Re: [amibroker] Zig-zag based on High and low possible ?, AmiBroker Email List Archive

Hi Berti,

I think this idea is harder than it sounds, since one array may produce more
peaks and troughs than the other so that they will not necessarily follow in
sync or fall on the same bar as you might expect. For example, plot the code
below on CSCO to see that the Zig( Low ) generates more peaks/troughs than
the Zig( High ). I suppose this makes some sense, since prices often decline
more sharply than they advance. I have written the code to try and work
around this - It goes from high peak to next low trough to next high peak,
etc...   See if it is what you are looking for. It also plots the Zig(
High ) and Zig( Low ) for reference (see attached pic).

Steve

Pct = 10;

Peaks = PeakBars( High, Pct ) == 0;

Troughs = TroughBars( Low, Pct ) == 0;

Uptrend = Flip( Troughs, Peaks );

Point = Uptrend != Ref( Uptrend, -1 );

Point[BarCount-1] = 1;

Price1 = IIf( Uptrend, ValueWhen( Point, Low ), ValueWhen( Point, High ) );

Price2 = IIf( Uptrend, ValueWhen( Point, High, 0 ), ValueWhen( Point, Low,
0 ) );

Bar = BarIndex();

Bar1 = ValueWhen( Point, Bar );

Bar2 = ValueWhen( Point, Bar, 0 );

Slope = ( Price2 - Price1 ) / ( Bar2 - Bar1 );

Offset = Price1;

HiLoZig = ( Bar - Bar1 ) * Slope + Offset;

Plot( HiLoZig, "Zig ( Hi To Lo )", colorYellow, styleLine );

Plot( Zig( High, Pct ), "Zig ( Highs )", colorPaleGreen, styleLine );

Plot( Zig( Low, Pct ), "Zig ( Lows )", colorPink, styleLine );

Plot( Close, "Close", colorBlue, styleCandle );
