Hi friend rv
The condition you are aiming is probably,
macd histogram > 0;
macdhistogram > ref(macdhistogram,-1);
rise or fall in histogram in 5 bars > x% of histogram;
The below formula may help
--------------------------------------------------
//Use on weekly charts to determine Trend Changes.
// if the Weekly Bars are Green check the daily bars for LONG entries, if the
Weekly Bars on Red check the daily for Short entires.
//Formula:

SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g,
Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
TimeFrameSet( inDaily) ;//ignore this codeline if you deal with intraday
//MACD
r1 = Param( "Impulse Fast avg", 12, 2, 200, 1 );
r2 = Param( "Impulse Slow avg", 26, 2, 200, 1 );
r3 = Param( "Impulse Signal avg", 9, 2, 200, 1 );
ml = MACD(r1, r2);
sl = Signal(r1,r2,r3);
Hist = ml-sl;
MACUP = Hist > Ref(Hist,-1);
MACDN = Hist < Ref(Hist,-1);
BarColor = IIf(MACUP,colorGreen,IIf(MACDN,colorRed,colorBlue));
Plot( C, "Close", BarColor, styleNoTitle | ParamStyle("Style") |
GetPriceStyle() );
===================================================
please note
you need to add hist plot code line
and modify lines here below for action on histogram
MACUP = Hist > Ref(Hist,-1);//gives rising histogram
MACDN = Hist < Ref(Hist,-1);//gives falling histogram
then the complex condition
hist rise in 5 bars to be more than x%,where x =1 or 2 etc
The rise of x units must happen in 5 bars,
starting from?? which point not clear(from wherever the rise of fall begins)
This part only an expert can do.
if rise of hist happens as planned,trade validated signal comes
otherwise no signal or trade validation failed may come.
here
hist > 0 or hist < 0
is to be added in MACUP and MACDN codelines
then
plot the histogram ,plot the macd line,plot signal line
exclude price
BarColor = IIf(MACUP,colorGreen,IIf(MACDN,colorRed,colorBlue));
change this to hist color
------------------------
Any way the final afl is possible only if an expert ike mike or reinsley etc
spare their coding skills.
In the absence of other info, try with above info as a base guideline,though
may not be correct,as I am a novice.
cheers
