first, you must know
investors and not day traders want to know whether it is a bull or bear market.
day traders want to know these :
1. dead market - not tradable because the market is not moving
2. choppy market - high chance of losing $$$
3. trendy market - easy to trade. lookout for continuation and
reversal signals.
unfortunately,
most of the time, the market is dead or choppy.
so be alert and wait patiently for the trendy market.
But then you must be able to identify these 3 types of market.
An experienced trader can handle all those markets, with the caveat that the "dead" market has to be moving a little, say 3 times the spread plus comms. If by "dead" you mean the trend is flat but the range is good that can be profitable you can often get a few bounces. It always ends in a loosing trade but is profitable overall.
