When there are higher low points along with stable high points, this suggests to traders that it is undergoing a period of consolidation. Consolidation usually takes place before a major price swing (which in this case, would be negative). Learning about triangle trading and other geometric trading strategies will make you a much better swing trader.
Take profits near the upper channel line. If the market is strong, you can wait for the channel line to be hit. If it's weak, grab your first profit while it's still there. What if a strong swing overshoots the channel line? An experienced trader may shift his tactics and hold a little longer, perhaps until the day when the market fails to make a new high. A beginning trader is better advised to take profits after the channel line has been hit as it's important to learn to take profits in accordance with one's trading plan.
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.
There is no special qualification required to become a day trader. Instead day traders are classified based on the frequency of their trading. FINRA and NYSE classify day traders based on whether he or she trades four or more times during a five-day span, provided the number of day trades is more than 6% of the customer's total trading activity during that period or the brokerage/investment firm where he or she has opened an account considers him a day trader. Day traders are subject to capital and margin maintenance requirements.
Smaller moves, easier to obtain - A change in price results from imbalance of buying and selling powers. Most of the time within a day, prices stay stable, moving within a small range. This means neither buying nor selling power control the situation. There are only a few times which price moves towards one direction, i.e. either buying or selling power controls the situation. It requires bigger imbalances for bigger price changes. It is what scalpers look for - capturing smaller moves which happen most of the time, as opposed to larger ones.
The systems by which stocks are traded have also evolved, the second half of the twentieth century having seen the advent of electronic communication networks (ECNs). These are essentially large proprietary computer networks on which brokers can list a certain amount of securities to sell at a certain price (the asking price or "ask") or offer to buy a certain amount of securities at a certain price (the "bid").

Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
