Line from a Bar to next few bars (after a condition met)

I would like to get a horizontal line when price cross yesterday high plus 5 points (condition ) from that bar to next few bars . Tried many ways .. but failed ..Appreciate any one time and help.


I think i figured it .

yDayH = 	TimeFrameGetPrice("H", inDaily, -1);	   			// yesterdays high

yhabove= C>yDayH ;

yhline=IIf(yhabove,yDayH+10,Null); // 10 points above yesterday high 
Plot(yhline,"",colorYellow, styleThick );
