Trend line has been drawn on a confirmed downtrend that has 12 or more bars moving in the direction of the trend. Trend line has been drawn from the all time high in March of 2021 (highest high) to the current week 24th Oct 2021. Trend line is valid because it has been drawn within 2% of at least 3 peaks. A buy condition would trigger on 2 consecutive weekly closes above the trend line then buying on open the following week.
