Could someone with more ability then me modify the supertrend indicator to plot only the uptrend?
I tried, had to accept that i couldn't get it working.
Thanks in advance.

Thanks for the reply cory.
Its good to see a fellow member from the DC metro area.

Setting the background color to chart color wont do what i need.
Because the stop value is still plotted on the chart and picked up by the spreadsheet.

If there was a separate StopLong and a StopShort instead of one "Stop" variable , I would be able to choose ignore to keep the StopLong or the StopShort value from showing up in the chart and being captured by the spreadsheet.

if works remember to change sc.FreeDLL = 1; to sc.FreeDLL = 0;

Thanks crazybears,
That worked for the long side, but it doesn't allow me to be able to select ignore for the short side or provide a separate named variable value plotted on the chart for the long and short side.
ie:
StopLong
StopShort

Hi Renko123

maybe i didn't understand but you didn't want to plot only the up trend of super trend ?

do you want the choice to plot only the up or the down trend ?

Yes, crazybears.

If possible the ability to choose to plot either long, short or both on the chart.
something like choices in the input.
SCInputRef PlotLong = sc.Input[3];
SCInputRef PlotShort = sc.Input[4];

With the supertrend directional stops "Stop" or "Stop1" plotted on the chart depending on which input was chosen.

Thanks.

Thanks crazybears for the coding changes,

However some problems still remains.
The subgraph SuperTrend(SG5) stop name for long or short is still the same.


There needs to be a separate subgraph stop name for each the long and the short trend.
ie:subgraph
StopLong(SG5)
StopShort(SG6)

Another issue is when the option to show only the short stop is selected.
The stop is all over the place.
The stop moves up and down the short side trend.
