Thanks Anthony
This would be what you have referenced
***********
weeklyprice=C;
Weekly=ValueWhen(DayOfWeek() > Ref( DayOfWeek(),1),WeeklyPrice);
W6ema = EMA(weekly,30);// 6 weeks * 5 days per week
W13ema = EMA(weekly,65);// 13 weeks * 5 days per week
MACDSignal = EMA((W6ema - W13ema),25);// 5 weeks * 5 days per wee
***********
>From this I have a few questions to help me understand what I am seeing,
if someone can please help a programming newbie.
1. The values of a normal MACD are 26, 12 , 9. This formula appears to
be for half of that at 13, 6, 5. Is there a reason for this, or could I
use the normal periods in weeks converted into days (ie 13*5=65 etc)
2. I cannot understand the valuewhen statement in regard to the
dayfweek()>ref(dayofweek(),1)
Am I wrong in assuming that you want today's dayvalue to be greater than
tomorrows dayvalue. Does that mean that the value would be for Saturday
as its value is 6 and sunday is 0. Without seeming too stupid this gives
the day as Saturday when there is no trading, but it needs to find the
closing price for Saturday. I did put this in to an AFL search and it
seems to work, but I do not understand how or why it works.
3. Also in the valuewhen statement the AB help screen has an additional
part at the end of a number being the x number of previous occurence. eg
'1' is the most recent occurence. Does AB have default value of 1 if it
is omitted?
Thanks in advance
Graham
