//| MockTick: the atomic unit of synthetic market data. |
| |||
//| |
| |||
//| Each field is independently controllable so test scenarios can |
| |||
//| vary one dimension at a time (spread spike, price gap, error |
| |||
//| injection) without coupling to the others. |
| |||
//| |
| |||
//| Design note: spread_points is separate from the bid/ask delta |
| |||
//| to allow scenarios where spread is the variable under test, |
| |||
//| independently of the price levels. |
