Problem plotting OrderFlowVWAP

[Kicks.Spin]

error CS0029 on line 69 failing to plot OrderFlowVWAP. attached code shows simple plot of a sma. added coding of exact same form for OrderFlowVWAP. but can not convert type double to OrderFlowVWAP. What am i doing wrong? thanks!

Hello Kicks.Spin,
Use below:

OrderFlowVWAP1 = OrderFlowVWAP(VWAPResolution.Standard, TradingHours.String2TradingHours("CME US Index Futures RTH"), VWAPStandardDeviations.None, 1, 2, 3).VWAP;

You should define Series in State.DataLoaded, hope it helps!

thanks for your response s.kinra. the attached code does define series in State.DataLoaded. It is commented out because it generates error. i can not export ninjascript add on with a compile error. so that why commented out. how to get a compile/plot? thanks

Hello Kicks.Spin, thanks for writing in.

Your code is not implementing the OrderFlowVWAP properly. Please see the example on the documentation page:

https://ninjatrader.com/support/help...flow_vwap2.htm

First, a 1 tick series needs to be added in State.Configure.

[B]else if (State == State.Configure)[/B]

[B]{[/B]

[B] AddDataSeries(Data.BarsPeriodType.Tick, 1);[/B]

[B]}[/B]

After this, initialize the object in State.DataLoaded:

OrderFlowVWAP1 = OrderFlowVWAP(VWAPResolution.Standard, TradingHours.String2TradingHours("CME US Index Futures RTH"), VWAPStandardDeviations.None, 1, 2, 3);

Then you can access the values in OnBarUpdate e.g.

protected override void OnBarUpdate()
{

if (CurrentBars[0] < 0)
return;

if(BarsInProgress == 0)
{
    Print(OrderFlowVWAP1.VWAP[0]);
}

if(BarsInProgress == 1)
{
    OrderFlowVWAP1.Update();
}

}

Please let me know if I can assist any further.

hello kinra: this compiles with prints to troubleshoot. can you look? there is some sort of conflict with .VWAP type and OrderFlowVWAP. regards,

[s.kinra]

Hello Kicks.Spin,
You need to print as below:
Print(string.Format("{0} CurrentBar | {1} OrderFlowVWAP1, {2} HMA", CurrentBar, OrderFlowVWAP1.VWAP[0], HMA1[0]));
Also include the changes as suggested by Chris i.e. add tick series & use barsinprogress to update vwap as shown by Chris.

i tried to implement your code suggestion but failed to compile. my goal is to write an indicator (not a strategy) that plots VWAP for the RTH during RTH otherwise plot VWAP for a custom night session i created. line 87 compile error in properties section. "indicator already has a definition for VWAPSessions" what am i doing wrong to fail to plot? thanks. code below.

Hello,
My observations:

1. Before OnStateChange, you should initiate as "private OrderFlowVWAP VWAPValueRTH;" for all similarly.
2. In DataLoaded, define all 3 initiated above, you are defining only 2 currently.
3. For Plots you should not use any names used above, currently you are using VWAPSessions which you initiated already so the error.

Fix it & see if it works for you. Hope it helps!

id did that. still not working. why are three initiations required? there are only two VWAP sessions which need initiation. we just need to select one and plot that. so i did this and failed. can i go back to the well one more time here. i am missing some fundamental i think

public class OrderFlowVWAPSessions : Indicator
{
private OrderFlowVWAP VWAPValueRTH;
private OrderFlowVWAP VWAPValueON;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"RTH and ON VWAP calcs";
Name = "OrderFlowVWAPSessions";
Calculate = Calculate.OnBarClose;
IsOverlay = true;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;

AddPlot(Brushes.Orange, "VWAPSessions");

{

VWAPChoice = OrderFlowVWAP(VWAPResolution.Standard, TradingHours.String2TradingHours("CME US Index Futures Evening Session (MLR)"), VWAPStandardDeviations.None, 1, 2, 3);


}

You must understand what you're doing.
Earlier you initiated 3 & defined 2, now you initiated 2 & defined 3, how do you think it will work?
I am not suggesting anything, I just asked you to correct it. You need to know if you need 2 or 3.
Please note, if you are initializing 3 you must define 3 & if you are initializing 2 you must define 2.

Nailed it. I get it now. Thanks for your patience and direction. Sleeping helps too. lol The attached code calcs OrderFlow VWAP for RTH and night sessions separately. It uses a custom overnight trading hours session i defined. idk how to upload that. Anyone is welcome to use this, but you pry get a compile error until a custom trading session defined. Let me know if you have any pointers on the logic. Regards
