KOSPI/KOSDAQ Market Data and Broker Checklist for Korean Technical Traders
A provider-neutral checklist for confirming KOSPI and KOSDAQ market-data access, entitlements, and broker API readiness before building a chart workflow.
Before building a KOSPI or KOSDAQ chart-review workflow, a trader needs to confirm what their own account, broker, and provider setup actually allows. This checklist is provider-neutral — it does not recommend a specific data feed or broker.
Quick Answer
Confirm four things before building a KOSPI/KOSDAQ chart workflow: market-data entitlement status, real-time versus delayed feed behavior, symbol and historical-depth coverage, and whether the broker or provider exposes an API a desktop tool can actually use.

Why This Isn't a One-Time Check
KOSPI and KOSDAQ market-data access depends on account-level entitlements that can differ by broker, residency, account type, and exchange agreement — not just by which platform a trader opens an account with.
A trader who confirmed access once, then changed brokers, account tier, or provider, should re-confirm rather than assume the same entitlements carried over.
The Checklist
Work through these items before assuming a KOSPI/KOSDAQ chart workflow is ready to build on.
| Check | Question to Answer | Why It Matters |
|---|---|---|
| Entitlement status | Does the account have live KOSPI/KOSDAQ market-data entitlements, or only delayed data? | Delayed data changes what a chart review workflow can support |
| Symbol coverage | Are the specific KOSPI/KOSDAQ symbols needed actually available through the provider? | Coverage gaps are common outside large-cap names |
| Historical depth | How far back does historical data go for the symbols in question? | Backtesting and pattern review need sufficient depth |
| API access | Does the broker or provider expose an API a desktop chart tool can connect to? | Some Korean brokers are execution-focused with limited third-party API access |
| Account tier | Does the current account tier include the data package needed, or is an upgrade required? | Entitlements are often tier-gated, not universal |
Where MyLinedChart Fits
MyLinedChart does not provide KOSPI or KOSDAQ market data itself. It connects to a trader's own IBKR session through a local Connector and gives chart work a structured review and export layer once the underlying data access is in place.

Limits and Claims to Keep Clear
This checklist is educational. It is not investment, trading, tax, legal, or financial advice, and it does not recommend a KOSPI/KOSDAQ broker, data vendor, or account tier.
MyLinedChart is global software from Little Bird Trading LLC. It does not guarantee KOSPI, KOSDAQ, or US market data, exchange entitlements, or broker API access.
FAQ
Does MyLinedChart provide KOSPI or KOSDAQ market data?
No. Market data depends on the trader's own broker, provider, account, and exchange entitlements. MyLinedChart's own connectivity is IBKR-based only, through the local Connector.
Does this checklist recommend a Korean data provider or broker?
No. It is a provider-neutral checklist for evaluating the trader's own account setup.
Is real-time KOSPI/KOSDAQ data guaranteed once a broker account is open?
No. Real-time versus delayed data, symbol coverage, and historical depth depend on account-level entitlements that can vary even within the same broker.
