Finance Lesson 7 done.
You can read a candle: its body and color, its range, both wicks, the gap from the day before, the daily change, and whether volume backed the move. Next in technical analysis: moving averages and the crosses traders watch.
What you're learning
Each candle is one trading day with four prices: open, high, low and close. The thick body spans open to close: green (up) when the close is above the open, red (down) when it's below. The thin wicks show how far the price went beyond the body during the day.
Volume is how many shares changed hands. Traders read a big move on high volume as more meaningful than the same move on a quiet day, because more money took part in it.
Candles describe what happened; they don't predict what happens next. Prices are Apple's real daily prices from October 20 to November 2, 2022 (Yahoo Finance, unadjusted), volume rounded to 0.1 million shares. Educational content, not investment advice.
