I trade a daily method and a 5 min method..whilst you put in less time on the daily...over a week time frame it would be very little difference between the two as far as the gain in pips.....Of course the profit would be far greater on the short term as you can open multi lots and close then within a shorter time frame.....
The other disavantage with the longer time frame would be the account size required to handle the drawdowns...
I belive a good short term method has its place as you can trade waiting for a setup on the daily ( which may only come one's a week at best)...
And please dont ask me for my 5 min method...as i have posted several allready on this forum..
