I've put the standard ROC indicator (Period set to 1) that comes with Ninjatrader 8 on a daily chart.
I only want to to do the calculation for the last 10 bars (with the Indicator property Calculate set to 'On price change').
The problem is however Ninjatrader needs me to add 28 bars to display the indicator only for the last (current) bar. There is NO indicator value plotted for the previous 27 bars. If I want to display more bars with the indicator displayed Including the current daily bar), I need to add more bars on the chart..
Does anyone know why this is?
Thanks,
