Selected Date Range
A bar range, for processing, can be stipulated at the formula level.
The following code plots the Close, over a four month period, using the DateNum function (BarIndex can also be used in a similar way).
1 2 3 4 5 6 7 8 9 10 | //P_SelectedRange ///////////Plot a selected date range in the middle of chart using BarIndex or DateNum //Plot(IIf(BarIndex() >= 978 AND BarIndex() <= 988,C,Null),"",1,1); Plot(IIf(DateNum() >= 1050101 AND DateNum() <= 1050430,C,Null),"",1,1); ///////////Plot a selected range at the end of a chart LastBarIndex = LastValue(BarIndex()); //Plot(IIf(BarIndex() >= LastBarIndex - 10 AND BarIndex() <= LastBarIndex(),C,1)," ",8,1); //Plot(IIf(BarIndex() >= LastBarIndex - 10,C,1)," ",8,1); |
If the last line of code is uncommented the Close,for the last 10 bars only, will be plotted.
The formula can be adapted for use in other modes (filter, scan etc).
