That's the answer to question 1) above, correct? Unfortunately it does not work for me, error as described above ("!Can't initialize MT4 bridge!"), no entries in both MT4 EA logs. MT4s are in different folders (2 different brokers, so different installation folders by default). It even fails if I close the other MT4 instance and the other Zorro instance completely. So there seems to be an issue connecting to the MT4 instance which I installed 2nd. No problems connecting to the 1st...
Assuming we can somehow fix problem 1) - What about question 2), same strategy with 2 MT4 instances and 2 accounts?
