我的Scottrade账户显示: Buying Power (Margin): $127,490.86 Buying Power (Non-Margin): $63,745.43 Total Money Balance: -$2,075.52 可是balance并没有显示有interest charge, 请问怎样可以看自己账户是否在用margin? 个人理解目前账户已经透支 $2075.52(margin), 可是看不到 interest charge,郁闷 。。。 Buying Power (Non-Margin): $63,745.43: Does it mean that I can still purchase $63,745.43 worth of stock without paying margin interest? If it is Non-Margin, I consider it as "free loan". I am confused by Scottrade account information. 多谢指教
