just variable names (btr to have meaningful names that make reading/programing/maintaining code easier for U) - nothing special about them long as u follow rules regarding indicator buffer use.

Do I need to keep the names of the buffers originally named by MT4:
ExtMapBuffer5[]
or can I replace the names e.g. according to the color they are paintend like
smaBlue[] ??
Or does this mix up MT4?
