Greetings @shanza1
You did a great job explaining the stock-to-flow model for metals like gold and silver. Like you have said, if we understand the numbers and colors, then we can predict if the price will go up or down. It's important to grasp these points. The model is based on calculating the rate of scarcity of an asset and with scarcity come increase in value. Well done, and good luck in the competition.
