Way I see it, way too many traders are too lazy to really learn charting, they study a little and think they known it then go to way too many indicators. Market trend higher highs/higher lows or lower lows/lower highs. After a move in one direction and you can make a rectangle of highs or lows, you know more than most, either get out, go the other way, hedge or do a mixture. Missile shots is another favorite screaming up or down hard often reverses.
One indicator is fine to show trend or containing price from across the room where you might be doing treadmill or weights. People do not take the time with indicators either, they should examine price and the indicator on what is expected on every single bar and when something is expected and does not make expected move then you might have a gift that others never notice.
But thankfully people are very lazy, just gets easier and easier in passing years at extremes.
