# Need help extending lines on Ichimoku Cloud

#### Intriquality

##### New member
Hello!

I'm trying to make an Ichimoku Cloud (SPAN B) support/resistance line drawer, but I'm unsure how to extend the lines to the right.

The indicator looks for flat areas (flat over at least a 20-bar period) on the SPAN B portion of the Ichimoku Cloud and draws the line there.

My amazing, unparalleled display of scripting prowess (sarcasm) is displayed below.

This is what the indicator is trying to do:

This is what I have it looking like so far:

This is what I'm trying to turn it into:

I also have a secondary, less important issue of this indicator not working on any timeframe higher than the 1D. Not sure why.

Here's the script:

declare upper;
def kijun_period = 26;

def dP = aggregationPeriod.DAY;
def wP = aggregationPeriod.WEEK;
def mP = aggregationPeriod.MONTH;

def dKijun = (Highest(high (period=dP), kijun_period) + Lowest(low (period=dP), kijun_period)) / 2;
def span_B = (Highest(high (period=dP)[kijun_period], 2 * kijun_period) + Lowest(low (period=dP)[kijun_period], 2 * kijun_period)) / 2;

def dailyCloudLineB = if span_B[-16] == span_B[-17] and
span_B[-17] == span_B[-18] and
span_B[-18] == span_B[-19] and
span_B[-19] == span_B[-20] and

span_B[-23] == span_B[-24] and
span_B[-24] == span_B[-25] and
span_B[-25] == span_B[-26]
then span_B[-26] else double.NAN;

plot daily = dailyCloudLineB[16];

#----------------------------WEEKLY CLOUDLINES
def wKijun = (Highest(high (period=wP), kijun_period) + Lowest(low (period=wP), kijun_period)) / 2;
def wSpan_B = (Highest(high (period=wP)[kijun_period], 2 * kijun_period) + Lowest(low (period=wP)[kijun_period], 2 * kijun_period)) / 2;

def weeklyCloudLineB = if wSpan_B[-16] == wSpan_B[-17] and

wSpan_B[-25] == wSpan_B[-26]
then wSpan_B[-26] else double.NAN;

plot weekly = weeklyCloudLineB[16];

#----------------------------MONTHLY CLOUDLINES
def mKijun = (Highest(high (period=mP), kijun_period) + Lowest(low (period=mP), kijun_period)) / 2;
def mSpan_B = (Highest(high (period=mP)[kijun_period], 2 * kijun_period) + Lowest(low (period=mP)[kijun_period], 2 * kijun_period)) / 2;

def monthlyCloudLineB = if mSpan_B[-20] == mSpan_B[-21] and

then mSpan_B[-26] else double.NAN;

Solution
Hello!

I'm trying to make an Ichimoku Cloud (SPAN B) support/resistance line drawer, but I'm unsure how to extend the lines to the right.

The indicator looks for flat areas (flat over at least a 20-bar period) on the SPAN B portion of the Ichimoku Cloud and draws the line there.

Here's the script:

Here are 3 versions, one for each timeframe.
Each has a minimum flat line length that you can change at the input screen.
The lines will plot from the point when the minimum length is met to the right edge. This was done with the script() function, as a plot is necessary for each line when the condition is met. I
This has 4 plots for each version, with bubbles. You can create more using the logic of he 4 lines.

You can load all 3 versions on a Daily chart.
The reason you did not get any plots when going to timeframes higher than a Daily is because your loaded studies can not include any lower timeframes than the chart timeframe. So the Daily chart being loaded on a Weekly or Monthly chart will cause none of the scripts to plot.

The image shows all 3 versions in the upper pane. The middle and lower have the individual Weekly and Monthly loaded.

You weee very creative and did nice work in your scrript. These scripts use a little different method. Hope this helps.

Code:

def count = if B != B[1] then 0 else if B == B[-1] or B == B[1] then count[1] + 1 else count[1];
def basis = if count == dlength and B then basis[1] + 1 else basis[1];
def cond  = HighestAll(basis) - basis + 1;

This is AMAZING. Thank you! I've been playing with it and it is VERY close to what I am looking for. It's a huge improvement from what I made - being able to see the lines extended across the chart.

I have noticed a couple of things that I need to try and figure out:

-The indicator doesn't seem to work if you use it on a timeframe that displays a timeframe longer than where the ichimoku cloud first started. For example, if you look at the ticker DRIP and display a timeframe of WEEKLY / 10 YEARS, then the indicator simply won't display.

-The indicator doesn't seem to plot the "forward-looking" portion of the Ichimoku cloud. Areas like the one in the image below don't seem to be accounted for in the code.

-This indicator doesn't seem to have much use on intraday timeframes like the 5M, because apparently, you need to have the timeframe showing as far back as the indicator is attempting to draw the line (so if you want to see a weekly line that is based on a datapoint from 4 years ago, you would need 4 years of 5M charts, which sadly ToS doesn't let you do. I'm not sure you'd want to do that anyway, since loading 4 years of 5M charts would make it super sluggish.

Not sure how difficult it would be to fix the first two issues. All that being said, this is still a SUPER nice tool for the daily chart. Without any changes, I already love the capability of this indicator. Hopefully, some improved iterations come out of this in the future!

Thanks again for your hard work!
