feat: copy-trading replay & comparison system#1
Merged
Conversation
Adds SizingStrategy, Target, TradeComparison, Comparison, ReplayResult dataclasses and TargetNotFoundError, UsernameResolutionError, ReplayError error classes to support the copytrack feature.
Adds copytrack_targets and copytrack_replays tables to SCHEMA_SQL. Updates reset() to drop copytrack tables first (FK order) before re-creating the full schema.
Creates pm_trader/data_api.py with PolymarketDataClient and get_activity() method that fetches a single page of user activity from the Polymarket Data API, with optional time range and sort parameters.
…aClient Adds auto-paginating get_all_trades() for complete trade history retrieval, get_positions() for current user positions, and get_profile() for public profile lookup via the Gamma API.
Adds resolve_username() that scrapes the Polymarket profile page to extract a wallet address from the Next.js __NEXT_DATA__ payload, with in-memory caching to avoid duplicate requests.
Implements Task 7: creates pm_trader/copytrack.py with compute_replay_amount() supporting equal, proportional, and fixed sizing modes, with tests.
Implements Task 8: adds compute_original_stats() to copytrack.py, computing buy/sell counts, total invested/returned, PnL, and win rate from raw Polymarket Data API trade records.
Implements Task 9: adds replay() to copytrack.py that replays a target user's trades directly into the paper trader DB at original prices, handles buy/sell sizing modes, skips on insufficient balance or missing position, and produces a full ReplayResult with per-trade and aggregate comparisons.
Add copytrack command group with add (by @username or 0x address), list (all tracked targets), and remove subcommands. Includes 5 tests.
Add trades command to fetch user trade history from Data API, and replay command to replay a target's trades through the paper trader with comparison stats. Includes 2 new tests.
Add compare subcommand to view the latest replay comparison for a tracked target, including original vs replay stats and per-trade breakdown. Includes 1 new test.
Add /api/copytrack/targets endpoints (GET, POST, DELETE) for managing copy-trade targets via the web API. Register copytrack router in app.py.
Add POST /api/copytrack/replay to trigger copy-trade replays,
GET /api/copytrack/replay/{id} to fetch results, and
GET /api/copytrack/chart/{id} for P&L curve data.
Replace deprecated /closed-positions API with /activity endpoint (TRADE + REDEEM). Replay engine now processes BUY, SELL, and REDEEM activities chronologically. REDEEM win/loss determined by API usdcSize (>0 = won, 0 = lost). - Add REDEEM handling: winning positions get cash back, losing positions zeroed out - Add `type` column to copytrack_raw_trades for TRADE/REDEEM deduplication - Update limit parameter to count by market (conditionId), not individual activities - Add Copytrack frontend page with per-trade comparisons and charts - Add open market indicators (yellow bg + ⏳) for unredeemed positions - Add replay history pagination (show 5 by default) - Add live E2E test verifying limit=1 aligns with latest real activity - 818 tests pass, 100% coverage
