In my experience as a day trader, the initial moments after the market opens are crucial for setting your trading bias. By quickly analyzing where the market opens relative to yesterday’s close and the volume profile's value area low (VAL) and value area high (VAH), you gain immediate insight into market sentiment. For example, if the market opens above yesterday’s value area high and yesterday’s close was also above this range, it suggests bullish momentum and the potential to take long positions near that value area high. Conversely, if the market opens below the value area low and yesterday’s close was also outside this range, short trades might have a higher probability of success. The volume profile is especially useful here. It helps to identify price levels with the most trading activity from the previous day, providing natural support or resistance. Using this information as reference points for entry and exit minimizes risk. An additional tip I’ve found beneficial: always confirm your initial bias by monitoring how the price behaves in the first 5 seconds to 15 minutes. This period will often highlight whether your directional assumption holds or if there’s early market rejection. Keeping this routine helps avoid many losing trades caused by guessing or waiting too long. It brings discipline and confidence to your trading day because you’re basing decisions on objective market data rather than emotions. In summary, combining the first 5 seconds market open observation with volume profile data and yesterday’s close and value areas creates a strong foundation for daily trading strategies, helping manage risk and seize high-probability opportunities.
