Webhooks

TradingView webhook JSON examples for futures strategy alerts

Educational payload patterns for connecting chart strategy alerts to MimikTrader. TradingView is a separate product; MimikTrader is not affiliated with TradingView, Tradovate, or any prop firm. For step-by-step UI setup, see the webhook strategies help guide.

Baseline market entry

Use strategy placeholders, not indicator plot text. TradingView fills these when the alert fires.

{
  "action": "{{strategy.order.action}}",
  "symbol": "{{ticker}}",
  "quantity": "{{strategy.order.contracts}}",
  "price": "{{strategy.order.price}}",
  "position": "{{strategy.market_position}}",
  "id": "{{ticker}}-{{strategy.order.id}}-{{time}}"
}

Entry with bracket overrides

Overrides only apply when the matching take-profit or stop override is enabled on the MimikTrader strategy. Tick offsets and absolute prices are both supported.

{
  "action": "buy",
  "symbol": "{{ticker}}",
  "quantity": "1",
  "takeProfit": { "ticks": 40 },
  "stopLoss": { "ticks": 20 },
  "id": "{{ticker}}-long-{{time}}"
}

{
  "action": "sell",
  "symbol": "{{ticker}}",
  "quantity": "1",
  "takeProfit": { "limitPrice": 5325.00 },
  "stopLoss": { "stopPrice": 5280.00 },
  "id": "{{ticker}}-short-{{time}}"
}

Limit, stop, and stop-limit entries

Non-market entries need a price. orderType applies to entries when entry override is enabled; it is ignored on close and flatten so a stray field cannot turn a flatten into a resting order.

{
  "action": "sell",
  "symbol": "{{ticker}}",
  "quantity": "1",
  "orderType": "stop",
  "price": "{{close}}",
  "id": "{{ticker}}-stop-entry-{{time}}"
}

Close vs flatten

close exits the alert symbol only. flatten liquidates every open position on the leader account — including manual trades and other strategies.

{
  "action": "close",
  "symbol": "{{ticker}}",
  "id": "{{ticker}}-exit-{{time}}"
}

{
  "action": "flatten",
  "symbol": "{{ticker}}",
  "id": "flatten-all-{{time}}"
}

Every payload needs symbol, including flatten. Flatten still liquidates the whole account — the field is required by the payload format, not used to pick what to close. Omit it and the alert is rejected with a 400, and TradingView does not retry a 4xx.

Idempotency

TradingView retries webhooks on 5xx. Use a stable id built from bar {{time}}, not wall-clock {{timenow}}, so a retry of the same fill keeps the same id. If you omit id, MimikTrader keys on the bar time when the JSON includes time — so same-bar duplicates collapse — and only fall back to a 10-second fingerprint when it includes neither. Never put {{timenow}} in the time field — it changes on every post, so retries stop matching.

Common rejection reasons

• Plain-text default alert messages instead of JSON
• Wrong webhook URL (the secret is in the URL, not the JSON)
• Strategy group with zero or multiple leaders
• Account locked by daily loss, trailing drawdown, or consistency
