I wonder, but from my experience technicalist use indicators too. Fundamentalist use indicators and even Sentimentalist LOL use their own indicators. Naked trading is indicator-less, use those candlestick as the indicators or a thing to decide your next step whether to open a position or closing the position, basically you just use it, so still use indicator to me.
Technically you are correct. lol Traders use methodologies which gives them indication of what market may do next. So it can be called indicators. But let's not over complicate things and the way each type of trader describes themselves will be better to call them that.
