Add symbol "SIC" 100 oz silver futures contract

With the recent spikes in volatility silver micros behave more like and NQ E-Mini.

A new future contract was just released by the CME group

, symbol SIC, called silver 100 ounce futures contract. with each 0.01 cent change in price would translate to a 1 dollar loss or gain making it behave more like a gold micro. I believe this would help both live traders and sim traders manage risk a better because silver micros expose the trader to a 10 dollar loss or gain for every 0.01 cent movement, which is also the smallest position size we can use to trade silver right now. SIC would help us scale into or out of positions with greater efficiency as well.
