请问 期权交易模块，如何支持原油数据，
CHAIN_UNDERLYING_MAP: dict = {
# ETF Options
"510050_O.SSE": "510050",
"510300_O.SSE": "510300",
"159919_O.SZSE": "159919",
# Futures Options
"IO.CFFEX": "IF",
"HO.CFFEX": "IH",
"i_o.DCE": "i",
"pg_o.DCE": "pg",
"m_o.DCE": "m",
"c_o.DCE": "c",
"cu_o.SHFE": "cu",
"ru_o.SHFE": "ru",
"au_o.SHFE": "au",
"SR.CZCE": "SR",
"CF.CZCE": "CF",
"TA.CZCE": "TA",
"MA.CZCE": "MA",
"RM.CZCE": "RM",
"sc.INE": "SC",
"sc_o.INE": "SC",
}
之前没有SC，我自己加了一下，但是解析出来的数据是错误的，最后得出来的
chain_underlying_map {'sc2209.INE': 'sc2209.LOCAL', 'sc2210.INE': 'sc2210.LOCAL'}, underlying_symbol:sc2210.LOCAL为什么我把BASE的 CHAIN_UNDERLYING_MAP 加了 "sc.INE": "SC", 但是最后，它没找到期权合约。 代码上，我一时间 也不确定该检查哪个
感觉是 OptionEngine 的 portfolios 没对嘛?
