Paul - I'm getting confused now! Like Ian, my understanding is that to get eSignal Nasdaq level 2 ($9 per month) you have to first subscribe to Level 1 ($1 per month), and also pay $50 for :-
"(eSignal requires a monthly surcharge of $50 per month for monthly subscribers and $20 per month for prepay subscriptions in addition to exchange fees for one or all Market Depth services.*)"
So total for usable level 2 is $1 + $9 + $50 = $60 per month, unless you go for the annual pre-pay, in which case the $50 surcharge drops to $20 per month, making a total of $30 per month.
Are you saying that there is some type of saving for IB users, 'cos if so it is not apparant from the site.
