Re: [amibroker] signal type

["Ara Kaloustian" <ara1@xxxxxxxxxx>]

Ed, I have not used the CBI, but I beleive there is only one ranking parameter - PositionScore.

 

How about separating the trending from choppy signals before processing.

 

Example:

 

You already know which signals were derived under what conditions... so how about doing this:

 

if (sigtype ==1)

{

PositionScore = your type 1 parameter;

}

else

{

PositionScore = your type 2 parameter;

}

 

Again, I have not done this, but worth looking into. CBI may support this structure

hi Ara,

 

what I like to do is use different type of signals in 1 system. I want to combine signals that are sensitive for trending markets (type 1) and those that are sensitive for choppy markets (type 2). When I rank these signals Amibroker will rank them as one bunch of signals. Say I have 20 signals of type 1 and 20 op type 2 then I want to tell Amibroker to rank these 2 types separately and depending on the market condition divide my money amongst the two types. 

 

In the CBI this would be possible. I just have to be able to label the signals of which type they are. To my knowledge this is not possible. In the CBI I need to be able to retrieve whether I am dealing with the choppy market signal or the trending market signal.

 

Is this possible or will I need to add this as a request in the feedback center?

 

rgds, Ed

Ed,

 

I am not sure what the issue is.

 

A signal type, the way I would define, would be based on its criteria.

 

For example:

 

BullishLongPeriod  = Criteria(LongPeriod);

BullishShortPeriod = Criteria(ShortPeriod);

hi

 

as far as I know one can not define a signal type in Amibroker, am I right?  What I mean is that I am working with systems that have multiple signal types:

 

for instance:

 

signalType1 = ....;

signalType2 =....;

signalType3 = ....;

 

Buy = signalType1 OR signlType2 OR signalType3;

 

I would like to add to this signal what type of signal it is for ranking purpose. This way I can rank the different signal types separately.  You can use a different ranking algorithm for each signalType but in the end the backtester will put all signals together and choose the best ranking ones. If one uses different algoritms then ranking will not work properly. One will have to rank them seperately but then you have to be able to retrieve what type of signal it is in the CBT,

 

any ideas?

 

thanks, Ed
