Your own TradingView feeds, trading your own connected exchanges only. Each source = one indicator, with its own webhook URL — paste it into the indicator’s TradingView alert; the alert text can be anything once you fill its Mapping. Coin optional: blank = the source trades whatever coin the alert names (via {{ticker}}). Exchange picks which of your accounts receives (all / one / dry-run). Native JSON ({"action":"buy"}) also works without a mapping. Prefer trades picked for you? Subscribe on the Signal page instead.
