How do the spoos add major liquidity? The E-minis trade 5 times the value of the Spoos each day...
Quote from FredBloggs:
sp is 5x the value of es.
1 pt in sp = $250
1 pt in es = $50
5x es = 1 sp.
also tick size is larger is es at 4 ticks per pt x 10 ticks per point.
so pit trader hedges 1 sp position with 5 es.
sp moves 2 ticks, es stays at same level, un wind position for 1-2 sp ticks & evens on es.
think thats the idea.
hope that helps.
