The reason is because all too often the price can drop and you will end up giving up that profit. Instead, as soon as I’ve reached my first profit target (if I’m risking $100, then as soon as I’m up $100), I’ll sell 1/2 my position and set my stop at breakeven. This method of scaling out ensures small profits on all trades that move in your favor, giving you a better percentage of success.
Based on particular setups, any trading system can be used for the purposes of scalping. In this regard, scalping can be seen as a kind of risk management method. Basically, any trade can be turned into a scalp by taking a profit near the 1:1 risk/reward ratio. This means that the size of the profit taken equals the size of a stop dictated by the setup. If, for instance, a trader enters his or her position for a scalp trade at $20 with an initial stop at $19.90, the risk is 10 cents. This means a 1:1 risk/reward ratio will be reached at $20.10.
The most significant benefit of intraday trading is that positions are not affected by the possibility of negative overnight news that has the potential to impact the price of securities materially. Such news includes vital economic and earnings reports, as well as broker upgrades and downgrades that occur either before the market opens or after the market closes.
A trader can measure their performance as a percentage of the trading channel width. The perfect trade would be buying at the bottom channel line and selling at the top channel line, which would be a 100% performance. If a trader captured one-half of the channel, it would be a 50% performance. The goal is to continually increase the performance percentage of the average winning trade.
