Inner, Outer & Long term Trend-lines. The break:

​

Once the inner trend-line has been broken and you are on the short side of that specific currency pair you must take profit near to the outer trend-line. In effect, the trend-lines are jut slanted areas of support/resistance so profit taking should be set around these key levels. Not only that, the future price action must be anticipated as the price could be lining up for a third bounce on the outer/long term trend-line in order to perform the next leg (Bullish in this case).
