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.
