[amibroker] LastValue()

["Ara Kaloustian" <ara1@xxxxxxxxxx>]

I use last value in my programs frequently because it is essential in RT trading.

 

I use it in this manner:

 

Debug = Param("Debug",0,0,1,1);

Trade  = Param("Trade",0,0,1,1);

 

Sel_Close = iif(Degug,SelectedValue(Close),iif(Trade,LastValue(Close),Close));

 

This allows me the flexibility of being able to debug program when in Debug mode, AND guarantee me that when in Trade mode that signals are the last value available. This prevents problems when I move the cursor around during trading and guarantees that the signals I generate are still based on last value and therefore valid.

 

Also when both Debug and Trade are off, I can do backtest.

 

Problem:  I understand that using LastValue() forces loading of entire array, potentially slowing down processing.

 

Quetion:  Is there a way around this, without losing the flexibility?

 

Thanks
