Hi,
I had an idea that "almost" solved the problem: to use some arrays shifted of N
days to "built" the week.
I post here the code to share it and to catch suggestion to solve the problem
that it still exists: having used in not normal way the timeframecompress
function there are problems in weeks with less than 5 trading days like Xmas
period. Of course it's not a problem of AB, it's more a misuse of the function.
The product is a composed graph with 5 colors bar (one every 5 days) and also a
black dashed line that show the problem occuring in period like Xmas
I hope it could help giving an (maybe wrong) idea and not produce confusion in
the use of AB timeframe functions
PS I also had to code a function to calculate MACD on an array because the
built in function uses always C
function MACDmy( array, Sh, Lo )
{
eSh = EMA( array, Sh );
eLo = EMA( array, Lo );
return eSh -eLo;
}
function SignalMy( array, smooth )
{
return EMA( array, smooth );
}
function HistMACD( array, Sh, Lo, Smooth )
{
m = MACDmy( Array, Sh, Lo );
s = SignalMy( m, smooth );
return m - s;
}
Ar0 = TimeFrameCompress(Ref(C,-0), 5*inDaily,compressLast);
HMACD0 = TimeFrameExpand(HistMACD(Ar0,12,26,9), 5*inDaily,expandPoint );
Ar1 = TimeFrameCompress(Ref(C,-1), 5*inDaily,compressLast);
HMACD1 = TimeFrameExpand(HistMACD(Ar1,12,26,9), 5*inDaily ,expandPoint );
Ar2 = TimeFrameCompress(Ref(C,-2),5*inDaily,compressLast);
HMACD2 = TimeFrameExpand(HistMACD(Ar2,12,26,9), 5*inDaily,expandPoint );
Ar3 = TimeFrameCompress(Ref(C,-3),5*inDaily,compressLast);
HMACD3 = TimeFrameExpand(HistMACD(Ar3,12,26,9), 5*inDaily,expandPoint );
Ar4 = TimeFrameCompress(Ref(C,-4),5*inDaily,compressLast);
HMACD4 = TimeFrameExpand(HistMACD(Ar4,12,26,9), 5*inDaily,expandPoint );
Plot( HMACD0, "Weekly MACDmy Histogram", colorPink, styleArea | styleNoLabel,
Null, Null, Null, -1 );
Plot( Ref(HMACD1,1), "Weekly MACDmy Histogram", colorGreen, styleArea |
styleNoLabel, Null, Null, Null, -1 );
Plot( Ref(HMACD2,2), "Weekly MACDmy Histogram", colorOrange, styleArea |
styleNoLabel, Null, Null, Null, -1 );
Plot( Ref(HMACD3,3), "Weekly MACDmy Histogram", colorPaleGreen, styleArea |
styleNoLabel, Null, Null, Null, -1 );
Plot( Ref(HMACD4,4), "Weekly MACDmy Histogram", colorGrey50, styleArea |
styleNoLabel, Null, Null, Null, -1 );
tot = Nz(HMACD0) + Nz(Ref(HMACD1,1)) + Nz(Ref(HMACD2,2)) + Nz(Ref(HMACD3,3)) +
Nz(Ref(HMACD4,4));
Plot( tot , "Weekly MACDmy Histogram", colorBlack, styleDashed | styleNoLabel,
Null, Null, Null, 1 );
