Why make it complicated? Just follow the trends. Pullbacks and trading ranges does not mean a bear market. It is just areas where buyers get in.
Agree, and that strategy requires ZERO predictions. Just go with the flow.
It works more times than it doesn't in markets that are flowing. As to what a flowing market looks like - look at the chart, it should be instantly recognisable. If it's not, either look at a different market or change the time-period.
How/when/where to take profits is the hard part. One area to be on the lookout for in a flowing market is when the price goes out of character, ie the previous moves up/down have sort of been similar but then comes an upmove (assume up-flow) that is far greater than the previous up-moves. That's the out of character price action and it's a very good place to think about covering.
