Using Promise Wrapper:

``` js

var tulind = require('tulind');
var { promisify } = require('util');


//Promisify the simple moving average
//You can promisify any indicator and use it like this
const sma_async = promisify(tulind.indicators.sma.indicator);

var sma_inc = async (close) => {
var results = await sma_async([close], [3]);
return results ;
};

```
