I include MA's as "indicators" (so, yes, I don't actually use those. I see that for some people a couple of moving averages and their relationship/relative gradients can be a useful way of defining whether or not there's a "current trend" within a specific timeframe, of course: I just despair a little of people trying to use them to time their trade entries and exits).
I don't count "volume" as an indicator, and I do use it, myself (actually in the form of "constant volume bars", so it's "being taken into account in the way my price-chart is constructed" rather than "being displayed").
I'm not "anti-indicator", like some people in the forum, and I acknowledge that some traders use them well and profitably.
On the other hand, I think that approaching the "learning stages" with the "tacit expectation" that they have some magic predictive powers and that they're the "main way to learn to trade" is hugely misguided, and I wish I'd known that much earlier than I did.
I'm biased, of course, as we all are, one way or another, on such subjects: personally, I became profitable after several years only when I abandoned indicators, so that's my biased perspective.
However, I do notice that all the people I know (in the industry and home/independent/retail traders) who trade successfully with indicators are (a) using them in conjunction with a decent understanding of price action parameters, and (b) typically not using them to time their trade entries and exits.
