この例は技術文書で見ました。 「isSync」が何に使われるのか説明できる人はいますか?
def on_bulkdatafeed(self, isSync, bd, ab): p1 = 'USDJPY' instrument_p1 = bd[p1]['instrument'] timestamp_p1 = bd[p1]['timestamp'] lastPrice_p1 = bd[p1]['lastPrice'] p2 = 'EURUSD' instrument_p2 = bd[p2]['instrument'] timestamp_p2 = bd[p2]['timestamp'] lastPrice_p2 = bd[p2]['lastPrice'] isAllDataBarSync = isSync NAV = ab['NAV']
