Quote from osorico:
And that is exactly why IB sucks, at least for futures trading.
As a business, if a supplier is not consistent and reliable you'd find a different supplier. In the case of IB you just sit quietly in the corner as your prices go up 50% in one fell swoop and you adjust the core of your business? That's exactly what IB is hoping you do.
As a business, I'd hate to have myself levered up so that the first volatile thing that happens I'm out of business.
But let's not blame IB for protecting their business just because you and others want to roll the dice.
