automated trading

Hello there,

Complete newbie here :)

I'm looking for a way to set a system to alternately buy or sell contracts (forex) with the same contract size, stop and limit, every 5 minutes for example.

Just playing around with trading ideas really, and not looking for any analytical capability - just a system to automate extremely simple, repetitive orders.

Any advice would be much appreciated!

Cheers,
Naggastos
