    Posted: 07 Oct 2010 at 3:51pm
Hi guys,

I have no programming knowledge other than cutting and pasting into the indicator builder. I have been using Bill William’s Profitunity System with my forex brokers platform and would like to add it to my BullChart. I need to add Fractals to my screen.

Fractals - 5 bars sequence where middle one has highest High / lowest Low and its preceded and followed two bars have lower highs / higher lows preceded by two lower highs and is followed by two lower highs:

{ Defining up fractal ) =

High1 := Ref(HIGH,-2);

High2 := Ref(HIGH,-1);

High3 := Ref(HIGH,0);

High4 := Ref(HIGH,1);

High5 := Ref(HIGH,2);

If((High3 > High1) AND (High3 > High2) AND (High3 > High4) AND (High3 >

High5), High3,0);

 

{Defining Low Fractal } =

Low1 := Ref(LOW,-2);

Low2 := Ref(LOW,-1);

Low3 := Ref(LOW,0);

Low4 := Ref(LOW,1);

Low5 := Ref(LOW,2);

(If((Low3 low5), Low3,0))


Anyone know how to do this? Help would be much appreciated!

Heya Tenaka,

I have seen them on MetaTrader, but not on Bullcharts so here goes nothin lol.
If you can paste a link to the Bill williams method of how it works then that would
allow others to see the use of this thing :)
 
 
 

[Description="Fractal of 5 bars, Max"]

[target=price]

{ Fractal Highs }

[linestyle=points; color=blue; width=5]

If(H>ref(H,1) and H>ref(H,-1) and ref(H,-1)>ref(H,-2) and ref(H,1)>ref(H,2), H*1.008,undefined);

{ Fractal Lows }

[color=indian red]

If(L<ref(L,1) and L<ref(L,-1) and ref(L,-1)<ref(L,-2) and ref(L,1)<ref(L,2), L*0.992,undefined);

Thanks Maximo!
 
That formula works well. Only problem is that I don't know how to have them connected to the candle sticks, it would be very convenient to have the up fractals sit just above the candles and the down fractal sit just below.
 
Once again thank you!

You can move the location of the indicator dot by adjusting those numbers that multiply the H*1.008 (High) and the L*0.992 (Low).   If that's what you mean?
  Currently thats just a fraction under 1% above and below the candles/bars.
3 bar fractals are often used as well.  I'll paste that when time permits.

Also a good visual aid for determining trend direction. ie.
Higher Higher, Higher Low, Lower Low, Lower High. 
 
 
 
[Description="Fractal of 3 bars, Max"]

[target=price]

{ Fractal High }

[linestyle=points; color=blue; width=5]

If(H>ref(H,1) and H>ref(H,-1), H*1.005,undefined);

{ Fractal Low }

[color=indian red]

If(L<ref(L,1) and L<ref(L,-1), L*0.995,undefined);

Hi guys,

First of all thanks again for the help maximo.

I am wanting to test fractals in tradesim, so I need the above formular to remember the most recent UP fractal high and the most recent DOWN fractal low and draw it on the chart similar to the support/resistance indicator draws a line. This way I could set a buy signal for when the price breaks above the previous up fractal's high. Can this be done?

For those who aren't sure how to use fractals I have a link to Bill William's use of fractals. They can be used on shares eventhough the link is from a forex broker.

http://www.alpari.co.uk/en/market-analysis-guide/chaos-theory/index.html

I use them with the Awesome Oscillator (AO):

ma(ma(MP(),5,S) - ma(MP(),34,S),5,S)

you will need to adjust the plot to the up and down wave style thingy.

I have had good success with the method, and am sure it can be better tuned by backtesting different posistion sizing, risk/reward, stops etc...

I'd be very appreciative if my above post could be turned into a formula.

Cheers,

Tanaka Smile

Hi Tanaka,
 
They are very good for showing support and resistance.
 
Here is the complete indicator and signal for testing :)
 
 
Note: HoldLevelPeriod can be set to 1 to just show the fractal bars.
  I have also added a close price option which, shows a difference in the
 levels found and provides another testing option.
 
 
 

[Description="Fractal of 5 bars indicator and signal, Max"]

[target=price]

HoldLevelPeriod := Input("Hold Level Period",15,1);

UseHigh:= Input("Use High: 1=True, 0=Close",1,0);

{ Fractal Highs }

[linestyle=points; color=blue; width=5]

UpFractal:=If(UseHigh and H>ref(H,1) and H>ref(H,-1) and ref(H,-1)>ref(H,-2) and ref(H,1)>ref(H,2), H*1.005,If(UseHigh = 0 and H>ref(C,1) and H>ref(C,-1) and ref(C,-1)>ref(C,-2) and ref(C,1)>ref(C,2), H*1.005,undefined));

FrU:=ValueWhen(1,UpFractal,UpFractal);

FrUb:=If(H < FrU and barssince(UpFractal)<HoldLevelPeriod,FrU,undefined);

FrUb;

{ Fractal Lows }

[color=indian red]

DownFractal:=If(UseHigh and L<ref(L,1) and L<ref(L,-1) and ref(L,-1)<ref(L,-2) and ref(L,1)<ref(L,2), L*0.995,If(UseHigh = 0 and L<ref(C,1) and L<ref(C,-1) and ref(C,-1)<ref(L,-2) and ref(C,1)<ref(C,2), L*0.995,undefined));

FrD:=ValueWhen(1,DownFractal,DownFractal);

FrDb:=If(L > FrD and barssince(DownFractal)<HoldLevelPeriod,FrD,undefined);

FrDb;

{ Markers }

[name=Above; linestyle=marker; marker=type2]

SignalUp:=If(Hist(FrUb,1) and H > FrU,FrU,undefined);

SignalUp;

[name=Below; linestyle=marker; marker=type1]

SignalDown:=If(Hist(FrDb,1) and L < FrD,FrD,undefined);

SignalDown;

Thank you so much Maximo,

I have just loaded the formula and it looks fantastic! I'm going to have a play around with it tomorrow, and I will let everyone know how it goes.

The look back feature should be very handy while back testing.

You are correct, they are good at showing support and resistance.

p.s I'd be very interested to know if others on this forum are using fractals

Nice to hear Tanaka,
 
This should be good to use with a longer term average and volume period.
 
Similar to 10-30 day breakout and Darvas breaks of resistance too.
