+# Flow 8.4 — List Trading (Dealer Response)
+
+## Overview
+
+Flow 8.4 defines how a **dealer** responds to a client's Request for Quote (RFQ) through Tradeweb (TW) in a List Trading context. The key rule is:
+
+> **The dealer NEVER sends an ExecutionReport (35=8). Only Tradeweb does.**
+
+The dealer's role is limited to:
+- Acknowledging messages (35=AI QuoteStatusReport, 35=BN ExecutionAck)
+- Sending a price quote (35=S)
+
+This document covers the **happy path** (client accepts) and two **alternative flows**:
+- **Flow 8.6 — Trade Ended:** Client cancels before or after receiving the quote
+- **QuoteAck Rejected:** TW rejects the dealer's quote
+
+## Participants
+
+| Abbreviation | Role |
+|---|---|
+| **TW** | Tradeweb — the platform that orchestrates the trade |
+| **Dealer** | Us — responds to RFQs with quotes and acknowledges TW messages |
+| **Client** | The counterparty requesting a quote (we never communicate with them directly) |
+
+## Message Flow

+
+## Step-by-Step Detail
+
+### Step 1 — QuoteRequest (35=R) — TW → Dealer
+
+TW sends an RFQ on behalf of the client. Key fields:
+
+| Tag | Field | Example | Notes |
+|-----|-------|---------|-------|
+| 131 | QuoteReqID | `LST_20260316_BYMA_CORI_NY1567246.1_1` | Always starts with `LST_` for List Trading |
+| 66 | ListID | `NY1567246.1` | Identifies the list/inquiry |
+| 48 | SecurityID | `040114HT0` | Bond identifier |
+| 22 | SecurityIDSource | `1` (CUSIP) | Could also be `4` (ISIN) |
+| 54 | Side | `2` (SELL) | The client's side — if client sells, dealer buys |
+| 38 | OrderQty | `10000` | Quantity requested |
+| 15 | Currency | `USD` | Settlement currency |
+| 64 | SettlDate | `20260317` | Settlement date |
+| 20073 | NegotiationType | `RFQ` | Must be RFQ for this flow |
+
+**Validation:** The dealer must verify `LST_` prefix, non-empty `ListID`, and `NegotiationType=RFQ` before proceeding.
+
+### Step 2 — QuoteStatusReport (35=AI) — Dealer → TW
+
+The dealer acknowledges receipt of the QuoteRequest.
+
+| Tag | Field | Value |
+|-----|-------|-------|
+| 131 | QuoteReqID | Same as received |
+| 117 | QuoteID | Same as QuoteReqID |
+| 297 | QuoteStatus | `0` (ACCEPTED) |
+
+### Step 3 — Quote (35=S) — Dealer → TW
+
+The dealer sends a price quote.
+
+| Tag | Field | Example | Notes |
+|-----|-------|---------|-------|
+| 117 | QuoteID | Same as QuoteReqID | |
+| 131 | QuoteReqID | Same as received | |
+| 132 | BidPx | `99.60000000` | Set when client side is SELL (dealer bids) |
+| 133 | OfferPx | `99.60000000` | Set when client side is BUY (dealer offers) |
+| 44 | Price | `99.60000000` | The quote price |
+| 423 | PriceType | `1` (Percentage) | |
+| 537 | QuoteType | `211` (SEND_QUOTE) | |
+
+### Step 4 — QuoteAck (35=CW) — TW → Dealer
+
+TW confirms the quote was accepted.
+
+| Tag | Field | Value |
+|-----|-------|-------|
+| 1865 | QuoteAckStatus | `1` (ACCEPTED) |
+
+**Note:** If status is not ACCEPTED, the dealer logs the rejection (including the `Text` field) and cleans up the trade from memory. See [QuoteAck Rejected](#quoteack-rejected-quote-not-accepted) below.
+
+### Step 5 — QuoteResponse (35=AJ) — TW → Dealer
+
+The client has decided to trade (Hit/Lift the quote).
+
+| Tag | Field | Value | Notes |
+|-----|-------|-------|-------|
+| 694 | QuoteRespType | `1` (Hit/Lift) | `2` would be Counter — that's flow 8.5, not handled here |
+| 693 | QuoteRespID | `..._TRDREQ` | Always ends with `_TRDREQ` |
+
+### Step 6 — QuoteStatusReport (35=AI) — Dealer → TW
+
+The dealer acknowledges the trade request (TRDREQACK).
