### Technical Indicator Usage Example

Source: https://github.com/anandanand84/technicalindicators/blob/master/testdocs.html

An example of how to use a technical indicator function (e.g., SMA) within the Monaco Editor. This snippet demonstrates calling an indicator with specific parameters and logging the result to the console.

```typescript
//Try indicators and check console
let result = sma({period : 10 , values: [1,2,3,4,5,6,7,8,9]});
console.log(result)
```

--------------------------------

### Install Specific TypeScript Version

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Installs TypeScript version 2.0.0 globally using npm. This specific version is recommended to prevent 'max call stack reached' errors.

```bash
npm install -g typescript@2.0.0
```

--------------------------------

### Indicator Instance Methods (nextValue, getResult)

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Explains how to use indicator instances for incremental calculations. Initialize with data, get all results using `getResult()`, and then process new data points with `nextValue()`.

```javascript
var sma = new SMA({period : period, values : []});
var results = [];
prices.forEach(price => {
  var result = sma.nextValue(price);
  if(result)
    results.push(result)
});
```

```javascript
var sma = new SMA({period : period, values : prices});
sma.getResult(); // [5.5, 6.6, 7.7, 8.9]
sma.nextValue(16); // 10.1

// Note: Calling nextValue will not update getResult() value.
```

--------------------------------

### Include TechnicalIndicators for ES5 Browsers

### Use SMA Indicator in Browser (Global)

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Demonstrates how to use the SMA indicator directly from the global scope in a browser environment after including the library.

```javascript
sma({period : 5, values : [1,2,3,4,5,6,7,8,9], reversedInput : true});
```

--------------------------------

### Use SMA Indicator in Browser (Class Method)

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Demonstrates how to use the SMA indicator by calling its static calculate method, available after importing or including the library.

```javascript
SMA.calculate({period : 5, values : [1,2,3,4,5,6,7,8,9]});
```

--------------------------------

### Calculate Bullish/Bearish Indicator

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Demonstrates how to use the library's bullish function to determine if a bullish pattern is present based on input price data. Requires the 'technicalindicators' module.

```javascript
var twoDayBullishInput = {
  open: [23.25,15.36],
  high: [25.10,30.87],
  close: [21.44,27.89],
  low: [20.82,14.93],
}

var bullish = require('technicalindicators').bullish;

bullish(twoDayBullishInput) //true
```

--------------------------------

### Configure Webpack for TechnicalIndicators

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Configures Webpack to correctly resolve the main fields for the technicalindicators library, ensuring compatibility with module and main entry points.

module.exports = {
  resolve: {
    mainFields: ["module", "main"]
  }
}
```

--------------------------------

### Calculate Indicator Statically

Source: https://github.com/anandanand84/technicalindicators/blob/master/README.md

Shows how to use the static `calculate` method available on each indicator. This method allows calculation without instantiating an object, using either the specific indicator module or the main library.

```javascript
const sma = require('technicalindicators').sma;
var prices = [1,2,3,4,5,6,7,8,9,10,12,13,15];
var period = 10;
sma({period : period, values : prices})
```

```javascript
const SMA = require('technicalindicators').SMA;
var prices = [1,2,3,4,5,6,7,8,9,10,12,13,15];
var period = 10;
SMA.calculate({period : period, values : prices})
```

--------------------------------

### Code Execution Function

Source: https://github.com/anandanand84/technicalindicators/blob/master/index.html

A utility function to execute the code written in the Monaco editor. It uses `eval` to parse and run the editor's content as an asynchronous function.

```javascript
var executeCode = function() {
    var fn = eval('(async function test() {'+editor.getValue()+'})');
    console.log(fn());
}
```

--------------------------------

### Import SMA Indicator in Node.js
