Chowclown - I use the 34 ema on the 1 min chart as well as an aid to entry, but I am not a scalper by nature - doesn't suit my trading style - and to be brutally honest with myself, I'm not very good at scalping! . So I also use the 100 ema, as suggested by chartman for the Dow, which also approximates to the 34ema on the 3 min chart.
Fluke - apart from occasional trades on the ftse100 future, I no longer follow UK shares closely - tending to trade the US for all the reasons pointed out elsewhere on this BB. Probably a pity in some ways because there is no doubt that there have been some good profits to be made in the UK in the last 3 months in particular.
Agincourt - Fine. I guess it just depends on your timeframe, and how tight you like to keep your stops. I have a tendency to set them too tight.
