See the stock and crypto steps in the connection guide above. Issue an API key with your brokerage or exchange and register it in Quantus.

Only accounts in your name can be registered. Accounts belonging to another person, including family members, cannot be registered.

Your assets remain in your own account. Quantus only sends orders to the connected account and operates the following security measures.

Encrypted storage: Sensitive information such as API keys and personal data is protected with AES-256 and other industry-leading methods.

Trading-only permissions: Live-trading API keys use only Read / Trade permissions; withdrawal permissions are never requested.

Infrastructure: The Azure-based environment has global security certifications and blocks external threats with firewalls and intrusion detection systems (IDS/IPS).

Operating times depend on the strategy market. All times use Korea Standard Time.

Korean strategies: Portfolio extraction at 22:00 the day before rebalance → trading preparation at 07:00 (cannot cancel) → pre-market orders 08:20–08:30 → regular session 09:00–15:20 → after-hours orders 15:30–15:40 → portfolio updates from 16:00. Complete the next-day rebalance reservation before 21:00.

US strategies: Portfolio extraction at 20:00 → trading preparation at 22:00 (cannot cancel) → regular session 23:30–06:00 the next day → portfolio updates from 10:00 the next day. Complete the same-day rebalance reservation before 19:00.

Global strategies: Portfolio extraction begins at 21:00; after extraction completes, strategy changes and cancellation are available until 22:00. Complete the same-day rebalance reservation before 20:00.

There can be several reasons for an unfilled order.

Common reasons: insufficient cash, slippage beyond the allowed range, insufficient liquidity, overseas trading or overseas ETP trading not enabled, integrated-margin service not enabled (global strategies).

Solution: Apply for overseas trading and integrated margin at your brokerage. For cash, slippage or liquidity issues, increase the TWAP window and try splitting the trade across several days.

If many positions remain unfilled for two to three business days after trying these steps, contact customer support.

For stocks, all additional deposits are automatically reflected at the next allocation adjustment. For crypto, press the increase button to apply the increase; the added amount is then reflected automatically.

Live investing and backtests cannot deliver exactly the same returns because of the following differences.

Backtest: Monthly-start rebalance (monthly basis), assumed closing-price fills (zero slippage), all filled within one business day

Live investing: Monthly-start rebalance or first entry on a selected date, trades only within the allowed slippage range, and may not fill everything within one business day

These differences mean live investing cannot guarantee the same result as a backtest. Past performance does not guarantee future results.

Results can differ for several reasons.

Data differences: Data vendor, rebalance date and aggregation unit (Quantus aggregates statistics using daily data)

Logic differences: Backtest logic, indicator definitions and factor calculation logic

Example · PER: Market-cap definition (whether listed shares are considered, etc.) and net-income definition (controlling interest / total, quarterly / annual, TTM / closest filing)

It is used for validation, portfolio extraction and decile tests. It is separate from Q credits and is no longer available for new purchase.

Fixed-term: If you have not used the service at all, you may withdraw within seven days of payment. Even within that period, withdrawal is limited under Article 17(2)(5) of the E-Commerce Act if you have used the service. If a refund is due, it will be returned to the payment method within three business days of receiving your request.

Subscription: Apply directly under the refund policy and process of the platform where the payment was made (Google Play Store, Apple App Store, etc.). After cancelling, you can use the service until the next scheduled payment date; no separate refund is issued for the remaining period.

All passes are fixed-term, one-time purchases and do not renew automatically when the term ends.
