AutoPredict

Quick Start — Simple Examples

New to AutoPredict? Start here before reading the full docs.

1. Scan what's trending on Polymarket right now

python3 predict.py --top 10

Shows the 10 most active markets with spreads, depth, and overround signals.

2. Show me the 5 most liquid markets

python3 predict.py --top 5 --verbose

Lists markets sorted by liquidity with full execution details.

3. Browse multi-outcome events for structural mispricing

python3 predict.py --events --top 10

Checks whether event probabilities sum to more or less than 100%.

4. What does the order book look like for a specific market?

python3 predict.py --fair 0.55 <condition_id>

Replace <condition_id> with the Polymarket ID. Provide your own fair probability estimate and AutoPredict evaluates the trade.

Run python3 predict.py --help for all flags. No credentials required for live reads.

---

AutoPredict is an execution framework for prediction-market trading. It is not a forecasting model.

• You provide fair_prob.
• The repo evaluates execution quality: side, order type, size, spread, depth, slippage, and risk.
• Live market reads require internet but no credentials.
• Real trading is scaffolded, not production-ready.

This skill was audited against the upstream repository layout and command surface, not just the README.

What Is Real vs Scaffold

Reliable entry points

• python3 predict.py scans live Polymarket markets.
• python3 predict.py --events inspects multi-outcome event overround / underround.
• python3 predict.py --fair 0.60 <condition_id> evaluates one market using your explicit probability.
• python3 -m autopredict.cli backtest --dataset ... runs an offline backtest.
• python3 -m autopredict.cli score-latest prints the most recent saved metrics JSON.

Partially implemented or scaffold-only

• python3 -m autopredict.cli learn analyze only works if you already have JSONL trade logs. Plain CLI backtests do not create those logs.
• python3 -m autopredict.cli learn tune and learn improve are placeholders that point to a nonexistent scripts/learn_and_improve.py.
• python3 -m autopredict.cli trade-live is intentionally disabled by config.
• scripts/run_paper.py and scripts/run_live.py are deployment scaffolds. run_live.py uses a MockVenueAdapter, so it is not a real exchange adapter.

Repo Map

• predict.py: live Polymarket scanner and one-off evaluation path.
• autopredict/cli.py: packaged CLI used for backtest, score-latest, and learning commands.
• run_experiment.py: simple offline backtest harness used by autopredict.cli backtest.
• strategy_configs/*.json: strategy knobs for offline experiments.
• autopredict/_defaults/datasets/sample_markets.json: bundled sample dataset. Use this when you need a known-good backtest input.
• autopredict/learning/tuner.py: reusable grid-search API. Better than the stub CLI.
• scripts/run_paper.py, scripts/run_live.py: paper/live monitoring templates.

Decision Tree

1. Choose the workflow

If the user wants to:

• Find liquid live markets or structural event mispricing: use predict.py via scripts/scan_markets.sh.
• Evaluate one market with a known fair probability: use predict.py --fair ....
• Compare strategy configs or produce reproducible metrics: use python3 -m autopredict.cli backtest --dataset ... via scripts/run_backtest.sh.
• Sweep parameters safely: use scripts/tune_params.sh. Do not use python3 -m autopredict.cli learn tune.
• Inspect trade logs: use python3 -m autopredict.cli learn analyze --log-dir ... only if JSONL logs already exist.
• Discuss paper/live deployment scaffolds: read docs/DEPLOYMENT.md, configs/*.yaml, and the Python runners before claiming the repo can trade live.

2. Choose the command surface

• Use predict.py for live reads and one-off agent evaluation.
• Use python3 -m autopredict.cli ... for reproducible offline backtests.
• Avoid python3 -m autopredict.backtest.cli ...; that submodule has brittle import behavior in the current repo state.

3. Choose the data source

• For a quick smoke test: use autopredict/_defaults/datasets/sample_markets.json.
• For real research: require a user-supplied dataset of historical snapshots.
• If the user has no dataset and wants strategy performance claims, stop and say the repo cannot produce a valid backtest without one.

Setup

Preferred helper:

bash skills/autopredict/scripts/setup.sh --dir /tmp/autopredict

Manual setup:

git clone https://github.com/howdymary/autopredict.git /tmp/autopredict
cd /tmp/autopredict
python3 -m pip install -e .
python3 predict.py --help
python3 -m autopredict.cli --help

After setup, keep work inside the cloned repo when invoking upstream commands.

Opinionated Workflows

Workflow A: Fast live market triage

Use this when the user wants ideas, not a PnL claim.

cd /tmp/autopredict
python3 predict.py --top 10 --verbose
python3 predict.py --events --top 10

Interpretation:

• Prefer markets with tight spreads and visible depth.
• Treat event underround as a structural clue, not automatic free money.
• Only move to trade evaluation once you can justify a fair_prob.

Workflow B: Evaluate a single conviction

Use this when the user already has a thesis on one market.

cd /tmp/autopredict
python3 predict.py --fair 0.60 <condition_id>

Important caveat:

• predict.py --fair constructs AutoPredictAgent(AgentConfig()) directly.
• That means it uses default agent parameters, not strategy_configs/baseline.json or your edited JSON config.
• Use it as a default-policy sanity check, not as proof that a tuned config behaves the same way.

