Auto Fibo on the previous day

[thomasmore]

Dear all,
I found an indi I'd like to use, but it misses some of my favoured input possibilities. Would someone be so kind to modify this?
User inputs should contain:
1: fib levels to show
2: line colour
3: line style
4: line start at previous day open
5: lines extend beyond actual day by xx

Thanks for your time and effort,
Ludo
