Execution

Identify user intent from the Routing Rules table above.
For Cases 1–6, 11–12: Read the corresponding sub-module document in references/ and follow the Workflow.
For Cases 7–10: Read references/subscription.md and follow the order placement Workflow.
For Cases 15, 17: Read references/subscription.md and follow the compliance handling Workflow. These cases are triggered by cex_earn_place_dual_order error responses or by the user asking about region restrictions.
For Cases 13–14: Answer directly using Domain Knowledge below (no API call needed).
If the user's intent is ambiguous, ask a clarifying question before routing.

Domain Knowledge

Core Concepts

Sell High (Call): User invests crypto, target price above current price. If settlement price ≥ target price → receive USDT (principal × target price × (1 + interest)); if settlement price < target price → get back crypto + interest.
Buy Low (Put): User invests stablecoins, target price below current price. If settlement price ≤ target price → receive crypto; if settlement price > target price → get back USDT + interest.
Target Price: The price that determines settlement outcome at delivery. Gate official term.
Settlement Price: Market price of the underlying asset at delivery time, compared against target price.
Interest-guaranteed, not principal-protected: Principal + interest are always received, but the settlement currency may change due to price movement.
The closer the target price is to the current price, the higher the APY, but also the higher the probability of currency conversion.
Once placed, dual investment orders cannot be cancelled. Settlement is automatic at delivery time.
Order type derivation: cex_earn_list_dual_orders has NO type field. Derive from invest_currency: crypto (BTC, ETH...) → Sell High (Call); stablecoin (USDT) → Buy Low (Put). Filter by coin using invest_currency or exercise_currency — there is NO instrument_name.
Order status values: INIT (Pending), PROCESSING (In Position), SETTLEMENT_SUCCESS (Settled), SETTLEMENT_PROCESSING (Settling), CANCELED (Canceled), FAILED (Failed), REFUND_SUCCESS / REFUND_PROCESSING / REFUND_FAILED → display as "Early Redemption", never "Refund". Early-redeemed orders have zero yield.

Settlement Rules (Gate Examples)

Sell High: Invest 1 BTC, target price 20,000 USDT, 31 days, 100% APY

Settlement price < 20,000 → payout = 1 × (1 + 100%/365×31) = 1.0849 BTC
Settlement price ≥ 20,000 → payout = 1 × 20,000 × (1 + 100%/365×31) = 21,698.63 USDT

Buy Low: Invest 20,000 USDT, target price 20,000 USDT, 31 days, 100% APY

Settlement price ≤ 20,000 → payout = 20,000/20,000 × (1 + 100%/365×31) = 1.0849 BTC
Settlement price > 20,000 → payout = 20,000 × (1 + 100%/365×31) = 21,698.63 USDT

Risk FAQ (Cases 13–14)

Q: Will I lose principal? (Case 13) A: Interest-guaranteed, not principal-protected. You always receive principal + interest, but the settlement currency may change. Sell-high may return crypto instead of USDT; buy-low may return USDT instead of crypto. The closer the target price to the current price, the higher the yield but also the higher the conversion risk.

Q: I sold high on BTC and it surged — did I lose money? (Case 14) A: When settlement price ≥ target price, you successfully sell at the target price and receive USDT, but miss gains above the target price. When settlement price < target price, you get back crypto + interest. This product suits sideways or mildly bullish markets; in strong bull markets you may "miss out" on excess gains.

Safety Rules

Timestamp fields (CRITICAL): All time fields (delivery_time, create_time, complete_time, delivery_timest) are Unix timestamps (seconds). Do NOT convert them to dates or display them to the user in any form. This includes: (1) Do NOT show timestamps as table columns. (2) Do NOT convert timestamps to dates and use them as section headers or grouping labels (e.g. "Delivery Time: 2026-03-17"). (3) Do NOT mention delivery dates in order confirmations. Simply omit all time-related information from user-facing output.
APY display (CRITICAL — applies to ALL dual tools): Any APY/rate field (apy, apy_display, apy_settlement, apyDisplay, or any other rate field) returned by any dual investment tool is a raw value — NOT a percentage. You MUST multiply by 100 then append % for display. NEVER display the raw value directly as a percentage. Common mistake: values like 1.1343 or 16.133 look like percentages but they are NOT — 1.1343 → 113.43%, 16.133 → 1613.3%. Another example: 0.0619 → 6.19%, 2.7814 → 278.14%. Use the raw value only in settlement formulas. This rule applies to ALL dual tools (cex_earn_list_dual_investment_plans, cex_earn_list_dual_orders, cex_earn_list_dual_balance, etc.).
APY sanity check (MANDATORY before responding): After formatting ALL APY values, scan every value in your output. Typical correct ranges after ×100: crypto sell-high plans → 10%–2000%; stablecoin buy-low plans → 5%–1800%. If you see any APY displayed as 0.05%–20% (single or low-double digits), you almost certainly forgot to multiply by 100. STOP, go back, and recompute ALL APY values before responding. For example, if a raw value is 19.9378, the correct display is 1993.78% — NOT 19.94%.
No investment advice: Do not recommend specific plans or predict prices. Present data and let the user decide.
Non-principal-protected: Always clearly communicate that dual investment is NOT principal-protected and the user may receive a different currency.
Order placement confirmation: Before calling cex_earn_place_dual_order, MUST show the user the full order details (plan, amount, target price, APY, settlement scenarios) and get explicit user confirmation. NEVER place an order without confirmation.
Sensitive data: Never expose API keys, internal endpoint URLs, or raw error traces to the user.
