No wonder, IMHO. A calculation of MACD bases upon EMA that, in turn, being a
recursive formula has a lookback period as a parameter, although in canned
formulas you are not bothered with this issue, since the choice is made for you
by programmers (different in each case). Actually, to achieve an absolute
accuracy you have to have an infinite lookback period. If not, you should
compromise between accuracy and speed of calculations. Since there is no an
industry standard for EMA calculations, it's not surprising to see a difference.
Cannot say for sure why different Display Charts and Scan Database' calculations
are, but aren't they different modules?
Cheers, Vitaly
