Properties

effectiveUnderlying → SymbolInfo

Available on MarketDataInterface, provided by the MKTDataX extension

The underlying SymbolInfo. Falls back to parseSymInfo when underlyingSymbolInfo is null (i.e. the charted symbol is itself the underlying).
no setter
isEffectiveUnderlyingIndex → bool

Available on MarketDataInterface, provided by the MKTDataX extension

Whether effectiveUnderlying is a spot index (e.g. NIFTY, BANKNIFTY) — as opposed to symbolIsIndex, which asks about the currently charted symbol itself.
no setter
parseFutureSymbols → List<SymbolInfo>

Available on MarketDataInterface, provided by the MKTDataX extension

futureSymbols decoded into SymbolInfos, sorted by expiry. Empty when futureSymbols is null or empty.
no setter
parseIndexSymbols → List<SymbolInfo>

Available on MarketDataInterface, provided by the MKTDataX extension

indexSymbols decoded into SymbolInfos. Empty when indexSymbols is null or empty.
no setter
parseMarketTiming → MarketTiming

Available on MarketDataInterface, provided by the MKTDataX extension

marketTiming decoded into a MarketTiming.
no setter
parseSymInfo → SymbolInfo

Available on MarketDataInterface, provided by the MKTDataX extension

symbolInfo decoded into a SymbolInfo.
no setter
symbolIsIndex → bool

Available on MarketDataInterface, provided by the MKTDataX extension

Whether the currently-charted symbol ITSELF is a spot index (e.g. NIFTY, BANKNIFTY) — as opposed to isEffectiveUnderlyingIndex, which asks about the underlying. Indices have no traded volume, so indicators that read it (e.g. Volume) should be unavailable rather than showing a flat zero; an option/future ON an index still has real volume and must stay unaffected.
no setter

Methods

parseOI({required String underlyingSymbolId, required List<String> expiries}) → Future<OIStrikeValues>

Available on MarketDataInterface, provided by the MKTDataX extension

Convenience wrapper over MarketDataInterface.fetchOI that handles the JSON decode -- see that method's doc for the underlying contract.
parseOIAnalysis({required String underlyingSymbolId, required String expiry, required int timeFrom, required int timeTo, required double atm, int eachSide = 5}) → Future<OIAnalysisSnapshot>

Available on MarketDataInterface, provided by the MKTDataX extension

Convenience wrapper over MarketDataInterface.fetchOIAnalysis that handles the JSON decode and trims the result to the ATM +/- eachSide window (by strike count, not price distance) using atm -- see that method's doc for the underlying contract.
parseOIChange({required String underlyingSymbolId, required List<String> expiries, required int timeFrom, required int timeTo}) → Future<OIStrikeValues>

Available on MarketDataInterface, provided by the MKTDataX extension

Convenience wrapper over MarketDataInterface.fetchOIChange that handles the JSON decode -- see that method's doc for the underlying contract.
