You can close the position once the price crosses below the ema20. Below is an example that creates one position on robot start and if the ema20 crosses above the close the position is closed.

private ExponentialMovingAverage ema20;
private Position position;

// Source is the price (O-L-H-C) used in the ExponentialMovingAverage calculation
[Parameter]
public DataSeries Source { get; set; }

// Period of the ExponentialMovingAverage
[Parameter(DefaultValue = 20, MinValue = 1)]
public int Period { get; set; }

protected override void OnStart()
{
    // Initialize ExponentialMovingAverage Indicator
    ema20 = Indicators.ExponentialMovingAverage(Source, Period);
    Trade.CreateMarketOrder(TradeType.Buy, Symbol, 100000);
}

protected override void OnTick()
{

    // EMA is above price
    if (ema20.Result.HasCrossedAbove(MarketSeries.Close, 0))
    {
        Trade.Close(position);
    }
}


protected override void OnPositionOpened(Position openedPosition)
{
    position = openedPosition;
}
