Using the Angel one Smart API, can I fetch/Get the live fluctuating Indicative Equilibrium Price during the Closing Auction Session(CAS) from 3:20 - 3:30 PM?

i want to fetch these elements:

• Indicative Equilbrium Price(IEP) as per live fluctuating demand and supply
• volume during the CAS as per live fluctuating demand and supply
• reference price during CAS

if yes, please tell me it could be fetched using "Web Socket" or "Endpoint" or BOTH?

and please also share the "IEP" element name as like:

---Python
emit({
        "type": "tick",
        "symbol": sym,
        "exchange": ex,
        "ltp": safe_number(row.get("ltp")),
        "open": safe_number(row.get("open")),
        "high": safe_number(row.get("high")),
        "low": safe_number(row.get("low")),
        "close": safe_number(row.get("close")),
        "volume": safe_int(row.get("tradeVolume") or row.get("volume"))
)}
---Node.js
  const open = Number(quote.ohlc?.open || 0);
  const high = Number(quote.ohlc?.high || 0);
  const low = Number(quote.ohlc?.low || 0);
  const close = Number(quote.ohlc?.close || 0);
  const ltp = Number(quote.last_price || 0);
  const volume = Number(quote.volume || 0);

as like the open, high, close, low, ltp, there must be something by which i can fetch the fluctuating realtime "Indicative Equilibrium Price" based on demand and supply?

just i want to know the element name, which is correct

i tried for getting the referencePrice and IEP and total imbalances but, i found successfully only the reference price

const referencePrice = optionalNumber(
    quote.referenceLimitPrice, quote.reference_limit_price, quote.reference_price, quote.referencePrice, quote.ref_price
  ); // i got success in fetching the reference price only
  const indicativeClose = optionalNumber(
    quote.indicativeClose, quote.indicative_close, quote.indicative_price, quote.equilibriumPrice, quote.iep
  ); // no data received using these elements
  const totalImbalance = optionalNumber(
    quote.totalImbalance, quote.total_imbalance, quote.imbalanceQuantity, quote.imbalance_qty
  ); // not got success

here see the image i unable to fetch the data

please tell me the method name if can fetch live IEP during the CAS session
