I’ve found this Japanese blog that mentions scripts which allows users to assign keyboard shortcuts for trend lines, horizontal lines, Fibo, etc, however, there seems to be a bug in the code; it won’t compile.

can someone help me with this ?

FOR Trend Lines.

#import "user32.dll"
int GetParent(int);
#import
#include
void start()
{
int hwnd = GetParent(GetParent(GetParent(WindowHandle(Symbol(),Period()))));
PostMessageA(hwnd, WM_COMMAND,33257,0);
}

Horizontal – change the last numbers to 33244,0
CrossHair – change the last numbers to 33233,0
Fibo. Ret. – change the last numbers to33237,0

Thanks!
