Need mt4 script draw a fibo

I looking for a script .

Is it possible do to that ?

This script will draw a fibo on the chart .

by defaut this fibo has 4 level , 

difference between each level is in pip (  20 pip , 30 pip , 40 pip  by default)

example : 4 level

first line level 0 , 

second line level = ( 0 +20pip) = 20 pip

third line = ( 0 + 20 pip + 30 pip ) = 50 pip

fourth line ( 0 + 20 pip + 30 pip + 40 pip ) = 90 pip

like this example , with 4 level , i need only 3 number 20,30,40, to draw the four level of the fibo

the lenght is in days ( 1 day by default ) ( no ray please )

color yellow by default, 

thickness medium by default

( numbers of  level ,difference between level , lenght , color , thickness should be costumize when i drop the script )

the localisation of the fibo is where i drop the script

need the mq4 file
