IOL InvertirOnline data API

InvertirOnline Sociedad de Bolsa S.A.U. · Banking

IOL: Dólar, acciones, ¡y más! is the Android brokerage app from InvertirOnline Sociedad de Bolsa S.A.U., the IOL Inversiones brand within Grupo Supervielle. Argentine retail investors use it to trade BYMA stocks, CEDEARs, bonds and ETFs, buy and sell dólar MEP and CCL, and subscribe to or redeem FCI 24/7 funds such as IOL Dólar Ahorro Plus. It also brings together peso and dollar cauciones, IOL Cripto, and a linked Banco Supervielle account for deposits, withdrawals and plazo fijo. A USA investment wallet can be funded through CCL, while the Inicio, Operar, Mis Inversiones and Mi dinero sections organize trading, holdings and cash. The app serves Argentina's retail investment market alongside other local brokerage platforms such as Balanz and Portfolio Personal Inversiones.

BYMA price snapshots pair ultimoPrecio and variacionPorcentual with session ranges, traded volume and bid/ask puntas for symbols such as GGAL and YPFD. Currency records add dolarMEP, ccl and spread, while peso and dollar cash records distinguish saldo from availableToOperate. FCI records connect fciSymbol and fciYtd to cantidadDeCuotapartes and subscription amounts. Plazo fijo positions carry tna, tea, plazoDias and fechaVencimiento; crypto balances add asset network and wallet totalValuation.

Portfolio tools can value holdings against BYMA prices and available cash, treasury monitors can compare MEP and CCL spreads, and fund operations teams can reconcile subscription orders against the FCI catalog. Wealth dashboards can combine crypto valuation with term-deposit positions and bank-funding details such as cbu, cvu and alias. openData Studio turns these records into callable open data for those integrations.

Where teams use this data

Mark Argentine holdings to BYMA last
A portfolio bot pulls ultimoPrecio, variacionPorcentual and volumenOperado for GGAL, YPFD and CEDEARs, then values tenencia against availableToOperate cash so an advisor dashboard stays in line with the ALYC book.
Watch MEP versus CCL spreads
A treasury feed reads exchangeRate, dolarMEP, ccl, compra, venta and spread from the ARS exchange-rate and buy-sell endpoints to time peso/dollar conversions against the app's dólar MEP and CCL cards.
Reconcile FCI 24/7 subscriptions
A fund ops job matches FCI subscription tickets (fciSymbol, cantidadDeCuotapartes, amount) to the fund reference catalog (fciName, fciYtd) for IOLCUSD and IOLDOLD so custody and the IOL 24/7 clock stay in sync.
Net crypto wallet and plazo fijo cash
A wealth aggregator sums crypto totalValuation with Supervielle plazo fijo positions (tna, tea, plazoDias, fechaVencimiento) and CBU/CVU deposit accounts to show one ARS+USD+crypto sleeve.

Frequently asked questions

Which BYMA quote and dólar MEP/CCL fields are represented?

Quote records include ultimoPrecio, variacionPorcentual, apertura, maximo, minimo, volumenOperado, volumenNominal, cantidadOperaciones and bid/ask puntas with compra and venta. Records identify the symbol, market and settlement term. Currency reference and buy/sell records include exchangeRate, dolarMEP, ccl, compra, venta and spread for comparing peso/dollar pricing.

Which FCI, crypto and plazo fijo fields are included?

Fund records include fciSymbol, fciName, fciYtd and cuotapartesDisponibles, while subscriptions carry amount and cantidadDeCuotapartes. Crypto records distinguish availableToOperate by asset and network from totalValuation. Plazo fijo positions add tna, tea, plazoDias and fechaVencimiento.

What authentication pattern do the examples show?

The token request submits grant_type, username, password and client_id without a prior Bearer token and receives access_token and refresh_token. Later requests use Authorization: Bearer and client metadata headers. Client-specific performance data also requires eligible account access.

Are the example paths and values live brokerage instructions?

No. The paths and sample values are illustrative integration examples rather than a live brokerage contract. They show the roles of quote, balance, fund, crypto and account-performance fields without publishing operational service addresses.
