Description:
The Ichimoku study developed by Goichi Hosoda from Japan.
Formula Parameters:
- Turning Line Periods: 9
- Standard Line Periods: 26
- Leading Span 2 Periods: 52
- Displacement: 26
- Ichimoku Cloud Style: Striped - [Stiped, Solid]
- Ichimoku Could Colo: grey
- Line Color: Turning Line: red
- Line Color: Standard Line: blue
- Line Color: Delayed Line: magenta
- Line Color: Leading Span 1 Line: lightgrey
- Line Color: Leading Span 2 Line: purple
- Line Thickness: Turning Line: 1
- Line Thickness: Standard Line: 1
- Line Thickness: Delayed Line: 1
- Line Thickness: Leading Span 1 Line: 1
- Line Thickness: Leading Span 2 Line: 1
Notes:
Bullish signals occur when the Turning Line crosses above the Standard Line, and bearish when crossing below. The shaded area between Leading Span 1 and 2, called the cloud, represents support and resistance. The Delayed Line is simply the close offset by 26 periods to give a quick comparison of today's price to that of 26 periods ago.
