, but I have used it for a "reference" on how to setup plays on News Releases.
It shows the typical reaction of the events with different currency pairs.
Last wednesday I setup the straddle on the GBP/$ for the BOE Meeting Minutes and made about 40 pips. Then repeated on the EUR/$ on the Interest Rate Statement ..another 40 pips.
I made sure to set the straddle a little wider than recommended. I used +/- 15pip on anything that Forex Factory Calendar showed as High Impact.
