I have some buy/sell arrow based MT4 indicators. I don't want to share these indicators, but only the arrows/alerts. I need someone to produce a solution which consists of three parts.
1. Client indicator which connects to server.
2. Script on server's MT4 which fetches arrows in real-time and immediately sends them to currently connected clients.
3. Ability for me to see currently connected users. I.e. I must be able to add and delete users from a control panel, based on their account numbers, and I should be able to see their IP addresses.
I don't want the client indicator to check for latest arrows every X seconds, because this puts load on the server. Rather, I just want the server to send out the arrows to currently connected clients as soon as the arrows appear.
