What is Opening Range Breakout (ORB)?
Opening Range Breakout (ORB) is a day trading strategy that focuses on the first few minutes of market trading to establish a high and low range. Traders then wait for price to break above the high or below the low of this opening range, entering trades in the direction of the breakout to capture early momentum moves.
The strategy is based on the premise that significant price movements often occur when stocks break out of their opening range, as this indicates strong buying or selling pressure that may continue throughout the trading session.

Day Trading Risk Disclaimer
Opening Range Breakout trading involves substantial risk and is not suitable for all investors. Day trading can result in significant financial losses, and many day traders lose money. The high volatility at market open can cause rapid and substantial losses. Past performance does not guarantee future results. The leveraged nature of day trading can amplify both gains and losses. Only trade with capital you can afford to lose entirely. Consider consulting with qualified financial professionals and thoroughly educate yourself about the risks before engaging in day trading activities.
