I was always watching Silver-Cash and thought was the only graph available. then I discovered the other two. How does it work? Is it a forecast? or what? I noticed that graph is the same but price is increased respectively on the September one and the December one.
silver cash - it is spot price, like forex. silver sept - it is futures sept 20 contract. this contract is actively traded. sliver dec - it is futures dec 20 contract. usually it is priced higher than nearer month (say sept 20) contract. as of now, this contract is not actively traded
