Formula reference
Functions: sma(x,n), ema(x,n), wma(x,n), rsi(x,n), stdev(x,n), highest(x,n), lowest(x,n), sum(x,n), ref(x,n), abs(x), min(a,b,...), max(a,b,...)
Comparisons: > < >= <= only. A formula holds exactly ONE comparison, e.g.
close > sma(close, 50) — there is no and/or. This box is just ONE more condition, ANDed with the ones above — add extra criteria with the condition builder, not by chaining them in here.Examples:
close > sma(close, 50), rsi(close, 14) < 30

Data Providers
Demo — sample data (no broker)
You're viewing a seeded, offline sample SPY chart with example trades. No IBKR connection is required. Connect your own IBKR account any time to switch to live data.
Connected
Market data is fetched locally through your MyLinedChart Connector using your own provider key. Your key stays on this machine — it is never sent to MyLinedChart servers.
Checking IBKR Connector...
Checking local connector status.
Advanced diagnostics
Collecting diagnostics.
--
Use the local IBKR Client Portal Gateway URL (default: https://127.0.0.1:5000/v1/api). Authenticate directly with IBKR. MyLinedChart does not store your IBKR username/password.
Socket Gateway mode requires local MyLinedChart Bridge. If browser blocks HTTP localhost bridge from the hosted app, run the bridge in HTTPS mode and trust the local certificate.
Connector download: /resources/downloads#connector-install
IBKR is local runtime only: no cloud sync and no server-side localhost proxy. Market data availability depends on IBKR permissions/subscriptions.
Client ID must be unique per active API connection.
Choose from detected accounts. Use Auto-select to let connector choose.
