10 Day Lookback Marker

Hi,
Can someone help me with some code for ToS on a 10 day look back marker? The 10 day isn't necessarily key, I just want a simple script that puts a dot or an arrow on top of a candle 10 days from the current candle in the past. This sounds awfully simple but I can't code to save my life.

I'd appreciate any help on this.

Thanks
Charlie.

i know this post is old, but i had the code in my head from another project, and i thought it might be of use.

enter a number for days back to look at.
whatever the current bar of day is, that same bar, on the desired day, will be identified with an arrow and a rectangle outline.

2 labels, list the day offset and the desired bar of day number.

2 labels, list the day offset and the desired bar of day number.
if there aren't enough days on the chart, a cyan label message appears.

# desired day in the past
def dayx = if days_back == revdaycnt then 1 else 0;

addlabel(!dayback_ok, ">>>> chart doesn't have " + days_back + " days <<<<", color.cyan);
