When you use an indicator extension, a new indicator is created, So every time you call sma.Minus(price), you will get a new indicator waiting for the first update. The proper way to do it would be:

//Set up the SMA class
private SimpleMovingAverage _sma;
private Identity _price;
private CompositeIndicator<IndicatorDataPoint> _diff;

// In Initialize
_sma = SMA("EURUSD", 10, Resolution.Hour);
_price = Identity("EURUSD");
_diff = _sma.Minus(_price);

// In OnData or elsewhere
Log("Value of sma is" + sma + " and price is" + price + "Difference is---" + _diff);
