KCalhoun, I have been using TC2K from V7 (still use today) to V20,for at least 23 years . I especially like the notes I can add myself to the charts downloading from various websites, ie: Div channel, Finvitz, or Seeking Alpha. The PCF's are also fantastic especially setting them up with my criterias. The only major problem is I need fibonacci and after evaluating a few other platforms, I am still stuck with Sierra. Also the data stream comes from IB where at times I see price discrepancies ( I use IB brokerage) but if you need help feel free to PM me.
