Fetch a signal from YOUR backend

  action: "hold" | "buy" | "sell";
  asset: string;
  confidence: number;
}

export default function createExampleSignal(): StrategyPlugin {

  const vaultId = process.env.VAULT_ID;

  if (!vaultId) throw new Error("exampleSignal: VAULT_ID not set");

  const signalUrl = process.env.SIGNAL_URL ?? "https://your-backend.com/signal";

  return {
    name: "exampleSignal",
    vaultId,
    triggers: [{ kind: "cron", everySeconds: 5 }],

    async decide(ctx) {

      const res = await fetch(signalUrl);

      const signal = (await res.json()) as Signal;

      if (signal.action == 'hold') return [{ kind:'noop', reason: 'hold'}]

// insights we can take from this example:

// You can connect an external backend to handle more granular decisions in other languages and keep only execution here. Separation between intelligence/quant code and execution.
