Default Classic Darvas Box Formulas For Metastock

CLASSIC DARVAS BOX FORMULAS FOR METASTOCK

The first formula is "Darvas High" which identifies new period highs followed by three lower highs.

Name of Indicator: Darvas High

Formula:

Periods:=100; { this is the only place the number of periods is set}

If((Ref(H,-3) >= Ref(HHV(H,Periods),-4))

AND Ref(H,-3) > Ref(H,-2)

AND Ref(H,-3) > Ref(H,-1)

AND Ref(H,-3) > H,

Ref(H,-3), PREVIOUS );

Name of Indicator: New Darvas High

Formula:

dh:= Fml("Darvas High");

def:=IsDefined(dh) AND IsDefined(Ref(dh,-2));

(def AND Ref(def,-1)=0) + (dh AND Ref(dh,-1)<>dh);

Name of Indicator: New Darvas Low

Formula:

dh:= Fml("Darvas High");

ndl:=(Ref(L,-3) < Ref(L,-2) AND Ref(L,-3) < Ref(L,-1)

AND Ref(L,-3) < L AND Ref(H,-2) < dh

AND Ref(H,-1) < dh AND H < dh);

def:=IsDefined(dh) AND IsDefined(Ref(dh,-1));

(def AND Ref(def,-1)=0)+ (ndl AND (Ref(ndl,-1) < 1))



Name of Indicator: Darvas Low

Formula:

If( Fml("New Darvas Low") , Ref(L,-3), PREVIOUS);

Name of Indicator: Darvas Box End

Formula:

end:=BarsSince(Fml("New Darvas High")) <

BarsSince(Ref(Fml("New Darvas Low"),-1));

def:=IsDefined(end) AND IsUndefined(Ref(end,-1));

(def AND Ref(def,-1)=0)+ (end AND Fml("New Darvas Low"))

We are now in a position to plot the High and Low of the Darvas box.

Name of Indicator: Darvas Box High

Formula:

dbe:=Fml("Darvas Box End");

dbhi:=If(dbe AND IsDefined(Ref(dbe,-1)), Fml("Darvas High"), PREVIOUS);

If(dbhi=0,H+0.0000001,dbhi)

Name of Indicator: Darvas Box Low

Formula:

dbe:=Fml("Darvas Box End");

bl:=If(dbe AND IsDefined(Ref(dbe,-1)), Fml("Darvas Low"), PREVIOUS);

If(bl=0,L-0.0000001,bl)

Next we need to develop the Sell Indicator. First we look for possible sell signals.

Name of Indicator: Darvas Poss Sell

Formula:

dsl:=L < Fml("Darvas Box Low");

def:=IsDefined(dsl) AND IsDefined(Ref(dsl,-1));

(def AND Ref(def,-1)=0)+(dsl AND (Ref(dsl,-1)<dsl))

Name of Indicator: Darvas Sell

Formula:

sell:=BarsSince(Fml("Darvas Box End")) <

BarsSince(Fml("Darvas Poss Sell"));

def:=IsDefined(sell) AND IsDefined(Ref(sell,-1));

((def AND Ref(def,-1)=0) + (sell = 0 AND Ref(sell,-1)=1))

Name of Indicator: Darvas Buy

Formula:

dc:= Fml("darvas sell");

{ change the following line to H>Fml("Darvas Box Hi") .. for Classic Darvas}

db:= C>Fml("Darvas Box Hi") AND

(BarsSince(Fml("darvas box end")) < BarsSince(Fml("darvas sell")));

dto:=If(db AND PREVIOUS=0,1,If(dc,0,PREVIOUS));

dto AND (Ref(dto,-1) =0)

Using these formulas it is simple to create a new Metastock Expert Advisor for Darvas. Create a New advisor, call it Darvas and fill in the following tabs

For the Trends tab I used the somewhat arbitrary

Bullish C >= Fml("Darvas Box Low");

Bearish C < Fml("Darvas Box Low");

For Symbols tab use

Buy: up arrow graphic, formula Fml("Darvas Buy")

Sell: down arrow graphic, formula Fml("Darvas Sell")

For Alerts tab use

Buy: formula Fml("Darvas Buy") and some suitable text message such as "buy on next open"

Sell: formula Fml("Darvas Sell") and some suitable text message such as "sell on next open"

The super moderator should have posted a screen shot alongwith this metastock code, because nothing is basically clear from it, except that you create 7/8 indicators and create an expert.The super moderator should have tried to find out if it works or not. As far as I know it will not give the desired result. Ask Guppy.

Probably he was just trying to help people get started. and as you know, very little in life is an exact precise science, rather we start into something and then have to learn and refine a lot......

Perhaps you would be able to post what you know to be the correct parameters and thereby save people some work.......

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( box1, "" , 1 + statearray, styleThick);
Plot( box2, "" , 1 + statearray , styleThick);
_SECTION_END();


The above code will plot the 2 sides (High /Low) of the Box on the chart. The idea is to trade the breakout on either side.


Regards
Sanjay

I have tried out all the indicators before posting them here. They all work.

Sethi Darvas is a proprietory darvas formula. Here the boxes are clear cut. Sanjay's Afl for amibroker is also good. If anyone has plotted the Darvas in Metastock using the code given in this forum earlier, pl submit.
The png file is sethi darvas and jpg file is from amibroker.

hi jalanp
Thanks for the clarification .I am still unable to get the box.Not that it matters because I think what matters is the horizontal lines and not the vertical ones.
