ECNs and exchanges are usually known to traders by a three- or four-letter designators, which identify the ECN or exchange on Level II stock screens. The first of these was Instinet (or "inet"), which was founded in 1969 as a way for major institutions to bypass the increasingly cumbersome and expensive NYSE, and to allow them to trade during hours when the exchanges were closed. Early ECNs such as Instinet were very unfriendly to small investors, because they tended to give large institutions better prices than were available to the public. This resulted in a fragmented and sometimes illiquid market.
A stop-loss order is designed to limit losses on a position in a security. For long positions, a stop loss can be placed below a recent low, or for short positions, above a recent high. It can also be based on volatility. For example, if a stock price is moving about $0.05 a minute, then you may place a stop loss $0.15 away from your entry to give the price some space to fluctuate before it moves in your anticipated direction.
The goal of swing trading is to capture a chunk of a potential price move. While some traders seek out volatile stocks with lots of movement, others may prefer more sedate stocks. In either case, swing trading is the process of identifying where an asset's price is likely to move next, entering a position, and then capturing a chunk of the profit from that move.
Trading: Spotting the trend and momentum comes in handy for a scalper who can even enter and exit briefly to repeat a pattern. A novice needs to understand the market pulse, and once the scalper has identified that, trend trading and momentum trading can help achieve more profitable trades. Another strategy used by scalpers is countertrend. But beginners should avoid using this strategy and stick to trading with the trend.
Some of the common mistakes that scalpers make are poor execution, poor strategy, not taking stop-losses, over-leveraging, late entries, late exits and overtrading. Scalping generates heavy commissions due to the high number of transactions. A per-share commission pricing structure is beneficial to scalpers, especially for those who tend to scale smaller pieces in and out of positions.
In either of the two market extremes, the bear market environment or raging bull market, swing trading proves to be a rather different challenge than in a market between these two extremes. In these extremes, even the most active stocks will not exhibit the same up-and-down oscillations as when indexes are relatively stable for a few weeks or months. In a bear market or bull market, momentum will generally carry stocks for a long period of time in one direction only, thereby confirming that the best strategy is to trade on the basis of the longer-term directional trend.
Successful traders have to move fast, but they don't have to think fast. Why? Because they've developed a trading strategy in advance, along with the discipline to stick to that strategy. It is important to follow your formula closely rather than try to chase profits. Don't let your emotions get the best of you and abandon your strategy. There's a mantra among day traders: "Plan your trade and trade your plan."
