Learn the distinctive traits of each part of the market day. Intraday time segments contain repeating cycles that must be considered before trade execution. For example, don't chase opening hour excitement without understanding the specific risks. Early opportunities often disappear as soon as you see them. And avoid buying weakness in the last hour if price is below key support.
Time of day favors painful declines for issues near their lows near market close.
Watch the clock and become a market survivor. You'll develop an intuitive sense of how your positions will react as time responds to intraday cycles. Successful day traders recognize high probability positions that exploit individual quirks of market behavior. Focus on optimizing entry and exit. Play single direct thrusts and manage your position size to control risk.
