Market Structure
8 termsBreak of Structure
(BOS)A *body* close beyond the most recent swing in the direction of the existing trend. Confirms continuation.
Change of Character
(CHoCH)A smaller-scale structure shift — often the LTF cousin of MSS — signaling intent to reverse.
Higher High
(HH)A swing high that is *above* the previous swing high. Part of bullish structure (paired with HL).
Higher Low
(HL)A swing low *above* the prior swing low. The 'defended' side of a bullish trend.
Lower High
(LH)A swing high *below* the prior swing high. Part of bearish structure (paired with LL).
Lower Low
(LL)A swing low *below* the prior swing low. Confirmation of bearish continuation.
Market Structure Shift
(MSS)A body close beyond the *opposing* swing — the trend just changed direction.
Swing High / Swing Low
A bar whose high (or low) is more extreme than the bar on each side. The fundamental unit of structure.
Liquidity
5 termsBuy-side Liquidity
(BSL)Stops resting *above* swing highs / equal highs. These are *short* stops — when triggered, they buy.
Equal Highs / Equal Lows
(EQH / EQL)Two or more highs (or lows) at roughly the same price — a magnet for stops above (highs) or below (lows).
Liquidity
Pools of resting orders (typically stop losses) at obvious levels. Big players need these orders to fill size.
Liquidity Sweep
A fast push beyond an obvious level that clears resting stops, then reverses.
Sell-side Liquidity
(SSL)Stops resting *below* swing lows / equal lows. These are *long* stops — when triggered, they sell.
ICT / Smart Money
9 termsBreaker Block
A failed order block that flips role — bullish OB that fails becomes bearish supply, and vice versa.
Displacement
A strong, body-driven candle that breaks structure — the signal that institutions moved size.
Fair Value Gap
(FVG)An imbalance between the wick of bar 1 and the opposite wick of bar 3 in a 3-candle sequence — formed by displacement.
Kill Zone
Time windows when liquidity moves and high-quality setups print — typically London open, NY open, NY PM.
Mitigation Block
A structural retest where prior imbalances are partially or fully closed by price.
Optimal Trade Entry
(OTE)A defined retracement zone (62%, 70.5%, 79%) where institutional re-entries cluster.
Order Block
(OB)The last opposing candle before a strong displacement — typically the institutional footprint.
Power of 3
(AMD)Accumulation, Manipulation, Distribution — the three-phase shape of most meaningful trading days.
Premium / Discount
Within a dealing range, upper half = premium (sell), lower half = discount (buy). Equilibrium is the midpoint.
Candlesticks
3 termsDoji
A candle where open ≈ close — pure indecision. The wicks tell the story, not the body.
Engulfing Candle
A candle whose body fully covers the previous candle's body — strong shift in control.
Pin Bar
A candle with a long wick rejecting one side and a small body opposite. Wick should be ≥ 2× body.
Chart Patterns
2 termsExecution
4 termsBreakout
A body close beyond a meaningful level (S/R, range edge, neckline) with displacement.
Confirmation
An LTF signal (rejection candle, MSS, CHoCH, structure shift) inside the HTF zone that triggers entry.
Pullback
A counter-trend move within an established trend — typically a retrace into structure before continuation.
Retest
Price returns to a broken level (former support/resistance) before the move continues.
Risk
4 termsR-Multiple
(R)1R = the dollar amount you risked on a trade. A 2R win = 2× your risk.
Risk Per Trade
The maximum % of your account you'll lose if a single trade hits its stop. Typically 0.25-2%.
Risk-to-Reward
(R:R)Ratio of risk taken to reward sought — 1:2 means risking 1R to make 2R.
Stop Loss
(SL)The price level at which you exit a trade for a defined loss. Placed using structure, not emotion.
