I fibbed from 471$ (0%) to 2326$ (100%) just like you did with MotiveWave and projections perfectly match.
I think the problem is that when moving the tool the initial fibbed range changes. Even if you lock it you can't move it at all and makes it therefore useless.
Unfortunately, that's not how I work projections, I need to move it, so it won't work at all for me. I have pinescript code for making fib lines off three points, but it just is slow to use when I can drag and drop in MW. So, don't care to do my EW work on Tradingview.
