## Scope and limitations

These are machine-extracted research records, not verified trading systems. Catalog rank measures specification detail and claimed evidence, not profitability. The catalog extraction pipeline did not independently backtest these records. Its separate selected testing ledger does not validate the wider corpus. Rules, labels and parameters can be incomplete or wrong; consult the original source and its reuse terms.

No endorsement, ownership claim or source-code reuse permission is implied.

## Extraction warnings

- Stop loss: Auto_SL = true: distance between order open price and Parabolic SAR point * SL_koef; Auto_SL = false: fixed SL parameter in points
- Take profit: Auto_TP = true: Stop Loss * TP_koef; Auto_TP = false: fixed TP parameter in points
- Position sizing: lot calculated as % of deposit based on Risk parameter and Stop Loss; if Martin = true, risk of next trade multiplied by Koef after loss
