This is an example of a technical analysis strategy that traders use to identify potential trading opportunities. Technical analysis involves studying historical price patterns to identify potential opportunities in the market. In this case, the technical analysis strategy is looking for a breakout or retest of an ascending trend line, which is when the price of a currency pair breaks through or retests a resistance line created by a series of higher highs. This could signal that the trend is about to reverse, providing an opportunity for traders to enter a short position.
