XLNative for Excel on Mac
XLNative streams Interactive Brokers quotes, options IV/Greeks, account values, positions, P&L, and cost basis from your local TWS or IB Gateway session directly into Excel for Mac.
Public beta available now. Free during beta. Current beta build expires August 15, 2026.
Runs locally on your Mac. No Windows, no VBA, no COM. Market, account, position, P&L, and cost-basis data come from your local TWS / IB Gateway session.
More than quotes
XLNative is not just a market-price feed. It brings account summary values, current positions, cost basis, and session P&L into Excel alongside live quotes, so your workbook can track the account and the market from the same local IBKR session.
XN.ACCOUNTS(). XN.ACCOUNT. XN.POSITION, XN.COSTBASIS, and XN.POSITIONS for holdings-level workbook views. XN.PNL. Excel formulas
XLNative formulas update as data arrives from your local TWS or IB Gateway session. Each function is designed for a specific workbook job: market data, account discovery, account values, P&L, positions, cost basis, or a live positions table.
XN.MARKET
Streams live quotes, sizes, option IV, Greeks, and model fields for supported IBKR instruments. If field is omitted, XLNative returns last.
=XN.MARKET("AAPL")=XN.MARKET("SPX:index","last")=XN.MARKET("ES:future:20260813","bid")=XN.MARKET("AAPL:call:105:20260815","askiv")XN.ACCOUNTS
Returns the IBKR account IDs visible from the active local TWS or IB Gateway session. Use details for account metadata when IBKR provides it.
=XN.ACCOUNTS()=XN.ACCOUNTS("details")XN.ACCOUNT
Streams IBKR account-summary values such as NetLiquidation, BuyingPower, ExcessLiquidity, AvailableFunds, and GrossPositionValue.
=XN.ACCOUNT("U12345","NetLiquidation")=XN.ACCOUNT(A2,"BuyingPower")=XN.ACCOUNT("ALL","NetLiquidation")XN.PNL
Streams session P&L from IBKR's P&L subscription. Use unrealized, realized, or daily.
=XN.PNL("U12345","unrealized")=XN.PNL("U12345","realized")=XN.PNL("ALL","daily")XN.POSITION
Streams the current position size for one account and symbol. Flat positions return 0.
=XN.POSITION("U12345","AAPL")=XN.POSITION("U12345","ES:future:20260813")=XN.POSITION("U12345","BTC:crypto")XN.COSTBASIS
Streams average cost basis for the same account and symbol format used by position lookups.
=XN.COSTBASIS("U12345","AAPL")=XN.COSTBASIS("U12345","IBM")XN.POSITIONS
Spills a live table of nonzero positions for a specific account, including Symbol, Position, and CostBasis columns.
=XN.POSITIONS("U12345")=XN.POSITIONS(A2)Market data access
XLNative connects Excel to the live data already available through your local Interactive Brokers (IBKR) TWS or IB Gateway session. If you already subscribe to market data through Interactive Brokers, XLNative can stream that data into Excel without requiring a separate real-time market-data vendor subscription.
XLNative uses the IBKR data available to your TWS / IB Gateway session. No separate real-time data subscription from XLNative is required.
XLNative uses your existing Interactive Brokers real-time market-data allowance. Market-data lines are shared across TWS watchlists and API-connected applications, including XLNative.
In XLNative, each subscribed symbol uses one market-data line, whether it is a stock, option, future, FX pair, crypto contract, index, or CFD. Reusing the same symbol in multiple formulas, or requesting multiple fields for that symbol, does not use additional market-data lines.
After your first month of trading, IBKR provides the largest of:
An account with $2.0 million in USD equity and $400 in monthly commissions receives 200 lines:
An account with $1.0 million in USD equity and $2,400 in monthly commissions receives 300 lines:
IBKR rounds calculated allowances down to a whole number. The 100-line minimum always applies, and TWS watchlists and API requests draw from the same shared allowance.

FAQ
Yes. The current beta is built for M-series Macs running the Microsoft Excel for Mac desktop app, version 16.4 or later. It connects to TWS or IB Gateway running locally.
No. You sign in directly to TWS or IB Gateway as usual. XLNative automatically connects to that local API session on your Mac; Trelliq Labs does not receive your IBKR username or password. XLNative works with read-only API access, and read-only access is recommended.
XLNative does not sell market data. It streams the data available through your local TWS or IB Gateway session. If your IBKR account has the required market-data permissions, XLNative can make that data available in Excel without requiring a separate real-time data subscription from XLNative.
Not at this time, but stay tuned.
Yes. XLNative reads data from your local TWS or IB Gateway session.
You can install and open XLNative, but live Excel formulas need API access enabled in your local TWS or IB Gateway session. Without that local API connection, XLNative cannot stream IBKR data into Excel.
No. The current beta is for M-series Macs and the Excel for Mac desktop app only.