+
+| Tag | Field | Value |
+|-----|-------|-------|
+| 131 | QuoteReqID | Same as received |
+| 693 | QuoteRespID | Same as received |
+| 297 | QuoteStatus | `0` (ACCEPTED) |
+
+### Step 7 — ExecutionReport (35=8) `_LISTEND` — TW → Dealer
+
+TW signals that the due-in window for the list has closed.
+
+| Tag | Field | Value | Notes |
+|-----|-------|-------|-------|
+| 17 | ExecID | `..._LISTEND-{timestamp}` | Contains `_LISTEND` |
+| 150 | ExecType | `A` (PendingNew) | |
+| 39 | OrdStatus | `A` (PendingNew) | |
+
+**Dealer action:** Send ExecutionAck only. **Do NOT send an ExecutionReport back.**
+
+### Step 8 — ExecutionAck (35=BN) — Dealer → TW
+
+| Tag | Field | Value |
+|-----|-------|-------|
+| 37 | OrderID | Same as received |
+| 17 | ExecID | Same as received |
+| 1036 | ExecAckStatus | `1` (ACCEPTED) |
+
+### Step 9 — ExecutionReport (35=8) `_TRDEND` — TW → Dealer
+
+TW sends the trade result.
+
+| Tag | Field | Value | Notes |
+|-----|-------|-------|-------|
+| 17 | ExecID | `..._TRDEND-{timestamp}` | Contains `_TRDEND` |
+| 150 | ExecType | `F` (Trade) | The trade was executed |
+| 39 | OrdStatus | `2` (Filled) | |
+| 44 | Price | `99.6` | Final execution price |
+
+**Dealer action:** Send ExecutionAck. Clean up internal trade tracking state.
+
+### Step 10 — ExecutionAck (35=BN) — Dealer → TW
+
+Same format as Step 8.
+
+### Step 11 — ExecutionReport (35=8) `_TRDSUMM` — TW → Dealer
+
+TW sends the full trade summary with additional details (parties, settlement info, trade IDs).
+
+| Tag | Field | Value | Notes |
+|-----|-------|-------|-------|
+| 17 | ExecID | `..._TRDSUMM-{timestamp}` | Contains `_TRDSUMM` |
+| 150 | ExecType | `F` (Trade) | |
+| 39 | OrdStatus | `2` (Filled) | |
+| 453 | NoPartyIDs | Party information | Counterparty details |
+| 526 | SecondaryClOrdID | `TRD_...` | Tradeweb trade reference |
+| 1003 | TradeID | `20260316.BYMA.CORI.230` | Unique trade identifier |
+
+**Dealer action:** Send ExecutionAck. Log the summary for audit/reconciliation.
+
+### Step 12 — ExecutionAck (35=BN) — Dealer → TW
+
+Same format as Step 8.
+
+---
+
+## Alternative Flows
+
+### Flow 8.6 — Trade Ended (Client Cancels)
+
+The client changes their mind and ends the trade. This can happen at any point after the QuoteRequest — even before the dealer's quote arrives. TW informs the dealer via QuoteResponse (35=AJ) messages with `_TRDEND` and `_TRDSUMM` suffixes instead of the ExecutionReport chain.
+
+> **Critical:** The dealer MUST send a QuoteStatusReport (35=AI) ACK for every QuoteResponse. If no ACK is sent, TW will retry the message indefinitely (~every 11 seconds).

+      │                                            │
+```
+
+#### Step 3 — QuoteResponse (35=AJ) `_TRDEND` — TW → Dealer
+
+TW notifies that the client ended the trade.
+
+| Tag | Field | Value | Notes |
+|-----|-------|-------|-------|
+| 693 | QuoteRespID | `..._TRDEND` | Suffix identifies this as trade end |
+| 694 | QuoteRespType | `7` (End Trade) | |
+| 131 | QuoteReqID | Same as original | |
+
+**Dealer action:** Send QuoteStatusReport (35=AI) with `693=QuoteRespID` and `297=0` (ACCEPTED).
+
+#### Step 5 — QuoteAck (35=CW) `REJECTED` — TW → Dealer
+
+If the dealer's Quote (35=S) crossed with the TRDEND, TW rejects it. The QuoteAckStatus will be `2` (REJECTED) with a text like "DPL DLRQUOTE received in an invalid state."
