Changing from Multiple if Statements to Switch and Case with when statements gives Syntax Errors

Hi Guys,

I am having issues with changing from the following:

 #region Trailing Stop Loss

                    continue;
                var positionSize = Math.Round(position.Quantity * (LotClose / 100), 2);
                double lotStep = Symbol.VolumeInUnitsToQuantity(Symbol.VolumeInUnitsStep);
                double steps = positionSize / lotStep;
                if (Math.Floor(steps) < steps)
                {

                #region 1st ATR Break Even
