Hi,
The strategy that you found is a simple collar or sometimes called straddle, where you place to orders - one to buy and one to sell and wait for the price to breakout triggering one of your orders.
False breakouts often occur, especially when the release came close to market expectations and traders fade the breakout (i.e place trades in the direction opposite to the initial price movement). Although the stategy relies on "true" breakouts it can still work during a false breakout if you take the profits quickly and don't get greedy plus you put very tight stops to minimize the risk.
