Hello,
Don't worry. In Poland the biggest telecom (Telekomunikacja
Polska) tried that on DSL subscribers.
They were limiting download speed limit after reaching certain
threshold for about two years,
but competing companies (even though much smaller) that were
NOT imposing any limits started to gain market share because people
did not like limits and moved to competition. That scared
off the biggest one and they finally dropped the idea and now there are no
limits.
US way more competitive market won't allow this idea to
survive.
As to your question, it depends whenever data source
compresses the stream or not, how many trading hours are, etc.
For uncompressed stream of frequently traded instruments that
can be more than 100000 ticks per day x 24 bytes (ticker ID, timestamp,
price, size)
minimum per tick you may end up with 2.4MB
per symbol per day. Note that feeds may use more bandwidth than 24 bytes per
tick if source is not very optimized
for transfer size.
Best regards,
Tomasz Janeczko

Internet Usage
Hi,
Looks like the future will bring a type of pay as you use for internet
bandwith, Time Warner is testing it and Comcast is slowing down volume
users.
Does anybody have any idea of what real time data, say for 100
symbols amounts to for a month's of usage?
Here is a link for one story about it

Thanks,
Dave
