Open and Last Price Lines

[IHopeToLearn]

Hi guys,
I found these two scripts which I combined and altered. What I am missing and would like is to show the difference from the Opening Stock Price to the Last price in Percentage and Price displayed on both lines. Showing also if it went down or up using + or - symbols.

Also since I'm asking if possible, in Green for Up and Red for Down, and finally, the ability to see the previous days if wanted. Thanks

See screenshot here:

Here's the code:
#This is where I found the code for the opening price, thanks
#https://usethinkscript.com/threads/current-price-line-indicator-for-thinkorswim.614/post-8400

#Plots a Horizontal Line for the opening price
declare upper;

def agg = AggregationPeriod.DAY;
plot OpenLine = open(period = agg);

OpenLine.setpaintingStrategy(paintingStrategy.LINE);
OpenLine.setlineWeight(1);
OpenLine.setdefaultColor(color.white);
OpenLine.hideBubble();

#This is where I found the below code, and a thank you for this
# https://usethinkscript.com/threads/current-price-line-indicator-for-thinkorswim.614/post-8400

#Plots a Horizontal Line that follows the price value selected
input price=close;
input offset=0;
input length = 300;

def sma = SimpleMovingAvg(price, 1, length);
rec line = if IsNaN(sma) then line[1] else sma[offset];
plot priceline=if isnan(sma) then line else double.nan;
priceline.setpaintingStrategy(paintingStrategy.POINTS);
priceline.setlineWeight(1);
priceline.setdefaultColor(color.white);
priceline.hideBubble();

the 2 links you included, are the same.
but you did provide the code so not a big deal.


that code for a price at the close, only works if there are more than 300 bars on the chart.
if there are less, then the line is drawn at 0.

#Plots a Horizontal Line that follows the price value selected
input length = 300;

this is a better code for drawing a priceline

it isn't clear what prices you want to compare. opening stock price? that could be the open price on every bar or the open at the start of a days regular trading hours.


if you want the option to also see the previous days price levels, then you don't want lines that extend across the whole chart. you want 2 horizontal lines for open and close, on each day.

# open_to_close_per_0

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

def agg = AggregationPeriod.DAY;
def dayopn = open(period = agg);
def daycls = close(period = agg);

def day_updwn = if daycls > dayopn then 1 else if daycls < dayopn then -1 else 0;

# is last day the current day
def istoday = if GetLastDay() == GetDay() then 1 else 0;
input show_only_today = yes;
# draw only on current day  yes/no
def days_en = if show_only_today then istoday else 1;

plot OpenLine = if days_en then dayopn else na;
OpenLine.setpaintingStrategy(paintingStrategy.horizontal);
OpenLine.setdefaultColor(color.white);
OpenLine.setlineWeight(1);
#OpenLine.hideBubble();

plot closeline = if days_en then daycls else na;
closeLine.setpaintingStrategy(paintingStrategy.horizontal);
#closeLine.setdefaultColor(color.cyan);
closeLine.setlineWeight(1);
#closeLine.hideBubble();
closeline.AssignValueColor(if day_updwn > 0 then color.green else if day_updwn < 0 then color.red else color.gray);

# % bubble
def per = round(100 * (daycls - dayopn)/ dayopn, 1);

def n = 2;
def x = (!isnan(close[n]) and isnan(close[n-1]));
addchartbubble(x, closeline[n], per[n] + "%", color.yellow, (if day_updwn[n] > 0 then yes else no));

# shading
input shading_between_lines = yes;
def cldtop = if shading_between_lines then closeline else na;
def cldbot = openline;
addcloud( cldtop, cldbot, color.green, color.red);
#

show_only_today = no
shading_between_lines = yes
