Hi all,

I'm relatively new to metatradted. I'm trying to create an indicator in MQL5 with 5 multicolored plots but only one is showing up when I run it. Can anyone show me how to do this or share an indicator that has multiple multi-colored plots? Thanks!

There is a bug in MT5/mql5. (and in your code too but that's an other matter ;-))

Replace your SetIndexBuffer/PlotIndexSetInteger by :

// CurrentEMA
   PlotIndexSetInteger(0,PLOT_DRAW_TYPE,DRAW_COLOR_ARROW);
   SetIndexBuffer(0,CurrentEMA_Buffer,INDICATOR_DATA);
   SetIndexBuffer(1,CurrentEMA_Colors,INDICATOR_COLOR_INDEX);

// H1EMA
   PlotIndexSetInteger(1,PLOT_DRAW_TYPE,DRAW_COLOR_ARROW);
   SetIndexBuffer(2,H1EMA_Buffer,INDICATOR_DATA);
   SetIndexBuffer(3,H1EMA_Colors,INDICATOR_COLOR_INDEX);

// H2EMA
   PlotIndexSetInteger(2,PLOT_DRAW_TYPE,DRAW_COLOR_ARROW);
   SetIndexBuffer(4,H2EMA_Buffer,INDICATOR_DATA);
   SetIndexBuffer(5,H2EMA_Colors,INDICATOR_COLOR_INDEX);

// H3EMA
   PlotIndexSetInteger(3,PLOT_DRAW_TYPE,DRAW_COLOR_ARROW);
   SetIndexBuffer(6,H3EMA_Buffer,INDICATOR_DATA);
   SetIndexBuffer(7,H3EMA_Colors,INDICATOR_COLOR_INDEX);

// H4EMA
   PlotIndexSetInteger(4,PLOT_DRAW_TYPE,DRAW_COLOR_ARROW);
   SetIndexBuffer(8,H4EMA_Buffer,INDICATOR_DATA);
   SetIndexBuffer(9,H4EMA_Colors,INDICATOR_COLOR_INDEX);

I was wrong in my previous post, this is not a MT5/mql5 bug, I should not work in such things in the night

The problem is in this line :

#property indicator_type12  DRAW_COLOR_ARROW

must be

#property indicator_type2  DRAW_COLOR_ARROW
