Simple CAS Prediction Method (Before 3:30 PM) - Sensex, Nifty, Bank Nifty

 

Simple CAS Prediction Method (Before 3:30 PM)

Purpose

After 3:15 PM, the Sensex cash chart stops moving because of the Closing Auction Session (CAS).

To estimate where Sensex is moving, watch the ATM or 1 ITM Call Option.

---

Step 1 – At 3:15 PM

Example:

• Sensex = 78,785
• ITM Strike = 78,700 CE
• Option LTP = 365

Calculate:

Intrinsic Value

= 78,785 − 78,700

= 85

Extrinsic Value

= 365 − 85

= 280

Remember only one number: 280 (Extrinsic).

---

Step 2 – During CAS (3:16–3:30 PM)

Watch only the option price.

Formula:

Estimated Sensex

= Strike + Current Option Price − 280

---

Example 1

Option = 390

Sensex

= 78,700 + 390 − 280

= 78,810

---

Example 2

Option = 425

Sensex

= 78,700 + 425 − 280

= 78,845

---

Example 3

Option = 500

Sensex

= 78,700 + 500 − 280

= 78,920

---

Quick Rule

If the option price rises by:

+20 points → Sensex is approximately +20 points

+50 points → Sensex is approximately +50 points

+100 points → Sensex is approximately +100 points

As long as the extrinsic value stays nearly the same, every 1-point move in the option roughly corresponds to a 1-point move in the index.

---

Easy Memory Trick

At 3:15 PM:

✔ Note the Sensex level.

✔ Note the option LTP.

✔ Calculate and remember only the Extrinsic Value.

From 3:16 PM to 3:30 PM:

Estimated Sensex = Strike + Option LTP − Extrinsic

---

Example Summary

Time	Option LTP	Estimated Sensex
3:15	365	78,785
3:16	390	78,810
3:17	425	78,845
3:18	450	78,870
3:20	500	78,920

---

Important Note

This method estimates the current Sensex value during CAS. It does not predict the final closing price by itself. The final CAS close depends on the buy and sell orders matched in the closing auction, so the actual close can still differ slightly from the estimate.

Apache2 disable directory listing

Step 1: The best way to do this is disable it with webserver apache2. In my Ubuntu 14.X - open /etc/apache2/apache2.conf change from

Sample

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to

<Directory /var/www/>

Ubuntu - Apache2 403 forbidden after changing the directory path apache2.conf Solution

 Step 1 

Always better to create a folder under your home/user folder.

for ex:

    mkdir /home/drvijay/html

    cd /home/drvijay/

    chmod -R 775 html/

    chown drvijay:drvijay html/

 

Step 2

> sudo nano /etc/apache2/sites-available/000-default.conf

#Comment the older root path and add yours

#       DocumentRoot /var/www/html

        DocumentRoot /home/drvijay/html 

Step 3

> gedit /etc/apache2/apache2.conf

#add your block and comment the /var/www/html block

How to install Gnome Extensions

 Extract the downloaded file. Copy the folder to ~/.local/share/gnome-shell/extensions directory. Go to your Home directory and press Crl+H to show hidden folders. Locate .local folder here and from there, you can find your path till extensions directory. 

Once you have the files copied in the correct directory, go inside it and open metadata.json file. Look for the value of uuid. 

Make sure that the name of the extension’s folder is same as the value of uuid in the metadata.json file. If not, rename the directory to the value of this uuid.

Name of extension folder should be the same as uuid

Almost there! Now restart GNOME Shell. Press Alt+F2 and enter r to restart GNOME Shell.

Restart GNOME Shell

Restart GNOME Tweaks tool as well. You should see the manually installed GNOME extension in the Tweak tool now. You can configure or enable the newly installed extension here.

And that’s all you need to know about installing GNOME Shell Extensions.

Remove GNOME Shell Extensions

It is totally understandable that you might want to remove an installed GNOME Shell Extension.

If you installed it via a web browser, you can go to the installed extensions section on GNOME website and remove it from there (as shown in an earlier picture).

If you installed it manually, you can remove it by deleting the extension files from ~/.local/share/gnome-shell/extensions directory.

