You have explained very well in this post about stock to flow model which is used for metals such as gold and silver. What is the current number or what is the next number or if we talk about it, we can recognize it from its color, we can recognize it from its colors, where its price will go now, it will go up, it will go down if we talk about it. So really the points were explained to us in a great way and it was really necessary to understand these points. Disadvantages are that people can directly find out which side it is going now and advantages are that people get profit here. Well done and I wish you success in the competition.
