Markets move higher, markets move lower. The question worth continually posing is, "Is the market getting stronger or weaker?" This is a meaningful question because a market that moves higher can be getting weaker and a market that moves lower can be getting stronger. Perhaps momentum is waning. Perhaps fewer shares are participating in the move. Very, very often markets will get weaker before they put in a top and will get stronger before a bottom is in place. Is the dollar index moving lower? How many dollar crosses are actually participating in that move? Are stocks moving higher? How many sectors are driving the move? Oil is moving higher. Are we seeing a growing number of contracts trading at offer vs. bid price, or are we seeing size starting to hit bids?
