lowest spread (bid-ask) for silver/usd

[rebate trader]

which company provides lowest spread+commission for trading silver/usd
until now i find some companies like Lmax but i would be interested to find some more. Of course CME offers also good spreads for their silver futures but i need different/smaller contract sizes. I am also aware of the SLV ETF but thats also not interesting for my strategy. Thanks!

Smallest bid ask[not on a percentage ] is cash markets. I use derivative charts[printed] for my silver prices, not exact but close enough....................................................................................................I see this week $17.76 holds, not in silver, but in American History,war won,LOL