+
+**Dealer action:** Log the rejection and clean up the trade from memory.
+
+#### Step 6 — QuoteResponse (35=AJ) `_TRDSUMM` — TW → Dealer
+
+TW sends the final trade summary confirming the outcome.
+
+| Tag | Field | Value | Notes |
+|-----|-------|-------|-------|
+| 693 | QuoteRespID | `..._TRDSUMM` | Final summary message |
+| 694 | QuoteRespType | `7` (End Trade) | |
+| 22636 | TradeSummary | `Y` | Confirms this is the summary |
+
+**Dealer action:** Send QuoteStatusReport (35=AI) ACK. Clean up the trade from memory. This is the **terminal message** — no more messages will follow for this QuoteReqID.
+
+---
+
+### QuoteAck Rejected (Quote Not Accepted)
+
+If TW rejects the dealer's Quote (35=CW with status != ACCEPTED), the trade is dead from the dealer's perspective.
+
+```
+     TW                                          Dealer
+      │                                            │
+      │  1-3. (same as happy path)                 │
+      │                                            │
+      │  4. QuoteAck (35=CW) [REJECTED]            │
+      │     QuoteAckStatus != 1                    │
+      │ ─────────────────────────────────────────> │
+      │                                            │
+      │     Trade is terminated.                   │
+      │                                            │
+```
+
+**Dealer action:** Log the rejection (including the `Text` field with the reason) and remove the trade from memory. No further action needed — TW may or may not send subsequent messages for this QuoteReqID.
+
+---
+
+## QuoteRespID Suffix Routing in `handleQuoteResponse`
+
+All QuoteResponse (35=AJ) messages are routed by the suffix of the `QuoteRespID` (tag 693):
+
+```
+QuoteRespID ends with "_TRDREQ"   → Trade request (flow 8.4 happy path) — ACK
+QuoteRespID ends with "_TRDEND"   → Trade ended by client (flow 8.6) — ACK
+QuoteRespID ends with "_TRDSUMM"  → Trade summary (flow 8.6 final) — ACK + cleanup
+QuoteRespID ends with "_LISTEND"  → List ended — ACK
+Other suffix                       → Ignored (logged)
+```
+
+## Code Reference
+
+The implementation lives in `src/client/fix/manager.go`:
+
+| Handler | Triggers on | Action |
+|---------|------------|--------|
+| `handleQuoteRequest` | 35=R | Sends 35=AI (ack) + 35=S (quote) |
+| `handleQuoteAck` | 35=CW | If rejected: logs + cleans up trade. If accepted: logs |
+| `handleQuoteResponse` | 35=AJ | Sends 35=AI (ACK). Routes by QuoteRespID suffix. Cleans up on `_TRDSUMM` |
+| `handleExecutionReport` | 35=8 | Sends 35=BN (ack) + routes by ExecID suffix |
+| `sendQuoteStatusReport` | — | Builds 35=AI for QuoteRequest ack |
+| `sendTradeRequestAck` | — | Builds 35=AI for QuoteResponse ack (all suffixes) |
+| `sendExecutionAck` | — | Builds 35=BN for ExecutionReport ack |
+
+### ExecID Routing in `handleExecutionReport`
+
+```
+ExecID contains "_LISTEND"  → Log only, await trade result
+ExecID contains "_TRDEND"   → Log trade end
+ExecID contains "_TRDSUMM"  → Log trade summary + cleanup trade from memory
+ExecType = F (fallback)     → Log generic trade result
+```
+
+The order matters: ExecID suffix checks run before ExecType checks, because `_TRDEND` and `_TRDSUMM` both have `ExecType=F`.
+
+### Trade Cleanup Paths
+
+A trade is removed from memory in any of these scenarios:
+
+| Trigger | Message | Condition |
+|---------|---------|-----------|
+| QuoteAck rejected | 35=CW | `QuoteAckStatus != ACCEPTED` |
+| QuoteResponse summary | 35=AJ | `QuoteRespID` ends with `_TRDSUMM` (flow 8.6) |
+| ExecutionReport summary | 35=8 | `ExecID` contains `_TRDSUMM` (flow 8.4) |
+
+The `loadActiveTrades` recovery function replays today's messages and applies the same cleanup rules to reconstruct accurate state on restart.
