This is like when sierrachart thought exchange fees were too high and decided to setup their own exchange! Nothing was ever heard about it again.
After several years with Sierrachart and almost infinite patience with the dispute between Sierrachart and Rithmic, I deleted everything I had from Sierrachart on my computers. I was fed up with this yes no and back and forth ..... I researched the next platform for a long time and made a decision. MOTIVEWAVE won. Intuitive and the support is great.
I use MW too because I want to trade from my Mac. MW is decent with elegant user interface and support. However, I still need to use SC because some advanced features are not supported in MW. Also, MW was used to be buggy and I had to report the bugs constantly. I think it's improved but I find myself I still use two platforms at the same time (I use two simultaneous CME connections).
And yet again Sierrachart ..... Due to the lack of Rithmic support, I gave up prop trading and trade my own account with AMP. It was still saved in the cloud ... Lucky
