Ichimoku
Download scriptThis script is designed to display the Ichimoku Kinko Hyo (often referred to as the Ichimoku Cloud) on a trading chart. This is a comprehensive technical analysis tool used by traders to gauge market momentum, identify potential support and resistance levels, and determine the overall trend of an asset.
The logic of the script functions by calculating five distinct components based on historical price data (specifically the highest highs and lowest lows over specific timeframes). Here is a breakdown of how each component is handled:
Core Trend Components
- Tenkan-Sen (Conversion Line): This is the fastest-moving line in the system. The script calculates this by finding the midpoint between the highest high and the lowest low over a short period (defaulting to 9 bars). It reacts quickly to recent price changes.
- Kijun-Sen (Base Line): This is a slower-moving line that represents the medium-term trend. The script identifies this by finding the midpoint of the highest high and lowest low over a longer period (defaulting to 26 bars). It serves as a primary benchmark for the market's equilibrium.
The "Cloud" (Kumo) Components
The script uses the interaction between the two lines above to create the "Cloud," which helps visualize future sentiment:
- Senkou Span A: This is derived by taking the average of the Tenkan-Sen and the Kijun-Sen. It provides a smoothed representation of the current price momentum.
- Senkou Span B: Similar to the first line but based on a much longer timeframe (defaulting to 52 bars). It finds the midpoint of the highest high and lowest low over this extended duration.
The space between Senkou Span A and Senkou Span B forms the "Cloud." When the cloud is thick, it suggests strong trend stability; when it is thin or changing color (based on which line is on top), it signals potential shifts in market sentiment.
Lagging Perspective
- Chinkou Span (Lagging Span): This component plots the closing price of the current candle but shifts it backward on the chart by a specific number of periods (the Kijun period). By looking at where the past price sits relative to current price action, traders can identify hidden trends and confirmation signals.
Summary of Operation
The script automatically scans every historical bar on your chart to calculate these five values. It then renders them as lines and histograms so you can visually distinguish between immediate momentum, long-term support/resistance, and the overall "atmosphere" of the market trend.
