maison6579 · Postby **maison6579** » 28 Apr 2022

I notice the multicharts 14 new features.

one of these is
"
PowerLanguage: Improved the operation of “Recalculate” keyword in Portoflio Trader. “Recalculate” command will recalculate the whole portfolio now. Also, variables of RecalcPersist type are no longer supported in Portfolio Trader.

Is there any more information about recalculate command for portfolio trader?
such as,
how to use recalculate command in PT ?
is it suppored in strategy signal only (left part of PT) or in money management signal only (right part of PT) or both ?

Thanks.

Hi maison6579,

You may want to test this sample script in Portfolio Trader

Code: Select all

Var: ReCalcPersist recalc_once(True);
// do not use recalcpersist in portfolio, it only works in charting
Var: pf_recalconce(true), gvVal(0), gvErr(0);
var: vo10(0); 
const: portfolioAppType(10);

If LastBarOnChart Then Begin 
    Print ("Last bar volume = ", Volume); 
	if (getappinfo(aiapplicationtype) <> portfolioAppType) then begin
		    If recalc_once Then Begin 
		        Print ("Recalculate study!"); 
		        recalc_once = False ;
		        ReCalculate;
		    End; 
	end
	else begin
		pf_recalconce = pmm_get_global_named_num("RecalcOnce") = 0;
		    If pf_recalconce Then Begin 
		        Print("Recalculate portfolio strategies!");
		        pmm_set_global_named_num("RecalcOnce", -1);
		        ReCalculate;
		    End; 

	end;
end;

It can be called from any part of PT.

Thanks Svetlana for this reply.

However, I find a bug about this recalculate feature.

The portfolio trader(PT) recalculate-command works.
However, The right side information of PT , including (position, open P/L, even the Custom Text) could not refresh again after the recalculate is done.
The weird thing is that I add some print code and it still runs silently in the background.

We have reproduced the issue: the calculation works, but it is not displayed in the GUI. Sorry for inconvenience. Our engineers will work on improving this behaviour to include the fix in one of the future versions.
