Future bars - find Highest price and lowest price

[hbsopen]

Hi all - I gave up trying this. Essentially, what I am looking to do is:

- Take input = fwd_bars (let's say 11).

- let's say today is Jan 1st 2025.

- then looking forward for 11 bars (on a daily chart or for intra-day convert it to the appropriate number of bars equivalent for 11 days).

- find the highest price within the future bars and the lowest price. Subtract each from Jan 1st (meaning current bar) close and plot the two values.

I have tried Highest(high()) and used the Offset, but Highest() seems to be going forward to 11th day and getting the highest. Which is not what I want, because highest value could have occured in between.

I tried LookUp highest but this looks at the previous 11 bars!

I do understand that for the most recent 11 days there will not be a plot, which is fine.

declare lower;

input Look_fwd = 11;


#def hi = highest(high()[-look_fwd]);

def hi = LookUpHighest(length = -look_fwd);
def hi_diff = hi - close();

def low = Lowest(low()[-Look_fwd]);
def lo_diff = low - close();

plot hidiff = hi_diff;
plot lodiff = lo_diff;

How are future bars going to be plotted? Based on what basis? Can you provide further details?

def lo_diff = low - close();

plot hidiff = hi_diff;
plot lodiff = lo_diff;

EDIT
i didn't include any aggregation in this.
the chart has to be set to day, if you want to get data for days.

declare lower;

def na = double.nan;
def bn = BarNumber();

def lastbn = HighestAll(if IsNaN(close) then 0 else bn);
def lastbar = bn == lastbn;
input Look_fwd = 11;

#   these stop drawing a line  (Look_fwd)  bars from last bar
#def hi = highest(high[-(look_fwd-1)],look_fwd);
#def lo = lowest(low[-(look_fwd-1)],look_fwd);

#   these draw a line all the way to the last bar
def offset = Min(look_fwd - 1, lastbn - bn);
def hi = getvalue(Highest(high, Look_fwd), -offset);
def lo = getvalue(lowest(low, Look_fwd), -offset);

def hi_diff = hi - close();
def lo_diff = lo - close();

plot hidiff = hi_diff;
plot lodiff = lo_diff;

@halcyonguy --> Very many thanks. This is perfect, exactly what I was looking for. Could I please extend this thread with one more question - to educate myself with ThinkScript. You have used syntax Highest() and it worked .. however when I read the documentation 'Returns the highest value of data for the last length bars.' .. the way I understood is that it returns the value for the last length bar and not in between if highest or lowest occured sometime in between. But the way you have coded it works!

Highest() returns the highest value within the range desired, just as HighestAll() would return the highest value with the current Chart range history...
