According to all the Ichimoku literature I have the Chikou Indicator is price shifted back by a default of 26. That means that nothing is plotted for the most recent (Shift) 26 bars.
From the Zorro Help Manual
"Chikou(int Shift): var
Chikou line belonging to the Ichimoku indicator; simply the Close shifted forward by Shift (optional; default = 26). Uses the current asset price series. Source code in indicators.c."
My tests confirm that the indicator behaves as per the incorrect manual.
Needs a fix please.
