Visual Studio  
c# .NET 6.0  
Alpaca SDK 6.05

Wanted to try out this API and check out this example: [A Simple Mean Reversion Stock Trading Script in C#](https://alpaca.markets/learn/mean-reversion-stock-trading-csharp/)

wanted to see if I could adapt the code to what I need but wont run due to error and cant find a way around it

class MeanReversionPaperOnly  
{  
private string API\_KEY = “REPLACEME”;  
private string API\_SECRET = “REPLACEME”;  
private string API\_URL = “[https://paper-api.alpaca.markets](https://paper-api.alpaca.markets)”;

```
    private string symbol = "SPY";
    private Decimal scale = 200;

   private ***RestClient*** restClient;

    private Guid lastTradeId = Guid.NewGuid();
    private List<Decimal> closingPrices = new List<Decimal>();

    public void Run()
    {
       restClient = new ***RestClient*** (API_KEY, API_SECRET, API_URL);

        // First, cancel any existing orders so they don't impact our buying power.
        var orders = restClient.ListOrdersAsync().Result;
        foreach (var order in orders)
        {
            restClient.DeleteOrderAsync(order.OrderId);
        }

```
