i have red some of forum topics and still have bugs about why broker's not allowed the service. Some because their server is not updated and some they just won't enable it.
My suggest that metaquotes should optimize brokers. It's nothing without brokers support the service.
For example :
Option to broker the signals from specific brokers can only follow by the clients on signal provider have.
Yes, the competition is more open now than before. Everyone can see what benefit does other broker has to offer, from one broker to another - all in one place.
Some broker probably will see this as an opportunity to sell their managed account though signal service - maybe something like "Signal ABC is free (save $$$ per month) if you open account with broker XYZ".
Some broker will probably just do nothing and can't compete at all.
What else can we say ? maybe its OK to say this : that there's always 'victim' in a new technology. I bet, right now, you using DVD to watch movie instead using VHS/Betamax, or using CD instead cassette recorder, iPod instead of Walkman, and sending your emails using computer instead typewriter., sms instead post office, ... heck your mobile phone is actually also a digital camera, an FM radio, mp3-audio player, an internet browser with opmin (opera mini) and in some countries its actually a payment device.
Don't worry, be happy, people do survive.
