New to the forum, so hello one and all

is this a common trading strategy? Relatively new to spread betting, been doing it for 6 months and am feeling a little more confident. (I realise this comes with time, and experience, both good and bad).
This last 5 days I've been in and out of trades daily, throughout the day and snatched close to 400 points (I've made a lot of short trades, time held from a few seconds to maybe 15 minutes maximum, I'm lucky in that I am desk based at work 95% of my working day. Average this week of 11 trades/bets a day). I still only do the minimum value, ?2 a point with my company.

Is this called scalping? And is it a successful way of spread betting? Genuinely interested.

Like I said, I am new to this, still extremely cautious (I'm a tight git) which I think explains my 'preference' to only have a trade/bet open for a few minutes. At present, I prefer to 'grab' (or scalp, if its called that) a few points/?'s in a few minutes rather than hold on for the longer trades.

Any opinions guys (and girls)?
