Safety Price limits

Dreamcash adds an extra safety rule to reduce price manipulation:

The mark price is not allowed to move too far away from the most recent external oracle (spot) price. The maximum gap is ± (1 / max leverage).

In an instance of a Dreamcash markets with 20× max leverage, that means the mark is capped to stay within ±5% of the last external oracle price — in both normal and off-hours sessions.
