i can say one thing for sure - from personal experience: it is easy to get on the wrong road and keep travelling on it, for a long long time, with the mistaken notion that you are going somewhere.
so it is not whether we use market structure, price action, indicators, market breath ,momentum, but whether we know where we want to go.
The thread topic highlights a basic dilemma and decision that has to be faced.at the start.
both price action and indicators measure the same thing on the chart.
Indicators suffer from one disadvantage: the look back period which is always fixed.
which means it compares present conditions to conditions present X periods away.
RSI compares present relative strength to the relative strength X periods away.
Price action, market structure has no such restriction and so is more flexible.
but both gives the same information
A fixed look back period is what makes indicators, IMO, totally absurd. it is useful but it may be useful maybe 10% of the time,IMO.
there is one thing all traders look for and it is strength of the market which determines market direction.
