This program with a little more work could be a great program, however it has caused my machine to crash many times before I managed to discover what the problem was. There are two types of tick data charts within the package "Tick Chart" and "Constant Tick", it's the latter that cause the problem. This chart downloads a huge amount of data, open this type of chart a couple of times and your machine suddenly has no memory left. Stay away from the Constant Tick charts and the program works fine.
Technical support is prompt, polite however I found the support to be ineffectual, I ultimately had to solve the problem myself. The help files are also very poor indeed.
Within the package the graphics are good also the range of indicators is fairly extensive, the package has many other features not related to TA, all seem to work fine.
This company also provide the data-feed, this has proved to be very smooth and reliable. I would have no problem recommending the feed.
Any views expressed here are my own, I have no connection with any software/data-feed companies.
