In esports, you review your VODs, tag mistakes, drill specific weaknesses, and measure improvement week over week. In retail trading, almost nobody does any of it. Mettle is the feedback loop I wanted for my own trading, shipped.

Yes. Paste your Pine in Settings → Indicators. You keep the source, Mettle catalogs it and wires your TradingView alerts through to plays + journal + coaching. The Master tier is for traders who want to generate watermarked Pine on demand and publish via the vault. Not a requirement.
Indicators the Workbench generates publish to your TradingView as invite-only private scripts. You use them on your charts but the Pine source stays licensed to us. If you cancel, the invite is revoked. This keeps indicator generation sustainable. Indicators you import yourself aren't vaulted. They're yours.
