Submit #864856: GitHub wondertrader 0.9.9 Incorrect Comparisoninfo

TitleGitHub wondertrader 0.9.9 Incorrect Comparison
DescriptionWonderTrader’s TraderDD queryTrades() path incorrectly uses strncpy(buf, "1", 1) == 0 to classify DD broker trade records as open or close. Because strncpy() returns the destination pointer rather than a comparison result, trades with FID_JYLB=1 are misclassified as WOT_CLOSE instead of WOT_OPEN. During startup or reconnect trade replay, this undercounts daily opened volume in _stat_map, allowing configured ActionPolicy open-volume limits to be bypassed and enabling oversized positions.
