Working

Request to " https://www.nepalstock.com/api/authenticate/prove "
- Response consists of accessToken, refreshToken and salt[1...5] among other things.
- accessToken (which is 250 characters long) gets modified using some algorithm and salts; 5 characters are removed from it.
- Thus, we a new 'key' gets generated that is 245 characters long. This new key is what allows us to fetch data from the NEPSE API.
- The algorithm consists of 5 functions (cdx, rdx, bdx, ndx and mdx). They perform series of mathematical operations to generate some numbers.
- The original 'accessToken' is sliced up, based on the values of these 5 functions, and we end up with a new key.

Request to "https://www.nepalstock.com/api/nots/nepse-data/market-open"
- Response consist of "isOpen (Open/Close)", "asOf (date)" and an "id". This 'id' is later required to generate payload.
- Store the current day of the month using getDate() method.
- Then, a new integer gets generated as:
```
const generatedId = dummyData[marketStatus.id] + marketStatus.id + 2 * day;
    
    //Here,    
    //  dummyData = an array of  integers.
    //  marketStatus.id = 'id' from first /market-open.
    //  day = From second step
```
- New JSON object as {"id": generatedId}

Finally, request can be sent to "https://nepalstock.com.np/api/nots/security/[security_id]".
- Request method is "POST" and request body consist of JSON object from final step above.
- Authorization header is required which is "Salter " + [new_key] generated in Step 1.
- Some other headers are also required.
- Response consist of JSON object with info about requested security.
