why are there computational differences in the following code?

[William Roeder]

SergioTForex: why are there computational differences in the following code?

In the preceding code, you compute a five (5) period simple (SMA) and compare that to a five (5) period exponential (EMA). Why would you think they would ever be the same?

sorry, I only realized the mistake now
