MT5 Webhook Alert Template JSON alerts for any bridge A ready-to-use alert template that fires webhook-compatible JSON messages on
EMA-cross + RSI-filtered signals. Built to send PulseWire alerts straight to
MetaTrader 5 through any webhook bridge.
HOW TO USE (2 minutes):
1. Add the indicator to your chart.
2. Create an alert (Alt+A) on this indicator, condition "Any alert() function
call", and paste your bridge's webhook URL into the Webhook URL field.
3. Done — the alert message is already valid JSON, don't edit it.
MESSAGE FORMAT (works with most MT5 bridges):
{"action":"buy","symbol":"EURUSD","lot":0.01,"sl":50,"tp":100}
{"action":"sell","symbol":"EURUSD","lot":0.01,"sl":50,"tp":100}
- action: buy | sell | close | closeall
- sl / tp: distance in points (optional, set to 0 to omit)
- Symbol override input if your broker uses suffixes (e.g. EURUSD.pro)
Alerts evaluate on bar close (no intrabar repainting). The indicator is also
useful on its own as a visual signal — no bridge required.
DEFAULT SETTINGS WARNING:
The shipped defaults (Fast EMA 1 / Slow EMA 3 / RSI 2) are an intentionally
fast demo configuration so you can see signals right away. They will fire
VERY often, including many low-quality crosses. Signals only confirm on bar
close, so a cross can still appear and disappear intrabar before confirming.
Tune Fast/Slow EMA and RSI length to your own strategy and symbol before
using it live — treat the defaults as a starting point, not a ready system. Indicator
TO_JSONTO_JSON
A lightweight Pine Script v6 library for converting PulseWire series data into JSON-formatted alert payloads.
`TO_JSON` is designed for users who want to export chart data to external systems through PulseWire alerts.
It helps transform rolling series such as OHLCV, indicator values, or text states into JSON-compatible arrays and wraps them into a structured message for webhooks, bots, dashboards, or automated workflows.
What this library does
This library provides helper functions to:
- convert float series into JSON arrays
- convert integer series into JSON arrays using a sentinel value as `null`
- convert string series into JSON arrays with fallback filling and JSON-safe escaping
- wrap custom payloads into a top-level JSON alert message with symbol, timeframe, timestamp, and token
It is especially useful when you want to send the latest `N` bars of market data or indicator values to an external service.
Features
- Rolling array export for `float`, `int`, and `string` series
- Chronological output from oldest to newest
- `null` support for missing values
- JSON-safe string escaping
- Simple wrapper for alert message generation
- Works well for webhook-based automation and downstream parsing
Exported functions
### `series_to_array_float_null(series float src, int N)`
Converts the latest `N` values of a float series into a JSON array string.
Missing values are exported as `null`.
`series_to_array_int_sentinel(series int src, int N, int sentinel)`
Converts the latest `N` values of an integer series into a JSON array string.
The specified sentinel value is exported as `null`.
`series_to_array_str_fill(series string src, int N, string fill="")`
Converts the latest `N` values of a string series into a JSON array string.
Missing values are replaced with `fill`, and strings are escaped for JSON compatibility.
`json(simple string token="1234567890", string info="", simple string symbol="AUTO")`
Wraps a custom JSON payload into a top-level alert message including:
- symbol
- timeframe
- current timestamp
- human-readable time
- info payload
- token
Typical use case
A common use case is exporting the last bars of:
- time
- open
- high
- low
- close
- volume
- moving averages
- custom signals
into one flat JSON object, then embedding it into the alert message.

Object: object oriented programming made possible! Hash map's in Pinescript?? Absolutely
This Library is the first step towards bringing a much needed data structure to the Pine Script community.
"Object" allows Pine coders to finally create objects full or unique key:value pairs, which are converted to strings and stored in an array. Data can be stored and accessed using dedicated get and set methods.
The workflow is simple, but has a few nuances:
0. Import this library into your project; you can give it whatever alias you'd like (I'll be using obj)
1. Create your first object using the obj.new() method and assign it a variable or "ID".
2. Use the object's ID as the first argument into the obj.set() method, for the key and value there's one extra step required. They must be added as arguments to the appropriate prop_() method.
Note: While objects in this library technically only store data as strings, any primitive data type can be converted to a string before being stored, meaning that one object can hold data from multiple types at once. There's a trade off though..Pine Script requires that all exported function parameters have pre-defined types, meaning that as convenient as it would be to have a single method for storing and returning data of every type, it's not currently possible. Instead there are functions to add properties for each individual type, which are then converted to strings automatically (the original type is flagged and stored along with the data). Furthermore, since switch/if statements can only return values of the same type, there must also be "get" methods which correspond with each type. Again, a single "get" method which auto-detects the returned value's type was the goal but it's just not currently possible. Instead each get method is only allowed to return a value of its own type. No worries though, all the "get" methods will throw errors if they can't access the data you're trying to access. In that error message, you'll be informed exactly which "get" method you need to use if you ever lose track of what type of data you should be returning.
3. The second argument for obj.set() method is the obj.prop_() method. You just plug in your key as a string and your value and you're done. Easy as that.
Please do not skip this step, properties must be formatted correctly for data to be stored and accessed correctly
4. Obj.get_ (s: string, f: float, b: bool, i: int) methods are even easier, just choose whichever method will return the data type you need, then plug in your ID, and key and that's it. Objects will output data of the same type they were stored as!
There's a short example at the end of the script if you'd like to see more!
prop_string(string: key, string: value)
returns property formatted to string and flagged as string type
prop_float(string: key, float: value)
returns property formatted to string and flagged as float type
prop_bool(string: key, bool: value)
returns property formatted to string and flagged as bool type
prop_int(string: key, int: value)
returns property formatted to string and flagged as int type
