What is a stock trading signals JSON format?

It is a stable set of JSON keys used to describe a trading alert, such as symbol, action, price, timeframe, and signal ID. The receiving webhook must define what each key means before the payload is used downstream.

Should JSON prices be strings or numbers?

Send prices as JSON numbers when the receiver expects numeric values. Text fields such as symbol and action need double quotes. Validate a rendered alert because a placeholder or dynamic value can still produce invalid JSON.

Can alertcondition() create dynamic JSON?

alertcondition() accepts a constant message and can insert supported TradingView placeholders. Use alert() when the script needs to assemble a dynamic series string from calculated values.

Does a TradingView JSON alert place a trade?

No. The alert only sends a message. A separate, authenticated receiver must validate the payload and decide what to do with it. Pineify generates editable Pine Script but does not sit in the order execution path.

Stock Trading Signals JSON Format for TradingView Alerts

A stock trading signals JSON format should be predictable for the system that receives it. Start with a small schema, keep text in double quotes, send numbers as numbers, and validate the exact payload before connecting it to any automated workflow.

Generate the Pine Script

A practical JSON schema

This example carries the minimum context most receivers need. Add keys only when the endpoint has a documented use for them. A JSON alert is a message contract, not an order by itself.

symbol identifies the chart instrument
action uses a controlled value such as buy or sell
price stays numeric for downstream validation
signal_id makes logs and deduplication easier

{
  "symbol": "{{ticker}}",
  "action": "buy",
  "price": {{close}},
  "timeframe": "{{interval}}",
  "signal_id": "ema_cross_up"
}

Pine Script v6 dynamic alert example

The alert() function accepts a dynamic series string. This sample waits for a confirmed bar, converts the price to text for string assembly, and leaves the resulting JSON price unquoted so the receiver gets a number.

//@version=6
indicator("EMA signal JSON", overlay = true)

fastEma = ta.ema(close, 9)
slowEma = ta.ema(close, 21)
longSignal = ta.crossover(fastEma, slowEma)

plot(fastEma, color = color.blue)
plot(slowEma, color = color.orange)

if longSignal and barstate.isconfirmed
    payload = '{"symbol":"' + syminfo.ticker +
      '","action":"buy","price":' +
      str.tostring(close, format.mintick) +
      ',"timeframe":"' + timeframe.period +
      '","signal_id":"ema_cross_up"}'
    alert(payload, alert.freq_once_per_bar_close)

Validation and webhook safety

Validate the rendered message

Do not validate only the template. Trigger a test alert and inspect the message received after placeholders or dynamic values are resolved.

Keep credentials out of JSON

TradingView warns against putting passwords or login credentials in the webhook body. Authenticate and authorize at the receiver.

Make events idempotent

Use a signal identifier and receiver-side deduplication so a retry does not create an unintended duplicate action.

Separate signal from execution

Treat Pine Script as the signal source. The receiver remains responsible for schema checks, limits, logging, and any execution decision.
