Hi , I'm fairly new to this market.. Any opinions or comments is appreciated.. Even if you can direct me in the direction of how to find these answers will help.. Thanks in advance! 1. anyone ever trade gold ZG against silver ZI or vice versa.. does it have a close hedge ratio, which is? (for every Buy ZG you have to sell so many ZI) 2. would you say that ZG and ZI move tick for tick.. 3. does silver futures move tick for tick with the ETF SLV?
