Clear filtersTimeframes and Multi-Timeframe Analysis
The timeframe decides what is signal and what is noise. The same price series produces contradictory readings at different aggregations, and both readings are correct.
Linear and Logarithmic Price Scales
On a linear scale equal distances mean equal dollars; on a logarithmic scale they mean equal percentages. Over long spans the two produce genuinely different pictures.
Chart Styles: Candles, Bars, Line, Area and Heikin-Ashi
Each style discards something different. Knowing what a style is throwing away is what stops it from misleading you.
Adjusted and Unadjusted Prices

Extended-Hours Data on a Chart
Whether a chart includes premarket and after-hours trading changes its bars, its gaps and every indicator computed from them.

Stepping through a chart bar by bar, with the future hidden. It is the only charting tool that addresses hindsight directly.

Plotting two securities together, or dividing one by the other. The second is more informative and is used far less.
Workspaces and Comparing Several Securities
Several charts on one screen. The value comes from them being configured identically, which is the only thing that makes the comparison real.
Reading Someone Else's Chart
A published chart carries a set of choices that are rarely stated. Establishing them is the first step in reading it, and most of them change what it appears to say.
