http://www.finra.org/industry/interpretations-margin-rule
“day trading” means the purchasing and selling or the selling and
purchasing of the same security on the same day in a margin account ...
4210(f)(8)(B)(ii)/01 试图进一步澄清，但还是没解释清楚
Multiple Purchases and Sales
If a customer enters an order to purchase a security and sells the
same security within the same day, but for reasons beyond the
customer’s control e.g., price, the purchase was executed in smaller
blocks, it will be considered as one day trade. However, the member
must be able to demonstrate that it was the customer’s intent to
execute one day trade. This will also apply to when a customer
enters a sale order and buys the same security within the same day.
In addition, the trades would have to have been executed in
sequential order.
One purchase and several subsequent sale transactions of the same
security, where the sales were executed in sequential order within
the same day, shall constitute one day trade. One sale and several
subsequent purchases of the same security, where the purchases were
executed in sequential order within the same day, shall also
constitute one day trade.
Scottrade的定义更严格准确一些，直接数opening transactions：
https://www.scottrade.com/knowledge-center/investment-education/trading-
topics/day-trading/counting-day-trades.html
Any opening transaction closed out in part or in full
in the same day is counted as a day trade.
比如下列操作序列算两次day trades：
1. open position for 100 shares
2. open position for 200 shares
3. close (position 1 in full and position 2 in part) for 150 shares
但这个序列我今天肉身在Robinhood上试了，仅仅记了一次。
可见FINRA并没有完全定义清楚，不同券商有不同解释？ |
