$($a$)$ Explain what Moving Averages are and how they can be used as an analysis tool when studying commodity futures charts.

$($b$)$ Attach one commodity futures chart illustrating a moving average line for any one period of time. For example, you may include a May $2024$ canola futures chart with, for example, a $9-$day, or $18-$day moving average line, or for a greater period of time. Clearly indicate and label the technical analysis formation $($moving average line$)$ on the futures chart you attach. Any commodity futures chart may be used to illustrate the charting formation and any time period for the moving average line may be used. Circle one instance were the price crosses over a moving average line indicating a change in price trend.
