Two more tools, and the point at which adding stops helping
MACD
The Moving Average Convergence Divergence is the difference between two EMAs (usually 12 and 26), plotted as a line, with a 9-period EMA of that line as a signal, and the gap between them as a histogram.
Read plainly: MACD is a moving average crossover, drawn as an oscillator. It is not a separate measurement. It is the same information from the previous lesson in a different shape.
That matters because it settles the confluence question immediately: using MACD to confirm a moving average signal is checking one thing twice.
Its one genuine advantage is the histogram. The rate at which the gap narrows shows momentum decelerating before the lines actually cross — an earlier read than the crossover itself. Useful as a warning that a move is tiring; useless as an entry.
Bollinger Bands
A moving average with bands at two standard deviations above and below. The bands widen when volatility rises and narrow when it falls.
What they measure: volatility, not direction. This is the single most misunderstood point about them.
