Indicators
See allWhat each one calculates, and the market condition it stops working in.
Moving averagesMoving Average: What It Is, How to Calculate One, and How Late It TurnsA moving average is the average close over the last N bars, redrawn every bar. Worked on real S&P 500 closes, then timed at 26 market lows since 1950.
IndicatorsWhat Is RSI? The Relative Strength Index Worked by Hand and Tested on Five FundsRSI scores recent gains against recent losses from 0 to 100. Worked by hand on SPY's 30 Oct 2026 close, with 70, 40 and 30 tested on five funds since 1994.
IndicatorsWhat Is MACD? Formula, How to Read It, and a Worked SPY ExampleMACD is the 12-day EMA minus the 26-day EMA, with a 9-day signal line and a histogram. Worked by hand on SPY's 30 Oct 2026 close, plus 33 years of data.
IndicatorsWhat Is VWAP? The Formula Worked by Hand on Real SPY BarsVWAP is the volume weighted average price from the open. Worked by hand on SPY's 16 Oct 2026 bars, plus 170 sessions testing what its 10:30 side said about the close.
IndicatorsBollinger Bands: The Formula Worked on 20 Real SPY ClosesBollinger Bands are a 20-day average with lines two standard deviations either side. Worked by hand on SPY to 30 Oct 2026, then tested on 34,767 ETF sessions.
IndicatorsWhat Is the Stochastic Oscillator? Formula, %K and %D Worked on Real SPY PricesThe stochastic oscillator shows where the close sits in the last 14 bars' range. A real SPY %K and %D worked by hand, plus what 80 and 20 meant since 1993.
Moving averagesExponential Moving Average: Not FasterAn exponential moving average lets weight decay instead of stopping. It reacts sooner to new bars, yet its center of mass matches the simple average: 9.5 bars.
IndicatorsWhat Is ATR (Average True Range)?ATR measures how big a bar has been, in price. It has no direction in it — it rose during the selloff on the chart below — and its real job is sizing stops.

Who writes this
I started learning to trade in 2017 and went full time in 2020. Before that I was a marketing manager, which mostly means I am used to reading numbers and reporting what they say rather than what somebody hoped they said.
Nearly every page here has a section on what the idea looks like when it fails, because that is the part I could not find anywhere when I needed it.
