Havent read the entire thread, sorry....but have you tried Sierra Chart? Its rock solid stable. Im with IB but you couldn't pay me to use that piece of crap TWS software.
Bit of a learning curve involved and 'support' can be sketchy (they basically tell you to go read the help file) but you wont find any better platform imo. It also comes free with some brokers, I pay for mine though.
On related topic ... I am looking for charting package that can plot volume chart. I am currently using esignal and I'm keen to explore if there are other available options.
Www.marketdelta.com and investor r/t from www.linnsoft.com are the packages to look at. They are the same software. Marketdelta costs a lot more but it sounds like investor r/t will meet your needs as it has the volume studies.
Are you just playing your superiority card? Perhaps you could supply some info. I have written all sorts of indicators. From the studies I can open another chart automatically, change the bar interval automatically, read the data from another chart, read the data from another study on the same chart, read the data on a study from another chart, set alarms, auto trade with quite a few brokers... Manually I can look at several charts on the screen, have the cursor track all of them or not, change the x and y scales with the mouse/keypad...
Tell me something new, pal. This is all "boring" - known - stuff being possible in other platforms as well. Tell me something exceptionally new one. So far you bore me to death.
