You have it correct, unlike anyone else I've used almost all of these, and have used all of the ones that work including TT and CQG which you can say are more institutional grade, but CQG is a bit unique how it works and TT is Futures based but they work with per second datasets well, along with Tradestation and eSignal platforms.
You can actually get Metatrader to work with per second data on MT4 and MT5 but for order execution and initial analysis, it doesn't work well with detailed analysis where you need the institutional platforms to confirm trade setups to increase the probability.
The main problem we had was point 2 (Speedy with lots of small charts on the screen / ability to link them) to be able to draw charts and move to another machine with the same drawings loaded, have 250,000 data points across all the charts updated in realtime, the ability to change all chart instruments in one click, and auto rotate.
You may find one in a platform but not all of them, so we had to build it ourselves, for point 3 use Parallels if you have a good mac, or you can just use a windows VPS and remote desktop in to it, there are advantages including being able to monitor across devices, screen dimensions stay fixed, and the most important to be able to pinch zoom, you truly have no idea how much it changes your decision process making you more profitable.
but is there a holy-grail?
cahrting and analysis aside, i want a platform that allows me to see lots and blocks, and let me choice which one to exit, rather than bland into cost averaging.
