Quote from oilfxpro:
Day trading suffers from spread costs which make a large % of profits , small profits /larger losses , not enough big trends intra day , noise and wind technical analysis , plenty of false breakouts and reversals , high volume trend breakdowns ,much false volatility due to economic news etc
There are plenty of false breakouts and reversals on the higher time frames too, the only difference is that you don't suffer from exceptionally high frictional costs when you trade the higher time frames.
Take the ES for example, you lose 2 ticks (spread) + comm + potential 1 tick slippage each time you enter an intraday trade, its nearly impossible to overcome such costs unless your win rate is extremely high, or at least its impossible unless we get 2-3 times the trading range we are getting now.
