Thank You.
I have "referenced" the TD Ameritrade and ToS "snap-shot" data-feeds vs a Level One "IQ-Feed" quote feed from DTN and the difference is downright alarming.
I've even "referenced" the ToS professional/institutional platform called ThinkPipes* vs the basic ToS trading platform with the "snap-shot" feed and the difference was night and day too.
*This was back in December of 2009, and I believe that ToS needed to see a minimum account balance of $250k and a minimum of 500 trades per month. The average ThinkPipes account had a balance of $1 million and executed, on average, 1,000 trades per month. The account was entirely separate from TD Ameritrade, and it cleared thru Penson Financial.
I'm not even sure if ToS even offers ThinkPipes anymore.
I believe that it is now under TD Ameritrade and designed specifically for investment advisors.
If you are scalping and day-trading, a "snap-shot" data feed is a downright non-starter... especially in this highly volatile environment where a tremendous amount of quote volume per second is being generated.
End of Story.
