# Alpha Radar

> High-probability market signals with positive expected value net of trading fees

# Alpha Radar (+EV Signals)

CrypTech's Alpha Radar scans multi-venue order flow, perpetual funding divergence, and DEX liquidity migration to surface high-conviction trade setups with **positive expected value (+EV)** net of exchange fees and gas.

***

### Query Parameters

**category** `string`

Filter radar candidates by category.

Options: `all` (default), `defi`, `l1`, `meme`, `ai`, `rwa`.

**min\_ev** `number` (default: 1.5)

Minimum expected value percentage net of trading fees (e.g. `2.0` for +2.0% EV).

**limit** `integer` (default: 10)

Maximum number of opportunities to return (between `1` and `50`).

***

### Response Fields

**status** `string`

Status of the query (`ok`).

**timestamp** `string`

ISO 8601 timestamp of radar calculation.

**count** `integer`

Number of actionable setups returned.

**items** `array of objects`

Active alpha opportunities:

**Item Schema**

**symbol** `string`

Asset ticker (e.g., `ETH`, `SOL`, `LINK`).

**direction** `string`

Trade direction: `LONG` or `SHORT`.

**expected\_value\_net** `number`

Calculated expected value percentage net of taker fees and slippage (e.g. `+3.42%`).

**win\_rate\_probability** `number`

Historical statistical win rate for this quantitative pattern (e.g. `0.68`).

**target\_entry** `number`

Suggested execution price level in USD.

**target\_tp** `number`

Suggested take-profit target in USD.

**target\_sl** `number`

Suggested stop-loss invalidation level in USD.

**time\_horizon** `string`

Expected trade resolution window (e.g., `4h - 12h`).

## Real-Time SSE Stream

For automated execution bots, CrypTech provides a low-latency Server-Sent Events (SSE) push stream:

```http theme={null}
GET https://api.cryptechtoday.com/api/markets/intel/radar/stream
```

Whenever a new high-conviction signal meets your criteria, the server instantly pushes an event without requiring polling:

```javascript JavaScript / Node.js theme={null}
const eventSource = new EventSource(
  'https://api.cryptechtoday.com/api/markets/intel/radar/stream',
  { headers: { 'X-API-Key': process.env.CRYPTECH_API_KEY } }
);

eventSource.onmessage = (event) => {
  const signal = JSON.parse(event.data);
  console.log(`⚡ New Signal: ${signal.symbol} ${signal.direction} (EV: +${signal.expected_value_net}%)`);
};
```
