Producer Price Index (PPI) is an important economic news release.
PPI has the potential to move the market big time if there is deviation between the expected and the actual.
Markets work on the principle of expectations.
Before the release of PPI figures, analyst make an estimate of PPI that is expected.
When the actual data is released, if the actual is different than the expected by a large margin, market will adjust itself.
This brings a period of volatility in the market that can make a lot of pips for you.
If the actual and the expected are roughly the same, there will be little reaction.