Workflow C: Backtest a strategy config

Use this when the user wants reproducible metrics or config comparisons.

cd /tmp/autopredict
python3 -m autopredict.cli backtest \
  --config strategy_configs/baseline.json \
  --dataset autopredict/_defaults/datasets/sample_markets.json

python3 -m autopredict.cli score-latest

Opinionated rule:

• Always pass --dataset.
• The repo default config.json sets "default_dataset": null.
• Running python3 -m autopredict.cli backtest with no dataset currently throws a TypeError.

Workflow D: Tune parameters

Use the bundled helper instead of the stub CLI:

bash skills/autopredict/scripts/tune_params.sh \
  --dir /tmp/autopredict \
  --dataset autopredict/_defaults/datasets/sample_markets.json \
  --param min_edge 0.03,0.05,0.08 \
  --param aggressive_edge 0.10,0.12,0.15

Opinionated tuning rules:

• Start with 1-2 parameters, not 6.
• Prefer sharpe or total_pnl only after sample size is reasonable.
• Reject “best” configs with too few trades.
• Save every run; do not trust memory or terminal output.

Workflow E: Review learning / deployment scaffolds

Use this when the user asks about self-improvement, paper trading, or live trading.

• autopredict.learning.tuner.GridSearchTuner is real and reusable.
• python3 -m autopredict.cli learn tune is just a message, not a tuning engine.
• scripts/run_paper.py is a monitoring loop template; it does not fetch real markets or execute the full agent logic.
• scripts/run_live.py requires confirmation and safety flags, but still uses MockVenueAdapter, so it cannot trade a real venue out of the box.

Strategy Knobs That Matter

Main JSON parameters in strategy_configs/*.json:

• min_edge: minimum edge before any trade is considered.
• aggressive_edge: threshold for using market orders more aggressively.
• max_risk_fraction: position sizing as fraction of bankroll.
• max_position_notional: hard dollar cap per order.
• min_book_liquidity: minimum visible depth required.
• max_spread_pct: spread filter.
• max_depth_fraction: cap as fraction of visible depth.
• split_threshold_fraction: start slicing when order is too large relative to depth.

Opinionated tuning guidance:

• Lower min_edge only if trade count is too low.
• Raise aggressive_edge if slippage is the dominant problem.
• Lower max_depth_fraction before touching risk caps when market impact is the problem.
• Do not loosen spread and liquidity filters at the same time; you will not know which one caused the regression.

Failure Modes and Edge Cases

Backtest failures

• TypeError before the backtest starts: almost always because no --dataset was passed and default_dataset is null.
• No metrics.json found under state directory: score-latest was run before a successful backtest.
• Malformed JSON errors: invalid strategy config or dataset schema.

Learning workflow failures

• learn analyze reports no logs: expected unless you created JSONL logs with TradeLogger or a scaffold that writes them.
• learn tune / learn improve prints advice only: expected. Those subcommands are placeholders.
• Docs mention scripts/learn_and_improve.py: that script does not exist in the audited upstream repo.

Live / paper trading confusion

• Paper trading is not the same as live market scanning: run_paper.py is a loop scaffold, not an end-to-end paper execution engine over Polymarket.
• Live trading docs sound complete, but adapter is mock: run_live.py cannot place real venue orders without extra implementation.
• trade-live CLI is disabled: config.json defaults live_trading_enabled to false.

Command-path gotchas

• Do not use python3 -m autopredict.backtest.cli in this repo state unless you are ready to debug import-path issues.
• Do not assume root docs and packaged CLI are fully synchronized. The package path under autopredict/ is the safer source of truth.
• Do not claim config changes affect predict.py --fair unless you verified the code path. It currently ignores strategy_configs/*.json.

Helper Scripts Bundled With This Skill

• scripts/setup.sh: clone, install, verify, and smoke-test the repo.
• scripts/scan_markets.sh: wrapper around predict.py for live scan / --events / --fair paths.
• scripts/run_backtest.sh: safe backtest wrapper that always provides a dataset or fails with a useful error.
• scripts/tune_params.sh: grid-search wrapper that bypasses the upstream stub tuning CLI.

Recommended Agent Behavior

When using this skill:

• Lead with the limitation that AutoPredict optimizes execution, not prediction.
• Ask where fair_prob comes from before discussing edges as if they were alpha.
• Require a dataset for any serious backtest claim.
• Separate “works in the repo” from “documented in the repo”.
• Treat paper/live trading as architecture review unless the user is explicitly asking to extend the scaffold.

Autoresearch Pairing

Use this skill with autoresearch when the user wants disciplined tuning.

Recommended setup:

1. Define the target metric, usually sharpe, total_pnl, or avg_slippage_bps.
2. Use scripts/run_backtest.sh or scripts/tune_params.sh as the experiment workload.
3. Keep one hypothesis per run.
4. Store configs and metrics under a dated output directory.

Good autoresearch prompt framing:

• “Optimize aggressive_edge and max_depth_fraction for lower slippage without collapsing trade count.”
• “Improve Sharpe on this dataset while keeping max drawdown below 35%.”

Bad framing:

• “Make it profitable” with no dataset.
• “Tune everything” with no metric priority.
