Futures are a contract that match up a buyer and seller at a specific price, with the buyer agreeing to pay that price for the asset when the contract expires in the future. The seller is agreeing to deliver the asset, like oil for example, to the buyer when the contract expires. Day traders are never required to deliver or pay for the actual asset, because all positions are opened and closed within the day (no open obligations). Profits are losses are based on the prices the contract is opened and closed at.

FX 1-minute scalping is a day trading strategy, as it involves opening a certain position, gaining a few pips, and then closing the position afterward. It is one of the most basic and resourceful trading strategies. The main aspect of Forex scalping is quantity. It is not unusual for traders to place more than 100 trades a day. For this reason, it is important to pick a broker with the smallest spreads, as well as the smallest commissions.

Sincere interviewed professional day trader John Kurisko, Sincere states, Kurisko believes that some of the reversals can be blamed on traders using high-speed computers with black-box algorithms scalping for pennies. “That’s one of the reasons many traders get frustrated with the market. The timing is not like it used to be, and many of the old rules don’t work like before.” [2]
A basic EMA crossover system can be used by focusing on the nine-, 13- and 50-period EMAs. A bullish crossover occurs when the price crosses above these moving averages after being below. This signifies that a reversal may be in the cards and that an uptrend may be beginning. When the nine-period EMA crosses above the 13-period EMA, it signals a long entry. However, the 13-period EMA has to be above the 50-period EMA or cross above it.
Swing traders usually go with the main trend of the stock. But some traders like to go against it and trade the counter trend instead. This is known as “fading,” but it has many other names: counter-trend trading, contrarian trading, and trading the fade. During an uptrend, you could take a bearish position near the swing high because you expect the stock to retrace and go back down. During a downtrend to trade the fade, you would buy shares near the swing low if you expect the stock to rebound and go back up.
First, find the lowest point of the pullback to determine the “stop out” point. If the stock declines lower than this point, you should exit the trade in order to limit losses. Then find highest point of the recent uptrend. This becomes the profit target. If the stock hits your target price or higher, you should consider exiting at least a portion of your position, to lock in some gains.
Scalpers need to be disciplined and need to stick to their trading regimen very closely. Any decision that needs to be made should be done so with certainty. But scalpers should also be very flexible, because market conditions are very fluid and if a trade isn't going as expected, they'll need to fix the situation as quickly as possible without incurring too much of a loss. 
There are a variety of methodologies to capitalize on market swings. Some traders prefer to trade after the market has confirmed a change of direction and trade with the developing momentum. Others may choose to enter the market on the long side after the market has dropped to the lower band of its price channel—in other words, buying short-term weakness and selling short-term strength. Both approaches can be profitable if implemented with skill and discipline over time.
Scalping in this sense is the practice of purchasing a security for one's own account shortly before recommending that security for long-term investment and then immediately selling the security at a profit upon the rise in the market price following the recommendation.[5] The Supreme Court of the United States has ruled that scalping by an investment adviser operates as a fraud or deceit upon any client or prospective client and is a violation of the Investment Advisers Act of 1940.[6] The prohibition on scalping has been applied against persons who are not registered investment advisers, and it has been ruled that scalping is also a violation of Rule 10b-5 under the Securities Exchange Act of 1934 if the scalper has a relationship of trust and confidence with the persons to whom the recommendation is made.[7] The Securities and Exchange Commission has stated that it is committed to stamping out scalping schemes.[8]
Liquidity - The liquidity of a market affects the performance of scalping. Each product within the market receives different spread, due to popularity differentials. The more liquid the markets and the products are, the tighter the spreads are. Some scalpers like to trade in a more liquid market since they can move in and out of large positions easily without adverse market impact. Other scalpers like to trade in less liquid markets, which typically have significantly larger bid-ask spreads. Whereas a scalper in a highly liquid market (for example, a market maintaining a one-penny spread) may take 10,000 shares to make a 3 cent gain ($300), a scalper in an illiquid market (for example, a market with a 25 cent spread) may take 500 shares for a 60 cent gain ($300). While there is theoretically more profit potential in a liquid market, it is also a "poker game" with many more professional players which can make it more difficult to anticipate future price action.
The common use of buying on margin (using borrowed funds) amplifies gains and losses, such that substantial losses or gains can occur in a very short period of time. In addition, brokers usually allow bigger margin for day traders. In the United States for example, while the initial margin required to hold a stock position overnight are 50% of the stock's value due to Regulation T, many brokers allow pattern day trader accounts to use levels as low as 25% for intraday purchases. This means a day trader with the legal minimum $25,000 in his account can buy $100,000 (4x leverage) worth of stock during the day, as long as half of those positions are exited before the market close. Because of the high risk of margin use, and of other day trading practices, a day trader will often have to exit a losing position very quickly, in order to prevent a greater, unacceptable loss, or even a disastrous loss, much larger than her original investment, or even larger than her total assets.
The following are several basic trading strategies by which day traders attempt to make profits. In addition, some day traders also use contrarian investing strategies (more commonly seen in algorithmic trading) to trade specifically against irrational behavior from day traders using the approaches below. It is important for a trader to remain flexible and adjust techniques to match changing market conditions.[11]
Once you have a specific set of entry rules, scan through more charts to see if those conditions are generated each day (assuming you want to day trade every day) and more often than not produce a price move in the anticipated direction. If so, you have a potential entry point for a strategy. You'll then need to assess how to exit, or sell, those trades.
