Founded in , Robinhood has been credited with helping usher commission-free trading throughout the retail brokerage industry. It has seen business boom during the coronavirus pandemic as more homebound consumers took to buying and selling stocks online. The app now counts more than 13 million users. While its user-friendly and engaging service has made it appealing to millions of young customers, it has also drawn the scrutiny of critics and regulators who are concerned the company may be encouraging risky behavior in retail investors.
It also suffered a number of outages this year. Massachusetts Secretary of the Commonwealth William Galvin, the state's top securities regulator, in an administrative complaint on Wednesday alleged that Robinhood marketed itself to investors without regard for the best interest of its customers.
The complaint alleged that Robinhood used the promise of free stock trades to attract new users and strategies such as "gamification" to entice repeated use of its app. Sequoia Capital's India partners, caught out early this year by governance scandals at startup companies in its portfolio, assured investors at an April meeting in London that these "lowlights" were mostly behind it, according to three people familiar with the discussions.

Abstract Gross intraoperative assessment can be used to ensure negative margins at the time of surgery. Introduction Breast conserving therapy BCT , defined as breast conserving surgery BCS followed by radiation therapy, is one of the standard of care options for early stage breast cancer 1 , 2 , 3 , 4 , 5.
Results During the study period, gross intraoperative margin assessment was requested for patients undergoing BCS with a pre-operative diagnosis of invasive carcinoma. Table 1 Confusion matrix for gross intraoperative diagnosis versus final microscopic diagnosis. Full size table. Figure 1.

That is, you have more free margin. And if the market goes against you, then you have less equity available, and therefore less free margin. Leverage would be like the size of your engine: the bigger it is, the faster you go, but the more gas you need. Your gas tank would be like your free margin. If you go fast open a lot of trades you use up more margin. If you have a smaller engine lower leverage then you use less gas. And, of course, if you run out of gas, then your car stops — just like your forex trading stops when you run out of margin!
