# Placeholders

Placeholders are special dynamic variables that get replaced with real market data when a webhook is executed. They allow you to build fully dynamic JSON payloads based on price, levels, distances, moving averages, and other metrics.

`{{ticker}}` is replaced with the asset symbol (e.g., BTCUSDT).

`{{close}}` is replaced with the latest closing price at the moment the alert is triggered.

### Cryptovizor now supports a full set of Key Levels placeholders.

Below is the complete matrix of available placeholders.

Here tf may be any timeframe: `5m, 15m, 30m, 1h, 2h, 4h, 12h, 1d.`

### Category: Moving Averages

`{{tf_ma50}}` — simple moving average 50

`{{tf_ma200}}` — simple moving average 200

Exmaples: `{{1h_ma50}}` or `{{12h_ma200}}`

### Category: Support Key Levels

`{{tf_support_center_price}}` — support zone center

`{{tf_support_zone_low}}` — support zone low

`{{tf_support_zone_high}}` — support zone high

`{{tf_support_strength}}` — support strength (merge count)

`{{tf_support_touches}}` — number of touches

`{{tf_distance_to_support_pct}}` — distance to support in percent

`{{tf_support_age_days}}` — support age in days

### Category: Resistance Key Levels

`{{tf_resistance_center_price}}` — resistance zone center

`{{tf_resistance_zone_low}}` — resistance zone low

`{{tf_resistance_zone_high}}` — resistance zone high

`{{tf_resistance_strength}}` — resistance strength (merge count)

`{{tf_resistance_touches}}` — number of touches

`{{tf_distance_to_resistance_pct}}` — distance to resistance in percent

`{{tf_resistance_age_days}}` — resistance age in days

### Arithmetic operations in placeholders

Placeholders support simple arithmetic directly inside webhook JSON.

This allows you to dynamically calculate entries, stop-loss levels, take-profit targets, quantities, and more.

Format:

`{{placeholder operator value}}`

**Allowed operators:**

* `+` addition
* `-` subtraction
* `*` multiplication
*  `/` division

#### Basic examples

Addition:

`{{close + 100}}`

(add 100 to the last close price)

Subtraction:

`{{close - 50}}`

(subtract 50 from the price)

Multiplication — used for percentage changes:

`{{close * 0.97}}`

(price minus 3%)

Division:

`{{1000 / close}}`

(calculate position size for 1000 USD)

#### Percent logic:

price \* 1.05 = +5%

price \* 0.95 = –5%

price \* 0.995 = –0.5%

#### Valid examples:

{{close \* 1.02}} → +2%

{{close \* 0.98}} → –2%

{{1h\_resistance\_zone\_high - 150}} → resistance high minus 150

{{4h\_support\_center\_price + 200}} → support center plus 200

#### Invalid examples (not supported):

{{close + 100 \* 2}}

(two operations — not supported)

{{(close + 100) \* 2}}

(parentheses are not supported)

{{{{close}} + 10}}

(nested placeholders are not supported)

#### Limitations

Parentheses are not supported

Nested placeholders are not supported

Only one operation is allowed:

{{placeholder operator value}}

Operator value cannot contain other placeholders

### **Example JSON (using real placeholders):**

`{`

`“name”: “Cryptovizor Key Levels”,`

`“secret”: “ljj8213138op”,`

`“symbol”: “{{ticker}}”,`

`“side”: “buy”,`

`“open”: {`

`“amount”: “10”,`

`“amountType”: “balanceLeverage”,`

`“scaled”: {`

`“qty”: “5”,`

`“price1”: {`

`“mode”: “ofs”,`

`“value”: “0.5”`

`},`

`“price2”: {`

`“mode”: “value”,`

`“value”: “{{1h_support_center_price * 0.995}}”`    // -0.5% from center of zone

`},`

`“factor”: “1.03”`

`}`

`},`

`“sl”: {`

`“price”: “{{1h_support_zone_low * 0.98}}”`            // -2% from lower boundary of the `support zone.`

`}`

`}`

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cvizor.com/en/modules/signals/webhook/placeholders.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
