# Trade data and label semantics

## What a row represents

Trade data models a wallet's next observed transaction. Structured split rows include wallet, market, block/log position, transaction side, position before and after the transaction, derived action labels, and market/price features. Model-ready benchmark rows convert this context into text and a structured target.

## Principal source files

- `dataset/Trade/source/trade_price_matched.parquet`: upstream price-matched trade table.
- `dataset/Trade/source/behavior_fixcost.parquet`: 11,531,670 rows with behavior, position, PnL, and K-line features.
- `dataset/Trade/source/market_semantic.parquet`: market semantic metadata.


## Important structured columns

| Group | Columns | Interpretation |
|---|---|---|
| Identity | `wallet`, `market_id`, `outcome` | Wallet and traded outcome. |
| Market text | `event_slug`, `question`, `market_slug` | Semantic context. |
| Ordering | `block`, `log_index`, `tx_hash` | On-chain event location and identifier. |
| Trade | `side`, `amount_int`, `delta_pos` | Observed trade side, amount, and position delta. |
| Action labels | `action_label`, `behavior_label_fine` | Derived behavioral targets. |
| Position | `prev_pos`, `new_pos`, `position_size`, `position_change` | Position state and change. |
| Sequence | `seq_idx_outcome`, `seq_idx_market`, gap and previous-trade fields | Within-wallet behavioral ordering features. |
| Open/close/flip | `is_open_trade`, `is_close_trade`, `flip_*`, `switched_*` | Derived state-transition indicators. |
| Value/PnL | `cost_basis_avg`, `mark_price`, `unrealized_pnl_*` | Position valuation features. |
| K-line | `k0_*` through `k5_*` | Released multi-window market-price features. |

The structured split files additionally include `prior_same_market_trades`.

## Model-ready target

Direct benchmark files contain:

```text
sample_id, task_type, split, wallet, input_text, target, output_format
```

Representative targets request:

```json
{"direction": "increase | decrease | close", "amount_usdc_est": 0.0}
```

Interpretation:

- `increase`: add exposure to the current outcome;
- `decrease`: reduce exposure without the released prompt treating it as a full close;
- `close`: close the position.

The released benchmark uses these derived action and amount labels consistently across its model-ready interfaces.
