Simplified Excel sheet for Stock Option traders to fetch and analyze NSE Stock Option Chain Data for both Calls and Puts. This Excel sheet fetches the live NSE Stock Option Chain data such as OI and Price at different strike prices specifically few Strike Price ranges near to ATM in Excel sheet.               This is coded in VBA and can fetch the following data at a given Strike Price, for both Calls (CE) and Puts (PE) and at different Expiry Dates. > Open Interest (OI) > Change in Open Interest (in %), > Last Traded Price for NSE Stock option (in INR) > Change in Last Traded Price (%)   It narrows down and fetches few selective Strike Price ranges only at Out of Money (OTM) near to ATM (At the Money) and not fetches from deep far Out of Money Strike Price data. So, it gives a simplified view on OI and Price changes.   How to use? 1. Select the Stock Symbol. 2. Then Select the Expiry Date an

This VESTA tutorial demonstrates the following: 1. How to download and analyze .cif (Crystallographic Information File) from Open Crystallographic Database using VESTA program? 2. How to simulate X-ray diffraction patterns in VESTA from the crystal unit cell volume? 3. How to interpret and view the lattice planes, d-spacing in a 3-dimensional way? 4. How to perform matrix transformation correctly, in {hkl} Miller indices planes? 5. Matrix transformation by using simple matrix multiplication followed by the location of the new Miller plane after the transformation.   6. Identification of Miller {hkl} planes from crystal dimensions and XRD patterns. 7. Correlates the unit cell dimensions, d-spacing and 2-theta (2θ) values.

Zotero Tutorial - Automating References / Bibliography for Writing Research Paper, Book and PhD Thesis in MS Word. For academicians, researchers and Ph.D. scholars, inserting & editing the References or  Bibliography manually to a specific Journal Reference style is tedious & time consuming, while writing a research paper or a book or a PhD thesis or manuscripts with MS Word processor. With Zotero (freeware) in Word this boring and cumbersome referencing  process can be automated easily and quickly. This video tutorial demonstrates how to insert / modify the references fetched from webpages in word using Zotero.

Full width at half maximum (FWHM) for a curve is used in many scientific experimental data analyses. For instance, in X–ray diffraction analysis of crystal data, it is used to find the grain size from the curve. FWHM is the width of the curve or simply the difference in the corresponding two ‘x’ data values at y max /2. y max refers the highest value of ‘y’ or ‘y’ value for the maximum peak height.   Example Set of ‘x’ and ‘y’ data and the corresponding curve is given below: (View this Page for back reference.)     x      y 0.0    0.000 0.1    0.146 0.2    0.284 0.3    0.414 0.4    0.536 0.5    0.650 0.6    0.756 0.7    0.854 0.8    0.944 0.9    1.026 1.0    1.100 1.1    1.166 1.2    1.224 1.3    1.274 1.4    1.316 1.5    1.350 1.6    1.376 1.7    1.394 1.8    1.404 1.9    1.406 2.0    1.400 2.1    1.386 2.2    1.364 2.3    1.334 2.4    1.296 2.5    1.250 2.6    1.196 2.7    1.134 2.8    1.064 2.9

What is Haircut in stock market? Haircut is the amount of margin money deducted while pledging the Equites/ Mutual Funds / Bonds for trading. A haircut value of 13% means that, if a share worth of Rs 100 is pledged for trading, then Rs. 13 will be deducted and Rs. 87 will be given as collateral margin for trading. It is based on previous closing price.   This program is used to identify the real worth or money value of an equity / share / sovereign Gold Bonds (SGB) at the selected date.   This program fetches the historical Haircut data (%) and Price of Equities listed in NSE, India at the specified date.   Enter the Date (in the format: dd-mm-yyyy) to get Haircut data for equities listed in NSE. It lists the haircut value (%) and the respective price of the equity at the given date.   Enter the symbol for equity listed in NSE. For example, Infosys should be entered as INFY.   Note: If the date falls on holiday, no results will be displaye
