If the software was written in some obscure old language and no one but Jerry can support the beast some clever young programmer should come along and look at it and then start programming (using JAVA) charts that look and act just like QT, along with all the other bits that make it superior to anything else that is out there. Believe me, the heavy lifting has been done already. Reverse engineer the thing and all the people who loved QT will flock to the new one. For people who know programming this is not rocket science even though the rest of us might have no clue where to start.
To be successful in trading there are some of us who don't need 18 million bells and whistles. Good charts, simple trend line drawing tools, some Fibonacci along with that awesome symbol list with it's properly blinking price, bid, ask, high and low prices, combined with the averages printed at the top are about all I need. When it's gone my 'eye' into the market will go from 20-20 to something less. I'm working on a replacement but nothing quite like it is showing up.
