Your strategy library — each source is one indicator saved as a reusable feed, with its own webhook URL and its own alert Mapping. Paste the URL into the indicator’s TradingView alert; the alert text can be anything once the Mapping is filled. Coin optional: blank = it trades whatever coin the alert names (via {{ticker}}). Routing = tick each exchange this feed may trade (tick several to share one webhook across accounts; nothing ticked = it routes nowhere). A feed only ever trades a container that subscribed to it — bind it inside a container on the Portfolio page, so every trade stays inside the ledger and the URL alone can do nothing.
