SI (Silver Futures)
COMEX silver futures, ticker SI. 5,000 ounces per contract with $25 per half-cent tick. Notoriously fast and unforgiving; the micro SIL is the sane entry point.
In plain English
SI moves in half-cent ticks worth $25, the largest tick value most prop traders will ever touch. Silver amplifies gold's moves with less liquidity, producing slippage and air pockets that make tight stops unreliable.
Most prop risk setups cannot absorb full-size SI variance; a 20 cent adverse move is $1,000. Traders wanting silver exposure on funded accounts overwhelmingly use micro silver or trade gold instead.
- A 15 cent silver move on 1 SI is 30 ticks x $25 = $750, from a move that takes seconds on a data release.
