With the combination of market profile and market internals you can usually get a very good indication of the trading environment shortly after the open. Market Profile is the process of using statistics to define the previous days fair price. In general, a market that breaks out and/or finds S/R outside the
value area (with market internals behind it) will trend in that direction looking for the new fair price (many times previous
value areas). A market currently inside the
value area will move from one side to the other until interest is found outside, usually with increasing internals in that direction. Of course this is based off a normal distribution day. In my opinion you not only need the price action (daily candle, market profile, opening range, etc) but also the market internals to make educated decisions about trading conditions.
