Composite momentum

[kantkant2]

Hi all!
I am really interested in an indicator named "composite momentum".
It has been developed by an italian technical analyst. I have the code for metastock and prorealtime:

-COMPOSITE MOMENTUM PER METASTOCK-

Key
FORMULA

MOM:=Mov((Mov(C,3,S)-Mov(C,9,S)),1,E) / Mov(C,3,S) *100;
Mov(
((Ref(Sum(If(MOM>Ref(MOM,-1),MOM-Ref(MOM,-1),0),5),-1)-
(Ref(Sum(If(MOM>Ref(MOM,-1),MOM-Ref(MOM,-1),0),5),-1)/5)+ If(MOM>Ref(MOM,-1),MOM-Ref(MOM,-1),0)) /
(Ref(Sum(Abs(MOM-Ref(MOM,-1)),5),-1) -
(Ref(Sum(Abs(MOM-Ref(MOM,-1)),5),-1)/5) + Abs(MOM-Ref(MOM,-1)))*100) -
Abs(
((Ref(Sum(If(MOM<Ref(MOM,-1),MOM-Ref(MOM,-1),0),5),-1)-
(Ref(Sum(If(MOM<Ref(MOM,-1),MOM-Ref(MOM,-1),0),5),-1)/5)+ If(MOM<Ref(MOM,-1),MOM-Ref(MOM,-1),0)) /
(Ref(Sum(Abs(MOM-Ref(MOM,-1)),5),-1) -
(Ref(Sum(Abs(MOM-Ref(MOM,-1)),5),-1)/5) + Abs(MOM-Ref(MOM,-1)))*100))
, 3, E)

XTL quarterly expl
FORMULA
(Mov( Stoch(5,3),3,S))*2-100

Composite momentum
FORMULA
Mov((Fml( "Key") + Fml( "XTL quarterly expl"))/2,2,W)

this is a picture of this oscillator....it seems really clear:

Thanks for sharing kantkant2, hopefully this would trigger interest in the conversion process - you could also give the Derivative Osc I've posted from Constance Brown in the sharing, it should be coming close and it's pretty smooth as well while keeping lag low.

Hi KantKant2,

Would you please post a link describing in words what this indicator does?

Thanks

Dear all,

I built my first indicator for NT and, if possible, I would like someone looked at it as I have two problems.
I wouldnt know which thread to use so I picked the momentum.

This indicator should give the Weakness Index as given by Willain in his book. The problems are:
1) I did apply it to a chart and it plotted and then it stopped plotting. I attach the ES's from yesterday.
2) It would only plot the (Close[0]-Close[1])/Volume[0] , which is the inverse of the Weakness Index, but not the Volume[0]/(Close[0]-Close[1]).
Can anyone shed some light and help me?

I attach the .cs and the charts of yesterday's ES with the "inverse" Weakness Index plotted together with a volume and another chart where the Weakness does not plot anymore.
Given my very low programming skills, I do apologise in advance if I make anyone's brows raise.

Regards

Sorry, here are the attachments!

Good morning Michael, it looks like you're missing this check here in your script :

http://www.ninjatrader.com/support/forum/showthread.php?t=3170

You would see a log tab error on the Control Center likely too, this is always a good first place to check if you run into anything unexpected...

[michael fantoni]

Good morning to you Bertrand and thank you for your reply

I paste the bit which is confusing me

protected override void OnBarUpdate()
{if(CurrentBar==0)
{
difference.Set(Input[0]);
volume.Set(Input[0]);
Value.Set(Input[0]);
}
else
{
difference.Set((Close[0] - Close[1])*1000000);
volume.Set(Volume[0]);
double weak = difference[0]/volume[0];
Value.Set(weak);
}}

I added the extra bit. The point is that this indicator plots if I set
double weak = difference[0]/volume[0]

but it doesnt if I set
double weak = volume[0]/difference[0]

and it was doing this already. If it was a problem of missing bar count shouldnt it matter whichever way I use the indicator?

I attach the 6E

Michael, what error are you then seeing if you set it to the second option? It could be a different issue you encounter then, like a division by zero for example.

[michael fantoni]

Thats the thing! there is no error at all. It compiles just fine, without any error, both version. But one plot the other doesnt. If it was a division by zero then one should be 0/something and the other should be something/0, that is inifinity. U see the riddle (at least to me)?

[NinjaTrader_Bertrand]

Hi Michael, I was not referring to a compile error shown in the editor, but a error seen at runtime of the script, those would be shown in the Control Center > right most Log tab. Would you spot anything there as the variation giving your issues is applied to the chart?

[michael fantoni]

Ah, I see! sorry!

yep, just checked it. The one that does plot, difference/volume, doesnt show any error whereas the volume/difference shows a "Value outside range", like u originally said: most likely is some range value not available. but why does it do for one and not for the other? If the value is outside some range should be for both calculations? So the fix I added is not working then.

[NinjaTrader_Bertrand]

The fix you added works - there's a plot now and no issues on CurrentBar == 0 as you would not reference one bar back here.

But another issue came up, which is generating a plot value outside of the valid range...I suspect your division 'blowing up' here. You would need to debug the value generated here via Prints, they should still go to the output window in such cases as they are only non suitable for the Plot() method.

[michael fantoni]

Thank you very much Bertrand!

I will check this debugging thing.
