You are right about the chart being misleading. If you want to see the real trading range dont use synthetic spreads on ib and instead check out the es exchange traded spread for sep-dec. Youll see the moves are a lot less dramatic as they appear on the synthetic. Youll most likely never get filled on those movesthat are far from the mean price. And if you do get filed you nost likely will be hung on the opposing leg or get slippage. Its largely arbed out imo.
Thx R87 - it is clear that IB's charts lack some very basic stuff, like the right info - they really should get their stuff in order, but nuff bout them, they are what they are and they never listen to anyone.
I originally thought that futures spread trading might offer some low risk trades, but the more I look into it the less I am thinking that way, as you rightly say, those with access to the "best" systems have the arb opps snapped up in a microsecond, and us plebs are left sitting in the dark, as usual!
I will give it a bit more looking, but on FTSE MIB spreads as opposed to US markets - as I will be doing some MIB options and futures trading shortly - hard to beat the big boys at this game, but very few of them know how to read a chart, which is the only thing us plebs can beat them on - once we learn it the correct way, of course!
