pub fn normalize_qot_sub_market(market: i32) -> Option<i32>Expand description
Normalize Qot_Sub market input.
Qot_Sub is a user-facing API and historically accepted callers that sent
Trd_Common.TrdMarket enum values instead of Qot_Common.QotMarket.
Preserve that compatibility in the shared QOT domain so gateway surfaces do
not each carry their own mapping table. RegQotPush intentionally bypasses
this helper; see is_valid_qot_market.
