How can I promote my Expert?
Can I put adds in Google and Facebook?
Give it away for free
Don't give it away for free !
Give people a free month to use it and then if they like it, they will rent it longer, or even buy it.

The expert is in MQL5.com
Rent - month = 10 USD
I put a signal but the system archive it.
I will open a new account soon.
Keep selling expensive do not let others think you are cheap.
