GBP JPY - Short Observed on Weekly Time Frame

The weekly chart for GBP JPY is telling a story. It starts with showing a broken trendline. As you can see on my chart, the trendline is broken to the downside and then retested (also retesting a major level of resistance). At this meeting point, a weekly pinbar is formed (highlighted in green). Price shows us a rejection as its reaction. There are only 3 main objectives from this point:
1. Set a stop loss
2. Set a target
3. Let price do its thing
