Every term is defined twice: once the way a filing would put it, and once the way somebody would explain it to you across a table. The second one is usually the one that sticks.

Signal line
Technical analysisA nine-period EMA of the MACD line, used as the trigger for MACD crossovers.
In plain terms
The classic MACD signal, and a late one. It whipsaws badly in ranging markets, which is precisely why the zero-line filter exists.
Smoothing
Technical analysisAveraging price data to suppress short-term noise, as Heikin-Ashi does by blending each bar with the one before it.
In plain terms
It buys clarity by discarding information, and it flatters backtests badly — because the whipsaws it removed are exactly the ones that would have stopped you out live.
SuperTrend
Technical analysisAn ATR-based trailing indicator that flips between acting as support and resistance.
In plain terms
Very popular with Indian intraday traders. A trend-follower, so it whipsaws in ranges.
