I have been using these guys for a few weeks and they seem to have pretty good signal. I have been using the GBP/USD package.
Signals are provided every 4 hours. 6am, 10am, 1pm, 5pm
Information is included on whether to go long/short
Where to put your stop
When to
take profit (this is always 49 pips)
So far the results have been encouraging, they are not generating heaps of money, but are not doing too badly, a slow trickle would be the best way to put it.
