That doesn't work because using the same strategy twice it gave an error as it read the .trd file and then Zorro could not find the already opened trades in the other MT4. So I guess you have to do three things.
The purpose was the following. I trade a strategy in MT4 with a broker. I want to trade the same strategy in another MT4 account with another broker.

1. copy and rename the dll in the Zorro Plugin Folder
2. in the accounts.csv associate the new account with the renamed dll plugin
3. copy and rename the strategy and trade the renamed strategy with the second account.

In the two MT4 don't change any names of dll's or Zorro EA's. The two MT4 instances use the same filenames for the dll's and the EA's.

Any comments from support whether this is the correct way to do this?
