A long, long, time ago, I can still remember – when moving averages were plain and simple. Nothing weighted or exponential, dynamic or otherwise (nowadays considered moribund perhaps). Traders used to use 10 and 20 day moving average crossovers to generate buy and sell signals; fund managers, who had time on their side, opted for 50 and 200 day ones, again only crossovers.

Only economists use line charts.  We technical analysts have developed far more sophisticated methods, first bar charts, then bar charts with opening and closing levels which morphed into candlesticks, not forgetting those with no time scale along the bottom like Point & Figure, Renko, and the Japanese Three Line Break.
