Making 100 pips from a positive or negative news is very much possible. However, once the trade moves in our favor, it is better to use a trailing stop loss. Needless to say that such a stop loss should be little far from the usual scenario. This is because volatility would be rather high before and after news. Additionally, it is better to spread the risk by taking position in two counters. This would enables us to achieve 100 pips rather quickly. If the currencies are correlated then it will be even easy to manage the two positions simultaneously. Again, it all boils down to money and risk management. A trader who can manage those two criteria effectively will have no problem in making money consistently from forex trading.
