Question of the day...
Why does a daily trend fail?
Trading should always occur within the context and setting of the next higher time frame. For example, the weekly trend is 5 times stronger than the daily. The monthly trend is 22 times stronger than the daily.
If the daily trend is positive but both the weekly and monthly are negative, the lifespan of the daily is clearly limited because the stronger trend forces are pressing down on the daily time frame and limiting its progress. That is why the daily fails.
Upon achieving a positive weekly (and later, a monthly) overall trend power is enhanced. This allows for a longer duration in the trade and a larger potential profit.
If one truly understands this simple time frame trend concept, one is already miles ahead of the crowd.
Simple trading logic and in plain sight all along.
