买了一些BSTI玩，买入前买入后价格都是在$10.75-10.85左右根据Robinhood自己给
的信息。为什么我的买入价格确是$11.00? 这个很坑爹啊。

我Robinhood肯定是比价格高1分钱的，比如10.00的股最后买入价都是10.01

有可能你买的那个时间段真实价格到过11. 我遇到实际买入价比RB显示价格低2-3分钱
的,当然也有时候会高一点点

Robinhood 还敢用market order？他家的所有market order都是瞬时limit order，
limit price是在你的bid price上加了5%。所以你买到的基本都贵很多。
Never use market order with robinhood.

Front trading啦。
这个普遍存在于几乎所有的券商，except IB with 30 USD purchase NBBO service。
流动性好的股票、比如AAPL，散户意识不到，流动性差的，有没有quote几个交易所，
怎样的routing，就体现出了价值。
大券商比如fidelity肯定也偷偷front trading，你资金量大一点不同的平台，会有好
一点的routing，也会favor一点。你亏的少。
同时间schwab价格就更好。
小一点的比如死掉了的option house，价格就不友好。
当然了，你就几千1万的，这点差价就忽略吧。
最近看好多文章讲ETF买卖的，都提到交易费可以忽略，管理费要pay attention。管理
费都是万分之几。
所以将交易费5-10元贵不贵，和你的资金有关，很多人只有2000块炒股，成交价差一点
换5块钱free，make sense。
以前option house也不能access过，大broker基本没发生过。

Robinhood receives payments from some marker makers,
with whom it signed contracts, for routing order flows to them.
This is a pretty standard practice adopted by all brokers,
and it constitutes a major portion of Robinhood's income.
In fact, all brokers have incentives to route your orders
to whichever marker makers that will pay them the most,
in order to maximize their profits, probably at the expense
of not giving you the best "price improvement." Well, I
guess Robinhood didn't promise any price improvements
like other brokers to whom you pay commissions.
(Of course, they have to comply with the NBBO rule, that is,
your order must not be filled at a price worse than the NBBO
bid-ask spread. If you find any NBBO violations, you could
certainly file a complaint to SEC against your broker.)
Other possible sources of revenues in Robinhood's business
model could include: liquidity rebates from exchanges (for
non-marketable orders), interests on your deposited cash,
lending margin or paid margin programs (like their Robinhood
Gold membership), etc. But the payments from marker makers
mentioned above should constitute the majority and the most
consistent source of revenue flow for them.

Yes, I guess they do not route market orders to the exchanges,
or they may be charged for taking the liquidity off the exchanges.
Since they do not charge commissions on their clients, they do
not have incentives to create internal dark pools, like IB and a few
other infamous brokers, to trade amongst or against their clients.
They are likely to route your orders to their contractual marker
makers first, in order to receive payments for the order flow.
They then route your order to public exchanges only if none
of their contractual marker makers would like to fill your order.
And when they do this, they may have incentives to convert
market orders into non-marketable limit orders, to avoid being
charged by exchanges for removing liquidity.
Although software bugs may exist, I do not believe Robinhood
intentionally violates NBBO rules.
Of course, this is purely my speculation based on my limited
understanding on order routing and broker business.
