[scanner accessing data outside medved]

So i'm much better coding in nodeJS, and am wondering if i can have medved perform a localhost server request or database request or some other location i deposit market data? for example if the scan performs a get request to localhost:8080?TSQ (a nodeJS server) and have returned some JSON or XML data that can be used within the scanner/paintbar? I was also curious if an intraday scan could perform a request to medved's built-in API to retrieve daily data within an intraday scan?

[multiday FIFO Q in advanced state keeping paintbar]

So i have it working, and like you say, First and Last are the only ones giving me a result. First and Last give me the same result (Last = First). when i try to result a FIFOQ.Sum, it also just results in the same value as FIFOQ.First, and when i result FIFOQ.Count it shows 1 leading me to think the Q is clearing with each new day and only holding on the the current days value?

Mike, thanks for your help. I really like your if statement to find the first bar of the day. 

When I use the FIFOQueue I don't get any results on the scanner or in my charts. Here is what I just tried:

FIFOQueue Qvwap; FIFOQueue SQvwap;
private void PaintbarInitialize(){}
private struct PaintbarState{public DateTime SessionStart;}
private PaintbarState CurrentState;
private PaintbarState SavedState;
private void PaintbarClearState()
{
    CurrentState     = new PaintbarState();  
    FIFOQueue Qvwap  = new FIFOQueue(100);
    FIFOQueue SQvwap = new FIFOQueue(100);
}
private void PaintbarSaveState()
{
    SavedState = CurrentState;
    Qvwap.CopyTo(SQvwap); 
}
private void PaintbarRestoreState()
{
    CurrentState = SavedState;
    SQvwap.CopyTo(Qvwap);
}
public void MainCalculation(){
    var session = GetTradingSessionInfo(Timestamp);
    
    if (CurrentState.SessionStart != session.SessionStart){
        CurrentState.SessionStart = session.SessionStart;
        Qvwap.Add(vwap[1]);
    }
    
    SetColorAndShape("Line", PBShape.Rectangle, SysColor.MainIndicator2);
    SetYValue(Qvwap.Last);
    SetScanResult(Qvwap[4]+", "+Qvwap.First);
}

I am trying to code an indicator that paints the end of day vwap from the previous day as a line for the current day (on a 5 minute chart). I have managed to plot this on my chart, but cannot seem to carry forward the historical values for these lines. for example, it would be nice to have a FIFO Q(20) with the last 20 horizontal line values. Attached you should find an image of a chart with this paintbar.

private void PaintbarInitialize(){}
private struct PaintbarState{public double today;}
private PaintbarState CurrentState;
private PaintbarState SavedState;
private void PaintbarClearState()
{
    CurrentState = new PaintbarState();  
}
private void PaintbarSaveState()
{
    SavedState      = CurrentState;  
}
private void PaintbarRestoreState()
{
    CurrentState = SavedState;
}
public void MainCalculation(){

    var session = GetTradingSessionInfo(Timestamp);
    if (Timestamp == session.SessionStart){
        if (vwap[1] > .01 ) {CurrentState.today = vwap[1];}
        else if (vwap[2] > .01 ) {CurrentState.today = vwap[2];}
        else if (vwap[3] > .01 ) {CurrentState.today = vwap[3];}
        else if (vwap[4] > .01 ) {CurrentState.today = vwap[4];}
        else if (vwap[5] > .01 ) {CurrentState.today = vwap[5];}
        else if (vwap[6] > .01 ) {CurrentState.today = vwap[6];}
    }

    SetColorAndShape("Line", PBShape.Rectangle, SysColor.MainIndicator2);
    SetYValue(CurrentState.today);
    SetScanResult(CurrentState.today);

}
