This might be a decent recipe for longer term trading/investing. Day traders tend to trade inside the gyrations of the market, and intraday trading allows for greater leverage to take advantage of these smaller swings.
In this scenario, prudent risk management requires a stop loss at a level where the signal that price is more likely to move one direction becomes invalidated by a new signal that price is now more likely to move the opposite direction. Why stand and defend a position in the face of a signal that the odds have shifted in favor of a position opposite your current position?
