Create a horizontal drawing, then remove it once price hits it

Hi, I use Friday's high/low as the opening range for the next week. Based off the Friday's high/low I create extension lines (ie. a percent times the range above and below). I'm interested in automating it so that once price hits one of these levels they vanish from the charts. This will keep extensions on chart from previous weeks that haven't been hit yet. Does anyone know of a way to do this?

it can be done. there can't be unlimited lines plotted, but several can be drawn.

i came across this post a couple weeks ago, and thought it might be possible.
after many hours of trying, i have this.
the original post didn't mention how many weeks back to look at. i had to copy some sections of code for each day, so i thought 6 days...

While it's true that this is not possible (as stated by @rad14733), there is a workaround.

Step 1: Hover to the price level of your choice > right-click > "Create alert..."

Step 2: In the "Create Alert on Price" screen, configure if you want to get notified for price crossing above or below the particular price.

Step 3: Hit Create.

Step 4: Now, you should see the yellow horizontal alert line on your chart. Once the stock price hits the condition you set in Step 2, the line will disappear.

I hope that helps.

Thank you @BenTen for the detailed reply. I use alerts extensively, however I need it done as a script because I have a large watchlist with automated signals and I need to be able to flip through them quickly

# show lines from previous day levels, except if price crosses a level.

# pick a desired day of week, monday, tues,....
# pick how many weeks to look at, 1 to 6
# pick how to show lines if price crosses them: invisible, dashes, solid

# find the high and low for each desired day
# draw lines from high and low levels, from each desired day of the week
# check if price crossess a high or low level, from one of the previous selected days of the week
# change the line if price crosses it, solid, dashed, or invisible
# show bubbles on right side of chart, that identify the lines

on the first bar of the desired days, it runs a loop to check if price crossed a line.

at the end of the code are code samples, some that worked, some that didn't.
some for testing, displaying variables.
it is possible to use an if-then to choose a PaintingStrategy, but when zoomed out, a dash line looks solid, so i didn't use it.
i couldn't get SetStyle(Curve. to work with an if-then, so i ended up using a separate code line for each line.
