On the Option Chain - DhanHQ Ver 2.0 / API Document, I see that we have got the volume information in Day volume for Option Instrument. How often is this updated? like what is the average lagtime to this value when fetched over api?
Also, please provide the turnover value information as well, akin to exchange providing this information already.
step 2.
visit this url , its a big json so will take time but if you get resource not found page, just do step 1 again and then do step 2. you will have to get a pretty json response (may be there is a prettifier in browser extension itself).
look for turnover (case-insensitive search in metadata for a given strike type and also tradeInfo section for the option instrument)
this helps with adding context and meaning to other information that is already available thus far via the current api req/response. this provides usability to the liquidity
