- Higher high / higher low (HH/HL)
- Successive swings each above the last: the signature of an uptrend.
- Lower high / lower low (LH/LL)
- Successive swings each below the last: the signature of a downtrend.
- Break of structure (BOS)
- Price breaking a prior swing in the trend's direction.
- Change of character (CHoCH)
- The first break against the prevailing trend - an early sign the trend may be shifting.
- Area of interest / zone
- A price area where the market has reacted before.
- Pullback
- A move against the trend, back toward a zone or band.
- Confluence
- Several factors at one price, e.g. a zone and a moving average.
- Multi-timeframe (top-down) analysis
- Setting bias on higher timeframes (weekly/daily/4H) and refining entries on lower ones (1H/30m).
- ATR (Average True Range)

- The line between the flag bands, leaning toward the side of the current trend.
- MACD histogram
- The gap between the MACD line and its signal line. Green above zero, red below.
