good improve for this AFL for over the time… thanks

Hi, Could you please explain more about Dashboard. For example:
What’s SR/RS/EF mean?

3. sal157011

I know you didn’t ask me, but just trying to help I must say:
SR means spread or high-low of the bar compared to the average spread of the last 40 bars.
RS means result or the absolute value of the difference between the close of the previous bar and the present bar,
compared to the average result of the previous 40 bars.
EF means effort or the volume of the present bar compared to the average volume of the previous 40 bars.

I think the lines 898, 908 and 918 are not correct.

GfxGradientRect(x+55,y+130+x3,x+65,y+230,colorPaleBlue,colorBlue); // line 898, bellow the correct one
GfxGradientRect(x+55,y3 ,x+65,y+230,colorPaleBlue,colorBlue);

GfxGradientRect(x+75,y+130+x4,x+85,y+230,colorOrange,colorDarkRed) ; // line 908, bellow the correct one
GfxGradientRect(x+75,y4 ,x+85,y+230,colorOrange,colorDarkRed) ;

GfxGradientRect(x+95,y+130+x5,x+105,y+230, colorPaleGreen,colorDarkGreen); // line 918, bellow the correct one
GfxGradientRect(x+95,y5 ,x+105,y+230, colorPaleGreen,colorDarkGreen);
