Help! Why does my indicator draw vertical lines on the main chart for unassigned lower window technical's !?

[mikegreen]

Any suggestions as to why would be appreciated.

With a small amount of code, it is useful to post the code using SRC button. I have added it for you.

#property indicator_chart_window

 means that the buffers are drawn in the main chart window.

Values such as CCI will often appear as vertical lines 

[mikegreen]

does this effect the final signal outcome?

and what happens if I remove  #property indicator_chart_window will this effect the visual view?

mickeyferrari:

does this effect the final signal outcome?

double CCI[];
double CCIback[];

seems to me that you don't use these 2 buffers for anything as the CCI calculations are done with variables. As you don't want lines drawn for them, you may as well remove them completely. If you intend to use them in further development of the code, you could set them to DRAW_NONE.

and what happens if I remove  #property indicator_chart_window will this effect the visual view? 

 Probably that is the default and removing it will not solve your problem.
