While having as many values as possible returns more "accurate" MACD values, the minimum number of values needed to return a set of values is the slow length + signal length - 1.  

For example, using the traditional MACD lengths of 12, 26, and 9, one would need a minimum of 34 values (26 + 9 - 1) to return MACD values.
