Snapquote Data

Snapquote data refers to a snapshot or instantaneous view of essential market data for a specific financial instrument at a particular moment in time. It typically includes key information such as the instrument's last traded price, bid and ask prices, trading volume, and possibly other relevant metrics. This data is crucial for real-time monitoring of market conditions and can help traders react swiftly to changes in prices and trading activity.

To get the snapquote data, the first step is to subscribe the instrument for which we need the data.

Below is the list of exchange codes which will be required while subscribing to a particular instrument.

exchange_code = {
    "NSE" : 1,
    "NFO" : 2,
    "CDS" : 3,
    "MCX" : 4,
    "BSE" : 6,
    "BFO" : 7
}

Subscribe instruments to get market data

You can subscribe or unsubscribe single or multiple instruments to get market data.

To subscribe only one instrument.

snapquotedata_payload= {'exchangeCode': 1, 'instrumentToken': 'token'}
response = pocket_ws.subscribe_snapquote_data(snapquotedata_payload)

To subscribe multiple instrument.

multiple_snapquotedata_payload = {}
response = pocket_ws.subscribe_multiple_snapquote_data(snapquotedata_payload)

Example

snapquotedata_payload= {'exchangeCode': 1, 'instrumentToken': 1333}
response = pocket_ws.subscribe_snapquote_data(snapquotedata_payload)
