Ichimoku Kinko Hyo: Complete Trend System in One Chart

Ichimoku Kinko Hyo — Japanese for "equilibrium chart at a glance" — is a self-contained trend system that shows trend direction, momentum, and dynamic support/resistance simultaneously using five components derived from midpoints of high-low ranges.

Section 1: Core Mechanics

Ichimoku was developed by Japanese journalist Goichi Hosoda over 30 years of testing before being published in 1969. Unlike oscillators, every Ichimoku component is price-derived and plotted on the price chart. The cloud (Kumo) acts as a forward-projected support/resistance zone visible before price reaches it.

Formulas

Tenkan-sen (Conversion Line) — 9-period midpoint:

Kijun-sen (Base Line) — 26-period midpoint:

Senkou Span A (Leading Span A) — plotted 26 bars forward:

Senkou Span B (Leading Span B) — plotted 26 bars forward:

Chikou Span (Lagging Span) — plotted 26 bars backward:

The Kumo (Cloud) is the filled area between Span A and Span B, projected 26 bars into the future. Thick cloud = strong S/R. Thin cloud = weak S/R, easy to break.

Inputs

• High, Low, Close for each bar
• Period 1 (Tenkan): 9 (default)
• Period 2 (Kijun): 26 (default)
• Period 3 (Span B): 52 (default)
• Displacement: 26 bars (for Span A/B forward projection and Chikou backward shift)

Parameters

Output

Five series plotted on the price chart: Tenkan-sen, Kijun-sen, Chikou Span, Span A, Span B. The cloud fills the area between Span A and Span B. When Span A > Span B, cloud is green (bullish). When Span B > Span A, cloud is red (bearish).

Visual Behavior

• Price above the cloud = bullish bias
• Price below the cloud = bearish bias
• Price inside the cloud = neutral, transition, avoid trading
• Green cloud = bullish future support projected forward
• Red cloud = bearish future resistance projected forward
• Tenkan above Kijun = short-term momentum bullish

Section 2: Interpretation & Signals

Signal Hierarchy (weakest to strongest)

Signal 1 — TK Cross (Tenkan-Kijun Cross)

When Tenkan crosses above Kijun, short-term momentum turns bullish. Classify by position:

• Strong TK cross: occurs above the cloud
• Neutral TK cross: occurs inside the cloud
• Weak TK cross: occurs below the cloud (fade signals only)

Signal 2 — Kumo Breakout

Price breaking through the cloud is the strongest Ichimoku signal. On the breakout bar:

• Cloud must be clearly separated from prior price action
• The thinner the cloud at the breakout level, the weaker the future resistance
• After breakout, the cloud acts as support on pullbacks

Signal 3 — Chikou Span Confirmation

Plot the current close 26 bars back. When Chikou Span rises above the price from 26 bars ago, it confirms the current move has historical momentum behind it. This is the most underused Ichimoku component.

• Chikou above price from 26 bars ago → bullish confirmation
• Chikou below → bearish
• Chikou inside price action → ambiguous, wait for clarity

Best Market Conditions

Ichimoku thrives in strong trending markets with clear directional bias. It struggles in low-volatility, tight-ranging conditions where Tenkan and Kijun flatten and the cloud compresses.

Section 3: Pass vs. Live — Real-Time Reliability

Chikou Span, though plotted 26 bars back, uses the current close — it updates live. On bar close it locks. No historical values change. The forward-projected cloud (Span A and Span B) uses data from the current date and was calculated at that bar's close — it does not change retroactively.

Section 4: Practical Use Cases

Real example: USDJPY weekly — through 2022, price held firmly above the weekly Ichimoku cloud as the yen weakened sharply. The cloud was thick and green (bullish) below price, providing clear visual support. USDJPY ran from 115 in January 2022 to 152 in October 2022 — a 37-yen move — without ever closing below the weekly cloud top. Every pullback to the cloud was a re-entry opportunity.

Section 5: Pseudo Code

INPUT: high[], low[], close[], t1=9, t2=26, t3=52, disp=26

PROCESS:
  Step 1: Tenkan-sen for each bar i (needs t1 bars):
            tenkan[i] = (max(high[i-t1+1:i+1]) + min(low[i-t1+1:i+1])) / 2

  Step 2: Kijun-sen for each bar i (needs t2 bars):
            kijun[i]  = (max(high[i-t2+1:i+1]) + min(low[i-t2+1:i+1])) / 2

  Step 3: Span A — compute on current bar, plot disp bars forward:
            span_a_raw[i] = (tenkan[i] + kijun[i]) / 2
            span_a[i + disp] = span_a_raw[i]

  Step 4: Span B — compute on current bar (needs t3 bars), plot disp bars forward:
            span_b_raw[i] = (max(high[i-t3+1:i+1]) + min(low[i-t3+1:i+1])) / 2
            span_b[i + disp] = span_b_raw[i]

  Step 5: Chikou Span — shift current close disp bars back:
            chikou[i - disp] = close[i]

  Step 6: Cloud color at each future bar j:
            cloud_bullish[j] = span_a[j] > span_b[j]

OUTPUT: tenkan[], kijun[], span_a[], span_b[], chikou[], cloud_bullish[]
EDGE CASES:
  - Need t3 bars minimum before Span B is valid (52 bars)
  - Span A and Span B plot ahead of current bar — treat future bars as projection, not signal
  - Chikou plots 26 bars before the current bar — compare against price at that historical bar
  - When tenkan == kijun: no TK cross possible — market in equilibrium (flat midpoints)
