There are four common ways to display price data. Each has its strengths:
📈 Line Chart
Close prices only · easy to read
📊 OHLC Chart
Open/High/Low/Close · professionals
🕯️ Candlestick Chart
Like OHLC, more readable
🔵 Heikin-Ashi
Smoothed · trends clearer
Candlestick charts are the standard for active traders — they show all four prices (OHLC) in one candle and make price movements intuitively readable. All strategy sections in this handbook use candlestick charts.

Each Japanese candlestick shows four pieces of price information at a glance — like a clock that simultaneously shows the high, low, start and end of a period:
⬆️
High — Daily high price
The highest price of the period. Buyers tested this level — sellers maintained the upper hand and pushed the price back down.
✅
Close (C) — Closing price
Last price of the period. Green candle: Close above Open → buyers won. Red case: Close below Open.
🔔
Open (O) — Opening price
First price of the period — the starting gun. For the red candle it sits at the top; the price fell from here.
⬇️
Low — Daily low price
The lowest price of the period. Sellers tested here — buyers intervened and supported the price.
📏
Body length = balance of power
Long → clear winner. Short → undecided. Long wick → level tested but rejected.
💡 Mnemonic: 🟢 Green = rose (Close > Open). 🔴 Red = fell (Close < Open). The coloured body is always the distance between open and close.
