as far as i can judge, you need web-based trading software. you can try saxo webtrader, for example. as for me, i'm using protrader web.
hope, it will help =)
i can recommend you Ninja (ninjatrader.com) or Protrader 2 (protrader.net). both these platforms allow trading futures and stocks and have a lot of possibilities for automated trading and technical analysis. as for me Protrader is more convenient, but you can try demo to make your own opinion.
this feature is in mt4 and also i saw it in protrader. you search on the forums, related to these platforms or download demo to try. as far as i can judge protrader has no forum, but a lot os information about it is on protrader.net
