Ichimoku in NinjaTrader — NinjaScript (C#) Source

Ichimoku in NinjaScript is mostly midpoint math, with the wrinkle that plotting a line into the future isn’t something a normal plot does — so we compute all five lines and handle displacement with plot offsets. See the explainer for the components.

What you’ll need

• NinjaTrader 8
• New → NinjaScript Editor → Indicators → New Indicator, name it AlgoGenIchimoku

Handling the displacement

The code computes the correct values; displaying them shifted is the last step. In NinjaTrader you set a plot’s displacement with Plots[index].Displacement:

// In State.Configure, after the AddPlot calls:
Plots[2].Displacement =  Displacement;   // Senkou A forward
Plots[3].Displacement =  Displacement;   // Senkou B forward
Plots[4].Displacement = -Displacement;   // Chikou back

Gotchas

• Compute now, display shifted. Don’t try to write future values into [0] — compute the span value on the current bar and let the plot’s Displacement push it forward; use a negative displacement for the Chikou.
• The cloud fill. NinjaTrader can shade between two plots with Draw regions or a PlotStyle fill; the exact approach depends on your version, but the two span values above are what you fill between.
• Warm-up. Guard CurrentBar < SenkouBLen so the 52-period midpoint has data.

That’s the five-language set: Python, MQL5, Pine Script, EasyLanguage, and this one. Now test an Ichimoku system in AlgoGen.
