@Gloriafilamino , Thanks for the replied thread. Though there was no ready made answer in it but after lot of trial and error I was able to resolve my own query. And here is the code-

highOfDay = TimeFrameGetPrice( "H", inDaily );
lowOfDay = TimeFrameGetPrice( "L", inDaily );

//x coordinate is actuall a bar number , just count bar number from left to right and deduct 1 to get desired line //from x coordinate. y is off course price.

x0=91;
y0=9963.8;
x1=819;
y1=10533.5;

Line = LineArray( x0, y0, x1, y1, 2 );

Plot( Line, "Trend line", colorRed );
