I guess you would need to clarify if you are trading a second after the release of the number of it or just using the volatility caused by the number to put trades on since sometimes there is more interest for the following 30 min to few hours after the release then if there was not a number. However not every news release moves the bond market in the "predictable direction" based on the news releases. However that too is information if you are flexible. The move could have been priced in already or even the miss of the economic number could have been priced in too so the market moves opposite of what you think it should. IF you are flexible though you can trade a market that is doing the opposite of what it should. There are usually a lot of people fighting the move at first trying to go the "correct way" of the econ numbers so you can get fast moves as all those traders get stuck. That should tell you where the market is potentially heading and get you on the right side of the market.
