The unglamorous part of automation
Copy trading looks simple until two terminals argue about who is allowed to trade. Algo stacks fail more often from ownership and identity mistakes than from indicator code.
Same-Login guard
If a Master publisher and a Slave subscriber share one broker login, you can create a feedback loop: the slave mirrors the master, the master republishes the slave, and sizes explode. TradeEcho slaves refuse that configuration (BLOCKED). That is intentional.
Mirror Ownership lease
A second slave on the same path + broker login can steal the lease. The previous instance goes STANDBY and must not keep trading. Prefer one trading instance per login per copy path.
Operator checklist
- Distinct broker logins for master vs slave
- Unique account labels per terminal
- Different magics for MT5 copy vs TV slave when both run
