Hi Bob, the MT4 indicators are very different tools indeed and they won’t ever replace ST. They suit a different style of working. The indicators require more “screen estate”, and work on the principle that you have many charts up, each with a different piece of the puzzle … whereas ST is more of an “everything on one chart” approach. That idea extends to the other things you mention: the indicators are much more flexible in terms of the nominal model, and so the need to modify is not so great (although it can be done as a matter of interest). And pinning is definitely more limited with the indicators.
It all boils down to a different approach. The indicators suit some people, and ST suits others better, and that’s the way it should be. Different tools for different approaches.
Personally I find myself working more with the MT4 indicators now … but I do start every day with ST
