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

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
