If your decisions come from a chart alert, use a strategy. If they come from you trading one account by hand, use the copier — on a leader whose broker copies hand trades. Nothing stops you running both, on different accounts.
breakeven or update alert moves the followers' stops itself, each to its own entry on a breakeven — being proven on Tradovate and switched on per account, and not on other brokers yet; see Moving a stop by alert.
