Weekly break out Fib extension script

[imran79]

Hello, I am a new member here. Can anyone write me a script for a weekly high and low breakout of the last weekly candle to set targets of 1.27, 0.618, 200, and 261.7 fib ext.? If I can get an alert that a new high was made, then I can follow the trade from there.
I appreciate it.

Thank you.
Imran

is this what you are looking for ?
find high/low of previous week and plot lines on current week. ( dashed )
then using the range between the lines, times a factor, and set as 100% , draw lines at fib levels.
. 0.618, 1.27, 2.00, 2.617
sound an alert if a line is crossed.
