Pine Script Webhook JSON for TradersPost

Fires the exact JSON payload TradersPost expects from a TradingView alert — buy, sell, and exit actions built at runtime with alert().

Copy//@version=6
strategy("TradersPost Webhook JSON", overlay=true, calc_on_every_tick=false)

// ── Inputs ──────────────────────────────────────────────
qty = input.int(1, "Contracts", minval=1)

// ── Entry logic (replace with your own conditions) ───────
longCondition  = ta.crossover(ta.ema(close, 9), ta.ema(close, 21))
shortCondition = ta.crossunder(ta.ema(close, 9), ta.ema(close, 21))

// ── TradersPost JSON payloads (built at runtime) ─────────
// {{...}} dialog placeholders are NOT processed inside alert(),
// so the ticker and quantity are concatenated with str.tostring.
buyMsg  = '{"ticker": "' + syminfo.ticker + '", "action": "buy", "quantity": ' + str.tostring(qty) + '}'
sellMsg = '{"ticker": "' + syminfo.ticker + '", "action": "sell", "quantity": ' + str.tostring(qty) + '}'
exitMsg = '{"ticker": "' + syminfo.ticker + '", "action": "exit"}'

if longCondition
    strategy.entry("Long", strategy.long, qty=qty)
    alert(buyMsg, alert.freq_once_per_bar_close)

if shortCondition
    strategy.entry("Short", strategy.short, qty=qty)
    alert(sellMsg, alert.freq_once_per_bar_close)

// Call from your own exit logic when you flatten:
// alert(exitMsg, alert.freq_once_per_bar_close)

Settings

• qty — contract quantity sent in the payload and used for the entry. Default 1.

How to use

• Paste into the Pine Editor, add to chart, and replace the EMA-crossover placeholder with your own entry conditions.
• Create one alert on the strategy: condition "Order fills and alert() function calls", and paste your TradersPost webhook URL in the Notifications tab.
• Leave the alert dialog message box untouched — the JSON comes from alert() at runtime.
• Test against a TradersPost paper account before pointing it at a funded account.
