Re TD
Yr right…mny years ago I was a client of the Co that developed Prophet Charts…..I used them as a TA/Data source…they ended up via various take overs as part of TD….who quickly closed down the TA/Data choice, unless u signed up as a trading client and to add to the insult in my case, they refused to take any UK based clients…so I had to quit and lose all my TA/Data source.All this just happened….I switched to Tradingview…..not as good but I had no choice…grr
All they want is the client list.
U can get Debian Linux, which Ubuntu is based off running ThinkorSwim….I did it on Linux Mint.
Try this link…I think it was the one I used….once it was installed it ran perfectly.
