RawTextOutput should be called AFTER ProcessTradeSignals, was: ...wrong row

Hi all, I am trying to implement a CBT for limit entries and to get the limit and low prices for all entry signals on a bar by bar basis in the detailed log. I am using bo.RawTextOutput to get the low prices and limit prices for all entry signals. The issue is that the RawTextOutput is coming on the bar/date before the signal bar. _Trace is working fine and shows the output in the correct bar. The screenshot and code is below, please let me know what I am doing wrong:

BuySignal		 = AboveMinInc;

Buy				 = Ref( BuySignal, -1 );

LimitPrice		 = IIf( Buy, Ref( C, -1 ) * 99/100, 0 ); // below 1% of yesterday's close
BuyPrice		 = IIf( Buy, Min( O, LimitPrice ), 0 );

// CBT for Limit Entries
SetBacktestMode(backtestRegularRaw);
SetOption("UseCustomBacktestProc", True );

if( Status("action")== actionPortfolio ) 
{ 
    // retrieve the interface to portfolio backtester 
     bo = GetBacktesterObject(); 
     bo.PreProcess();    //  Do pre-processing (always required)
     
     DetailedLog = GetOption("PortfolioReportMode") == 1;

	for (i = 0; i < BarCount; i++) // Loop through all bars
	{
		PosQty = bo.GetOpenPosQty();
		_TRACE("[AB] Day ------ " + i);
		_TRACE("[AB] Open Position: " + PosQty);
		Count = 0;
		
		for(sig=bo.Getfirstsignal(i) ; sig ; sig=bo.GetNextSignal(i))
		{
			LowPrice = Foreign( sig.Symbol, "Low" ); //grab the low to check limit order fill
			if( sig.IsEntry() )
			{
				if (DetailedLog) 
					bo.RawTextOutput("\t " + sig.Symbol + " LowPrice: " + LowPrice[i] + " LimitPrice: " + sig.Price );
				
				_TRACE("[AB] " + sig.Symbol + " LowPrice: " + LowPrice[i] + " LimitPrice: " + sig.price);
				
				if( Count > 2 - PosQty OR LowPrice[i] > sig.price) 
					sig.Price=-1;
			}
			
			Count++;
		}
		
		bo.ProcessTradeSignals(i);
	}

    bo.PostProcess();    //  Do post-processing (always required)
}

In the below screenshot the extra lines should come under 3/2/2017 rather than 3/1/2017

Program and RawTextOutput function work 100% correctly.

Your code is wrong

You should put RawTextOutput AFTER ProcessTradeSignals.

It is so because ProcessTradeSignals call indicates that you are processing given bar and it produces NEW entry in "Date" column. Everything what you do BEFORE call to ProcessTradeSignals belongs to PREVIOUS bar.
