Usage

Round information

All the information for the rounds is stored within the rounds collection in the database. A typical round looks like:

{
    "_id" : ObjectId("589a002d20692a659c7a5344"),
    "index" : 1,
    "prices" : {
            "BHARTIARTL" : 329,
            "HCLTECH" : 742.6,
            "HEROMOTOCO" : 3509,
            ...
    },
    "shares" : {
            "BHARTIARTL" : 100,
            "HCLTECH" : 100,
            "HEROMOTOCO" : 100,
            ...
    },
    "news" : [
            "Bharti Airtel slashes prepaid tariffs to compete with Jio.",
            "HCL felicitated at artificial intelligence summit in London.",
            "Hero MotoCorp to start production at Bangladesh plant next year.",
            ...
    ],
    "duration" : 120,
    "active" : false
}

Changing the information in this document will change the round info displayed to the user.

Choosing which round to run next

The app selects the round which has the active field set to true in the database. During normal round progression, the app normally updates the round with the next index by setting active: true. This behaviour can be overriden by manipulating the database, in case of re-running a round due to failuers.

Triggering the round start

The app uses console I/O instead of a separate admin panel to control the game. When all clients are ready, enter 2 at the admin console to start the currently active round. All clients will instantaneously start the round with the timer ticking and the round will end according the duration (in seconds) set in the round document within the collection.
