Subbie,
It does seem to be an evolutionary process. People start off with lots of indicators probably because they seek a certainty that isn't present in trading. They start with indicators that tell the same thing (and are thus, more than usually useless) and then pare them down as they realize the ineffectiveness of those indicators. Indicators are the passion of analysts, price and s&r are the passion of traders.
Personally I wrote 1000s and 1000s of lines of indicator code for Sierra Chart even as I was abandoning indicators. I now have 1 ema on some of my charts and none on others. I have had (and I group them here so you don't have repeats - 1 is enough as you learn to drop them):
Trend: ema, sma, wma, hull mas, t3 mas, macds
Acceleration (oscillators): macd, stoch, cci, rsi
Acceleration might have gone too far: Oscillators at extremes + keltners and bollinger bands (range extension).
Acceleration decreasing (so trend might be stopping, divergence): macd, stoch, cci, rsi
Support and resistance: true horizontal s&r, trend lines, trend channels, moving averages that often provide the early bounce points in a trend.
I now only have the last one because when price trades over a well chosen ma for a while you can be more sure of current trend (but you can do just as well with progression of s&r (moving hhs and lls)) but most importantly because its a lazy way of drawing the initial trend line that price is likely to bounce at. So, one ma, because it saves me drawing trendlines and trend channels.
All else is great fun but essentially empty of meaning.
I wish you well. The faster you evolve to recognize and move through that emptiness the more likely you are to make it to being a trader.
