Why would IB need a frontend?
They always had a frontend that evolved over the years and brought IB many satisfied customers.
The recent loss of focus due to the charting and other gee-whiz stuff is worrisome, without even mentioning the catering to an odd-dozen of socalled 'API' outfitties.
IB, stick to what is the core of your business. An example of the past is Quote.com, now swallowed up by lycos, albeit not 100% identical with IB's business. Quote.com had a good thing going 5 or 6 years ago with an excellent reputation for its software SDK/API. Till they started to put bells and whistles on and turning it into a 'do everything gismo' called 'Live Charts', top heavy, totally useless for their bread and butter quote distribution business. Lots of complaints and defections for all the years ever since. Simply do an ET search if you want to know more.
IB, you are great. Make sure you stick to essentials for traders. All the rest can be bought at many places. Shake off the hungry crowd continuously crying for cheapies.
