# `obv` — OBV

> Category: **Volume** · Standard

::: tip Reading the response
Use `POST /api/indicators?explain=true` to include interpretation notes at `indicators[responseKey].explain`. Read numeric results from `columns` and `data` in the same object.
:::

This is a volume indicator.

## Parameters

_No configurable parameters._

## Output columns

| Column |
|------|
| `obv` |



## Native features

This indicator has no independent native feature signals.

Cumulative signed volume depends on the input origin; no pivot-divergence detector exists, so zero-cross or divergence signals would be unfounded.

With `signals: true`, this indicator returns `signals: null`. Numeric values and charts remain available; no crossing, divergence or trade rules are added.

## Example call

```bash
curl -X POST -H "Authorization: Bearer mq_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "exchange": "binance",
    "market":   "perp",
    "symbol":   "BTCUSDT",
    "interval": "5m",
    "limit":    100,
    "calc":     [{"name": "obv"}]
  }' \
