Cutz,I don't know how you are managing to trade spreads with IB.I guess the answer possibly lies in Sharkmans reply.
My experience is firstly trying to do it,and secondly long discussions with them as why I could not.I cannot even do it in my paper trading account.They won't accept xx.01 spread trades on the asx,because although they acknowledge them as European options they are not cash settled.The only thing they will allow me to trade is long option positions and limited spreads on European cash settled indices.So if there is anyone else out there contemplating signing up with IB as an individual trader,be forwarned.What annoys me is that I had a discussion with their Australian rep before signing up,and none of this was mentioned,even though I made clear my trading intentions.
Cutz,I am well aware that you can phone commsec for a spread trade and pay a much higher brokerage.A number of times I have waited on the end of the line("sorry for the delay,we will..blah blah....') only to watch a trade move against me.
Trying to leg into the short the short side of a spread with Commsec when it is advantageous is a hit and miss thing,I have found.
Even though the amount in my account covers it many times over,they don't always allow it.When queried about it they usually just play dumb.
Last year they promised a spread trading platform early in this new year.It's never happened.Maybe all the good Australian programmers left to work on the "Think or Swim" platform and never returned.
OptionsXepress seem to offer trading on the US markets to Australian Individuals at good rates.
Capital 19 Offers trading on both US and ASX to individuals at higher rates.
I have no experience of either of these,and would be interested to hear from anyone using them to trade options.
I am aware that this discussion possibly belongs in "Brokers Forum".but I put it here because it concerns solely Options spread trading.
