I just checked the website and under TPO I find the following FAQ
unless 'based on NT data' simply means the source data is from there but then it's implied that gets stored somewhere else, the mystery deepens.... mmmh..

just for balance put yourself in the guys shoes. He is a talented programmer and is offering a product that allows significant cost saving compared to pro trading tools, TT & CQG are recognised as industry standard. He could easily command a high hourly rate for his programming expertise. The main reason people by his software is to save money, these people then contact the guy asking to tweak this or modify that for FREE. It sounds like his customer services skills need improving however he is actually being asked to give his time for free. Why should he do that? If I were running a business or trying to provide for my family I certainly wouldn't do it for free.
just trying to add perspective to some of the posts in this thread.
when you look at TPO charts (which usually means 30 minute brackets) you don't need tick data. For volume profiles you can show that building profiles from 1 minute data gives a reasonable accuracy compared to building profiles from 1 tick data (although the latter is more accurate of course). I did a study on that a few years ago that compared the difference in price for the E-Mini S&P 500 Volume Point of Control (VPOC) over a sample size of 1088 trading days, when calculated from tick data and from minute data. On roughly 30% of the days there was no difference in the VPOC at all. The first standard deviation (meaning the area where 68.2% of the values are found) was only four ticks wide, meaning the difference was only two ticks or less 68.2 % of the days.
As you are not trying to land a space ship based on this data, the accuracy is good enough to use it for trading in my opinion.
I think it is accurate - see the jpg below - comparing Jigsaw total volume with fin-alg volume. TPO levels match as well.
I've used the fin-alg indicators for several years - they're cheaper than Market Delta and are just about the same.
