Pine Script 3Commas V2 Upgrade

My TradingView strategy is written entirely in Pine Script and, up to now, has been firing its buy-and-sell webhooks to the legacy 3Commas V1 endpoint. With 3Commas having moved to V2, none of those alerts reach my crypto bots anymore, so the script needs to be refactored to speak the new language.

What I need is straightforward: replace the old alert blocks with the correct V2 webhook structure and create the corresponding order-entry payloads so the bots can place and close cryptocurrency trades just as they did before. The core strategy logic, indicators and risk rules stay exactly the same; only the alert section and any helper functions that format the JSON must change to meet the new 3Commas V2 specification.

Deliverables I can test right away:
• A revised Pine Script file ready to paste back into TradingView.
• Sample V2 alert JSON for both long and short entries, take-profit and stop-loss.
• A quick note showing where to drop my secret key and how to map the pair placeholder for any crypto symbol.

Once I can fire a few test alerts from TradingView and see them land correctly in my 3Commas account, the job is complete.
