Inputs: ThresholdValue(0);
Variables: EntryPrice(0), ExitPrice(0), Difference(0), Result(0);

condition1 = close > Average(close, 21);

If condition1 and EntryPrice=0 Then
    EntryPrice = Close
else If condition2 Then Begin
    ExitPrice = Close;
    if EntryPrice <> 0 then
        Difference = ExitPrice - EntryPrice;

End;

If Difference >= ThresholdValue Then
