This is a different view od the games played in the silver options world.

"Some methods:

• How I.B firms would use a thinly traded floor to print the price that would trigger a massive stop loss in the OTC markets and bury their own clients. Or how they would buy for their own accounts in front of resting limit orders for clients and simply use their clients to stop themselves out if the market printed thru their buy levels. Or how they would use dual representation to show loudly they were buyers on one side of the ring, while they were selling quietly upstairs to other OTC dealers. Trading with themselves in multiple entities, etc."

It is worth reading the entire article even if it wanders a bit:
