# Each name is an .ini in the fleet terminal's data dir. For each run this:
#   * closes any running terminal64 (a second launch on the same data dir is
#     silently swallowed by the running instance - the config never runs)
#   * launches with /config:<BACKSLASH path> (a forward-slash path falls back to cwd)
#   * checks the line after "launched with <ini>" is "automatic testing started"
#     (the process exit code says nothing about whether the test ran)
#   * waits for the EA's journal and copies it to dipz_trades_<name>.csv
