My apologies @Richard_Able-Trading I did not realise you required a response.
If you are referring to ‘Who has the least data / info to work with?’, totally agree naked price action has the least to work with.
But you could take this whole data thing to extremes such as requiring all the indicators on every possible timeframe, all fundamental analysis from all market participants, all sentiment surveys, COT, PCR, every bank liquidity ratio, all the Fed chairman speeches for the last ten years.
Are we going to include Dow theory, Elliot wave, the Kondratieff wave? Sun spots? Full and half moon cycles? Bradley turn dates?
I mean, where does it all end?
I do agree, one of the reasons I was attracted to technical analysis in the first place (maybe wrongly) was because it summed up all the data there within the price itself.
Making things simple.
I’m a simple person, requiring simple answers - if that means I’m a weak hand or dumb money I can live with that.
I’ve been called much worse.
These days I am more aware of the limits of TA (most of which I think is voodoo), but it’s still a great place to start.
As for indicators I don’t ever recall Jesse Livermore talking about MACD/RSI divergences on multiple timeframes (granted he did commit suicide).
I don’t recall Darvas doing so either or for that matter Ed Seykota, Richard Dennis, the whole turtle crew etc
There are IMO as many ways to analyse price as there are participants and ultimately the successful trader will stumble across one that suits him or her.
It may be your way, it may be mine, it may be a combination of the two.
