Quote from marketsurfer:
Do you think this applies to scalpers?

Well, I would not presume to tell another trader the best way to make money. The proof is in the pudding: If a scalper has found a way to make consistent profit, that is what matters.
With that said, I view the market as an ecosystem, with trading strategies comparable to animal survival strategies within a diverse environmental habitat.
Not all strategies compete with each other, just as animal survival strategies do not necessarily compete with each other - while some go head to head, others are competition neutral (relative to each other) or even symbiotic.
Going by the above metaphor, some market ecosystem niches are definitely more crowded than others. Super-short timeframes are an extremely crowded space - witness the slow death of human market makers at the hands of electronic market makers.
The highly successful day traders I know tend to combine 'hardware' and 'wetware' to monitor intra-market relationships. They watch their screens with the calm of zen buddhist monks, pulling the trigger four to six times per day. A winning trade might be held for two minutes, or it might be held for two hours, depending on what happens.
This is a different ecosystem niche than trying to battle algo-bots for ticks. I'm not saying it can't be done, but instinctively I do not favor trying to make a living in niches where institutional scale and industrial strength computing power constitute an edge.
