Title: Re[2]: [amibroker] Graphing beyond the data

imo, true future bars should have future timestamps, i.e. data time numbers that represent existing future dates and times. The price chart and its time stamps should remain as it is. In other words future bars should be 'added' to the chart, not shift anything. Shifting is just a work-around that works only for selected applications. 


This bring us back to the artificially created continuous DateTime array that was discussed long ago - unless I am wrong having such a function, if it could produce future dates, would solve all problems. A getDataTimeArray() would also make it easy to check data integrity, plot indicators wrt to true time and not wrt random (RT) quotes, compare data, etc.


best regards,

Hello,

 

As an example here is the formula that plots Ichimoku cloud projected in the future

 

me26=(HHV(High,26)+LLV(Low,26))/2

me9=(HHV(High,9)+LLV(Low,9))/2

me52=(HHV(High,52)+LLV(Low,52))/2

Avg26_9=(me26+me9)/2

MClose=IIf(BarIndex()>LastValue(BarIndex())-25,-1e10,Ref(Close,25)); 


Colorhist=IIf(Avg26_9>me52,colorLightOrange ,colorPaleBlue); 


Plot(me26,"M26",colorRedstyleThick); 

Plot(me9,"M9",colorBlue,styleThick); 

Plot(MClose,"H26",colorGreen,styleThick); 

Plot(C,"C",-1,styleCandle); 

H=Avg26_9; 

L=me52; 

Plot( me52,"S1"

          IIf( Avg26_9 > me52,colorOrange,colorBlueGrey),styleCloud,Null,Null,25);

No I did not miss the point. 

 

The supported way to EXTEND indicators is to calculate them as usual and

plot using XShift.  In this approach you are using LAST X bars of array

as "future" bars. Then to actually display these future bars at correct place

you use XShift.

TJ, 

 

I think you missed the point.  The problem is one of extension not shifting which Plot() cannot handle.  Extending indicators, as Robert and many of us want to do, is necessary to identify future values for a variety of studies, including Hurst channel projections, cycles, etc.  Here are TradeStation examples showing the extension of the analysis (not a shift) into the future.

Hello,


You can do that using XShift parameter of Plot() function

http://www.amibroker.com/f?plot


For coding example, see DispMA (displaced moving average)

that is shipped with AmiBroker
