I've been thinking a lot about algorithmic trading and imagined interfaces where you can code or build your own strategy from some blocks; this is really something I'd like for myself. But it's a bit out of reach for me right now as such an app, in my opinion, would really need a lot to be built before it can be useful; not an easy MVP here.
Also, have you tried TradingView? What do you think about them? They have scripting for strategies and indicators. It is an array-based language, I think, somewhat similar to R, just simpler. Nevertheless, I was able to craft quite interesting things in there.
As for desktop apps vs web-based: desktop apps definitely have their uses and advantages. I'm not saying web-based is better, but I think it's just more approachable, and there are ways where some of the existing apps might be improved.
