- MT4 has only RGB not ARGB.
So of course they don't work. Can't be done.Color Type - Integer Types - Data Types - Language Basics - MQL4 Reference The first byte is ignored, the remaining 3 bytes contain the RGB-components. StringToColor Only takes one argument of RGB. Invalid call. String representation of a color of "R,G,B" type or name of one of predefined Web-colors.- ColorToARGB Came from MT5 but alpha is ignored per #1.
SO, in mt4 we cant have semi-transparent lines/histograms, right?

Yes you can but not using indicator's buffer.

No, they will get the value of TRANSPARENT COLOR, but the value itself, is not obtained by BUFFER as transparent.

Can you write what your script does please?

is there a way to set semi-transparent color indicator's line?
i used this but none of these work:
......
SetIndexStyle(1, DRAW_HISTOGRAM , STYLE_SOLID, 1, StringToColor("0, 0,127,0") );
SetIndexStyle(1, DRAW_HISTOGRAM , STYLE_SOLID, 1, 0x00FF1234 );
SetIndexStyle(1, DRAW_HISTOGRAM , STYLE_SOLID, 1, ColorToARGB(clrRed, 0x55) );
SetIndexStyle(1, DRAW_HISTOGRAM , STYLE_SOLID, 1, ColorToARGB(clrRed, 0.55) );
