Prop platforms, on the other hand, are customized platforms developed by large brokerages to suit their specific requirements and trading style.
When thinking about the mindset of investors, The Great Crash 1929 by J.K.Galbraith (reviewed here) should also be required reading. Typically, any sustained fall in prices - known as a bear market - is very destructive to wealth. However, as Galbraith explains wonderfully, each bear market is unique and is a reflection of the bull market that came before it. The book explains a great deal about the feedback loops that can exist when prices rise and fall as more people are either sucked into or forced out of holdings. It is the reference work about a very important slice of Wall Street history.
The list of stock brokerage firms is updated throughout the year.

The most feared words on any stock exchange are margin call. A margin call is made when a position is losing money and more money is required by the broker to keep the trade open.

Volatility can be either a blessing or a curse, but if you have too much leverage, it can break a trader.
While that may sound like outdated advice, in late 2012, an American marketing executive explained how he had turned $20,000 into $2 million during the recession. Chris Camillo explained that Wall Street is quite homogenous and tends to be behind the curve on trends involving females, young people and those on low incomes. Camillo invested in stocks that anyone could have, he just spotted trends before the investment bankers did and was able to make some very sizable profits.
TD Ameritrade focused its 2019 development efforts on its most active clients, who are mobile-first – and in many cases, mobile-only. TD Ameritrade’s thinkorswim mobile platform has extensive features for active traders and investors alike. The workflow for options, stocks, and futures is intuitive and powerful. You’ll find lots of bells and whistles that make the mobile app a complete solution for most trading purposes, including streaming real-time data and the ability to trade from charts.

Finally, keep in mind that if trading on margin—which means you're borrowing your investment funds from a brokerage firm (and bear in mind that margin requirements for day trading are high)—you're far more vulnerable to sharp price movements. Margin helps to amplify the trading results not just of profits, but of losses as well if a trade goes against you. Therefore, using stop losses is crucial when day trading on margin.

Experienced investors such as Buffett eschew stock diversification in the confidence that they have performed all of the necessary research to identify and quantify their risk. They are also comfortable that they can identify any potential perils that will endanger their position, and will be able to liquidate their investments before taking a catastrophic loss. Andrew Carnegie is reputed to have said, “The safest investment strategy is to put all of your eggs in one basket and watch the basket.” That said, do not make the mistake of thinking you are either Buffett or Carnegie – especially in your first years of investing.

To make comparisons between companies, sectors and markets a little easier, there are a number of mathematical models used. The most common and often the most helpful is the P/E ratio. The Price to Earnings ratio takes the share price and is divided by the earnings per share. It is possible to calculate this using past earnings, projected future earnings and with all sorts of moving averages ;-) Therefore, this is one number that it is vital for any investor to know and understand.