Product Idea : Universal Hub for Patient Medical Records – UHPMR

 Idealist: D.R. Vijaykumar
Draft: Version 0.1

Why?
So far, Healthcare industry has been slow to adapt to a technology. Thus, the current healthcare ecosystem comprises in information systems that lack data security, interoperability, standardisation, sharing, collaborating and trust.

Who will do?
    This should avoid if a Single system handles the Patient Medical Records universally to storing all his Records electronically into a CENTRALIZED ARSENAL “CR” like Youtube for videos, which are imperative for seamless health information exchange to any System himself has a talking/collaborating facility and completely handle by Patient only only only.

To Whom?
Let’s begin with a Story!
A boy named Kumar from a South Indian middle class family, he lived with his parents. His father used to collect all his Son used items, photos, videos, dresses and all activities at each and every stage including his son’s school bills rather than medical records as a part of memories, When I asked his father, Why are you keeping school bills?, He replied with caution, School bills may useful if the school says, you didn’t pay your son tuition fees and he pointed out with smile, Not only to me!, most of the families are doing the same. Days went and I started watching his family activities, noted one thing and realize they didn’t keep the medical records as a part of activities.
Every time he took his son Mr. Kumar to the hospital whether Minor/Major problems. They will go like the first time visitor, because he doesn’t keep the medical records in their hand. He gave less important to his son medical records until his son diagnosed with unknown disease. A good doctor named Vijay, stepped into his son problem to analyse when it starts, initially he don’t have clue and faced many problems, Such as
•    When he faced similar kind of problems.
•    Which Physician or Hospital he visits.
•    What Doctors prescribed.
•    What course he went.
•    After what other medical issues faced in-between.
•    Is this a genetically inherited.  
•    Even well educated person will ignore the prescriptions prescribed by doctors on minor problems like cold, cough, headache, rashes, but they don’t aware even a headache is the symptoms for brain cancer and it can route to death.
At last a Good Doctor finds the reason that it is a “genetically inherited” which he got it from his own Mother where she passed away when he was kid. Unfortunately his son died, I was deeply saddened and want to know what happened to him, so I can build Software to overcome these situations between patient and doctor. So I personally contact the Good Doctor and discussed, here are the points he furnished with emotions.
As I am a Doctor, My duty is to cure all patients whoever visiting to our hospital. So we created a healthy ecosystem to give natural immune power to patients. Also we build Software where we can store all the Patient information’s and his visiting histories. But WE LAGGING AND LACKING to get all information’s about Patients. Even though Healthcare industry has grown far, still I am facing a problem, such as.
•    Only I can access the patient information which is stored in my Hospital Database.
#. But that is not sufficient to start prescribing a medicines to patient, because we cannot assure the patient is always visiting our hospital only.

•    Now Hospital Software systems are improved and its starts collaborating between Hospitals to share the Patient Medical Information based on the Patient request and consent approval.
#. But anytime the hospital himself can withdraw the sharing features, because it is not legalize yet.
#. They cannot serve, due to technical failure and it will impact when patient is in urgent.
#. Any changes from either a side will impact the smooth transition of PMR “Patient Medical Record”.
•    Even though Technology has helped the healthcare ecosystem to optimise these complex workflows by connecting the various stakeholders and providing real-time information that helps in delivering enhanced patient care.
#. But still all above problem exists.



What I “CR” do?    
    CENTRALIZED ARSENAL is the only solution where a Patient can keep his/her Medical Records electronically at one place.
•    Patients can upload his PMR at any time anywhere at any point and order it into right folder.
•    Patient can re-order the records at his/her convenient.
•    Global Internal SEO will make sure the patient can filter or search the records at any point.
•    Hospital can push the record via multiple channels to this centralized arsenal after patient consent.
•    No expiry for the records stored inside centralized arsenal.
•    Patient can directly share his MR “Medical Record” to doctor/hospital who installed the same UHPMR app or via web browsers.
•    It will be secure and not allowing Doctor to download.
•    Patient only can download or delete the PMR on his/her records.
•    Patient itself can set the expiry DT while sharing to doctor app.
•    Patient can revert at any time and no need to wait until the expiry DT set previously.
