OptionChain from AngelOne

This information is correct on 18.02.2023, SmartAPI MAY change their API.

How to?

Settings

For proper working of the programm, firstly you should create settings.txt file in root of programm. Fill it with format of example below:

API_KEY:####;ID:####;PASSWORD:####;OTP_CODE:####

You may change the way of programm getting settings by changing InitSettings class in settings.py module.

Using

After making settings.txt file you`ll start main.py and every 3 minutes you will have updated .txt files of OPTIDX data in root of your programm. Each file have time of last update in first row, and contains all data provided about option.

Example of output data:

19:45:32
key:value/key:value/key:value/.../key:value
key:value/key:value/.../key:value/key:value
key:value/.../key:value/key:value/key:value

Change the output format or way

Change the format of data

To change the format of saved data you have to go into output_processor.py and change method parse_options_data_into_string. It gets python dictionary with format below:

{
   "CE":{
   }"PE":{
   }
}

CE is Call data; PE is Put data. Each have the dictionary of properties from Instrument list and WebSocket2.0 merged.

Instrument List - https://smartapi.angelbroking.com/docs/Instruments

WebSocket2.0 - https://smartapi.angelbroking.com/docs/WebSocket2

All the properties you can check in the SmartApi documentation in part about WebSocket2.0 (Snap Quote).

Change the way programm saving data

To change the way programm saving option data you have to go into output_processor.py and change method _push in it. This method is working with options_store_key_name dictionary where you have this structure:

{
   "BANKNIFTY":{
      "SYMBOL1":{
         "CE":{},
         "PE":{}
      }
      "SYMBOL2":{
         "CE":{},
         "PE":{}
      }
   }
   "NIFTY":{
      "SYMBOL1":{
         "CE":{},
         "PE":{}"
      }
      "SYMBOL2":{
         "CE":{},
         "PE":{}"
      }
   }
   ...
}
