This is a very good question. Applying econmic data to trading is becoming a very difficult game nowadays. In the past it was possible to get an edge by speaking to 'people in the know', information wasnt as widely available as it is now, so you were able to get a marginal edge over the crowd. Sometimes you will find the how the price action is after key data will give you a good feel for how the mkt is positioned and which way it wants to go. Use economic analysis to formulate your macro views to supplement your trading not for reactionary trading. Rememeber trading is about risk management not just direction!
