As my first spread betting provider, my experiences were virtually the same as ORCHARD.
The only other significant points I would make are :-
1. They run a unique TRADING ACADEMY for first timers. This runs for 8 weeks during which you get to trade for 1p stakes on anything. Plus you get a weekly pamphlet explaining each trading section, golden rules, etc. At the end of the 8-week period, your minimum online stake ups to 50p [phone trades are higher].
However, the pamphlets are only a guide to using the site. You'll still have to gain market knowledge elsewhere.
2. They offer the lowest stakes I can find [50p/point on internet positions]. The 1p 'academy' stake was great as an introduction to actual trading.
3. The site gives quick/easy access to prices without having to log in. I find this is good while at work, as actual gambling is prohibited.
4. Online order placing and stop-loss access is a big improvement, but is currently only active when markets are open. I believe they plan to allow access outside market hours in the future.
Whilst maybe not the cheapest spreads around, but I'd say one of the best for new traders.
