Projection indicator high and low

[Drmoh1800]

I have a new idea where we would look back at 20 bars for examples to analyze the highs and lows, measure the difference, and then project equal potential moves both upward and downward based on this range. I'm not sure if this is feasible, though.or not . Thanks in advance .
Lets make it certain time window 9 to 9:30 can be adjusted if needed . Projection is good for end of the day .

your description is too vague

i made some guesses and made this

go back 2 bars,
then look back 20 bars and find the highest and lowest
calc the difference. apply multiplier to this
find the center of current bar
center the hi-lo range around the current bar
draw lines from last bar


how many bars back from current bar to start looking for highs and lows
input set_back = 2;

over how many bars to look for a highest and lowest
input bars_back = 20;

a multiplier applied to highest-lowest range
input range_factor = 1.0;

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

def lastbn = HighestAll(If(IsNaN(close), 0, bn));
def lastbar = if (bn == lastbn) then 1 else 0;

#def lastbar = !isnan(close[0]) and isnan(close[-1]);
#def last_close = highestall(if lastbar then close else 0);

input set_back = 2;
input bars_back = 20;
input range_factor = 1.0;

def hi = Highest(high[set_back], bars_back);
def lo = Lowest(low[set_back], bars_back);
def rng = range_factor * (hi-lo);

def mid = (high+low)/2;

# save line data on last bar
def hi2 = if bn == 1 then 0
# else if !isnan(close) and isnan(close) then mid + rng/2
 else if lastbar then mid + rng/2
 else hi2[1];

def lo2 = if bn == 1 then 0
# else if !isnan(close) and isnan(close) then mid - rng/2
 else if lastbar then mid - rng/2
 else lo2[1];

#plot zhi = if hi2 > 0 then hi2 else na;
#plot zlo = if lo2 > 0 then lo2 else na;
plot zhi = if (bn >= (lastbn-0)) and (bn <= (lastbn+2)) then hi2 else na;
plot zlo = if (bn >= (lastbn-0)) and (bn <= (lastbn+2)) then lo2 else na;
zhi.setdefaultcolor(color.cyan);
zlo.setdefaultcolor(color.cyan);
