Could someone make this code, plot the 25% and 50% extension of the previous day's range automatically

@Trading51 Per your request, here is a study that plots the 25% and 50% extension of the previous day's range. This is to be used on intraday charts only

Code: 
# Range Extension of Previous Day Range
# tomsk
# 1.11.2020

# This study plots the 25% and 50% extension of the previous day's range
# To be used on intraday charts only

declare hide_on_daily;

def CurrentDay = GetDay() == GetLastDay();
def prevHigh = if CurrentDay then high(period = AggregationPeriod.Day)[1] else Double.NaN;
def prevLow = if CurrentDay then low(period = AggregationPeriod.Day)[1] else Double.NaN;
def prevRange = if CurrentDay then prevHigh - prevLow else Double.NaN;

plot UExt25 = prevHigh + (prevRange * 0.25);
plot UExt50 = prevHigh + (prevRange * 0.50);
plot LExt25 = prevLow  - (prevRange * 0.25);
plot LExt50 = prevLow  - (prevRange * 0.50);

UExt25.SetDefaultColor(Color.Cyan);
UExt50.SetDefaultColor(Color.Pink);
LExt25.SetDefaultColor(Color.White);
LExt50.SetDefaultColor(Color.Green);

perfect thank you, is it possible to add the previous day's midpoint?

Here is version 1.1 of the Range Extension study with the previous day's midpoint plotted as dotted yellow line to make it distinct from the other plots

Code: 
# Range Extension of Previous Day Range
# tomsk
# 1.11.2020

# V1.0 - 01.11.2020 - tomsk - Range Extension of Previous Day Range
# V1.1 - 01.11.2020 - tomsk - Added plot of previous day range midpoint

# This study plots the 25% and 50% extension of the previous day's range
# To be used on intraday charts only

declare hide_on_daily;

def CurrentDay = GetDay() == GetLastDay();
def prevHigh = if CurrentDay then high(period = AggregationPeriod.Day)[1] else Double.NaN;
def prevLow = if CurrentDay then low(period = AggregationPeriod.Day)[1] else Double.NaN;
def prevRange = if CurrentDay then prevHigh - prevLow else Double.NaN;

plot UExt25 = prevHigh + (prevRange * 0.25);
plot UExt50 = prevHigh + (prevRange * 0.50);
plot LExt25 = prevLow  - (prevRange * 0.25);
plot LExt50 = prevLow  - (prevRange * 0.50);
plot PrevMid = prevLow + (prevRange / 2);

UExt25.SetDefaultColor(Color.Cyan);
UExt50.SetDefaultColor(Color.Pink);
LExt25.SetDefaultColor(Color.White);
LExt50.SetDefaultColor(Color.Green);

PrevMid.SetDefaultColor(Color.Yellow);
PrevMid.SetStyle(Curve.Short_Dash);
PrevMid.SetLineWeight(3);

perfect, if I wanted to use that on a higher time frame like the weekly, what would I have to adjust in the code would it be simple?

@Trading51 OK, here is a study that plots the 25% and 50% extension of the previous week's range. Remember this is to be used on intraday charts only

Code: 
# Range Extension of Previous Week Range
# tomsk
# 1.11.2020

# This study plots the 25% and 50% extension of the previous week's range
# To be used on intraday charts only

declare hide_on_daily;

def CurrentDay = GetDay() == GetLastDay();
def prevHigh = if CurrentDay then high(period = AggregationPeriod.Week)[1] else Double.NaN;
def prevLow = if CurrentDay then low(period = AggregationPeriod.Week)[1] else Double.NaN;
def prevRange = if CurrentDay then prevHigh - prevLow else Double.NaN;

plot UExt25 = prevHigh + (prevRange * 0.25);
plot UExt50 = prevHigh + (prevRange * 0.50);
plot LExt25 = prevLow  - (prevRange * 0.25);
plot LExt50 = prevLow  - (prevRange * 0.50);
plot PrevMid = prevLow + (prevRange / 2);

UExt25.SetDefaultColor(Color.Cyan);
UExt50.SetDefaultColor(Color.Pink);
LExt25.SetDefaultColor(Color.White);
LExt50.SetDefaultColor(Color.Green);

PrevMid.SetDefaultColor(Color.Yellow);
PrevMid.SetStyle(Curve.Short_Dash);
PrevMid.SetLineWeight(3);

I gave it a shot to add a label but I can tell I'm way off, this is what I have (addchartBubble price location" = PrevHigh, text = "+25% Ext " color = Color.White); Zero coding ability :)

the labels you added are fine, I meant could you add the previous high and low lines with labels that go with the ones on the charts? sorry for the confusion :)

@Trading51 Per your enhanced request, I have made the changes you requested in the revised version 1.3. Additionally to give you an added option, I have included an input "displayLabel" that you can set to "no" in the user interface should you no longer wish to see the labels. Here then is the revised code. Hope this helps

While the intraday high/low two days ago can easily be determined, logistically balancing the display between the previous day and the previous previous day is going to induce a layer of complexity. My suggestion is to just keep things simple and stick with the last version posted. If you still wish to reference the high/lows 2 days ago, all you need is to index it as follows. Personally I see no value add there.

Code: 
def prevPrevHigh = if CurrentDay then high(period = AggregationPeriod.Day)[2] else Double.NaN;
def prevPrevLow = if CurrentDay then low(period = AggregationPeriod.Day)[2] else Double.NaN;
