Re: [amibroker] Darvas Box

[Jason Hart <jayhart_1972@xxxxxxxxx>]

which code are you using?  I have two one has a red and green line which does not plot the actual boxes and is more of a LT indicator of support/resistence.  The second one I have does plot the boxes. 

 

try this....

 

//////////begin/////////

box1=0;

box2=0;

SetBarsRequired(10000,10000);

procedure fillDarvas(start,end,swap,top, bottom )

{

for ( j = start; j < end; j++)

{

if( box1[j] == swap)

box1[j]= top ;

else

box1[j]= bottom;

if(box2[j] == swap)

box2[j]= bottom ;

else

box2[j]= top;

}

}

BoxArr1 = 0;

BoxArr2 = 0;

StateArray = 0;

DBuy = 0;

DSell = 0;

TopArray = 0;

BotArray = 0;

tick=0;

BoxTop = High[0];

BoxBot = Low[0];

swap=0;

state = 0;

BoxStart = 0;

for (i=0; i<BarCount; i++)

{

if (state==5)

{

TopArray[i]=BoxTop;

BotArray[i]=BoxBot;

if (Low[i]<(BoxBot*(1-tick/100)) || High[i]>(BoxTop*(1+tick/100)))

{

fillDarvas(BoxStart,i,swap,BoxTop,BoxBot);

state = 1;

swap = !swap;

BoxTop = High[i];

BoxStart = i;

}

}

else

{

if (High[i]<BoxTop)

{

if ((state<3) || (Low[i]>BoxBot))

{

state++;

}

else

{

state=3;

}

if (state==3)

BoxBot=Low[i];

}

else

{

state=1;

BoxTop=High[i];

}

}

StateArray[i] = state;

}

fillDarvas(BoxStart,BarCount,swap,BoxTop,BoxBot);

Plot(C,"",3,64);

Plot( box1, "" , 1 + statearray, styleLine );

Plot( box2, "" , 1 + statearray , styleLine );

_SECTION_BEGIN("MA");

P = ParamField("Price field",-1);

Periods = Param("Periods", 15, 2, 200, 1, 10 );

Plot( MA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );

_SECTION_END();

a=(C-Ref(C,-1))/(Ref(C,-1))*100;

Title = Name() + " - " + WriteVal( DateTime(), formatDateTime ) + " - " + " Open: " + O + ", Hi: " + H + ", Low: " + L + ", Close: " + C + " " + NumToStr(a,1.2) + "%" + ", Volume: " +

WriteVal(V,1)+ " ";
