Amount of Bars, which is added by Add()

[NinjaTrader_Joydeep]

Hello agafon2,
We provide support for documented NinjaScript codes only and this is more of a C# query which is unfortunately beyond what we could support.

I will however leave the thread open for our forum members who can share their valuable inputs.

Hello, Joydeep

Please, help me

To write some data to binary file i use:

               using (FileStream stream = new FileStream(History_way+"EURUSD"+i_period+".hst", FileMode.Append)){                    
                 using (BinaryWriter writer = new BinaryWriter(stream)){
 
                   writer.Write(Open[0]);   
 
                   writer.Close();                            
                 }
               }

But if i use a code above, other programes can't open this file in a Read mode

How to make a code, where i can open binary file in NinjaScript and in other programes in one time?

Hello agafon2,
If you define the start and end parameter as time then are you able to do it. Please refer to this overload to do it.

DrawLine(string tag, bool autoScale, DateTime startTime, double startY, DateTime endTime, double endY, Color color, DashStyle dashStyle, int width)

Hello agafon2,
If you try using 2 plot values (each with different color and set the plot style to Bar) then are you able to do it.

Hello agafon2,

Can you please give a code example of indicator

[NinjaTrader_Joydeep]

Hello agafon2,
If you try the below code then are you able to make it work.

//in Initialize
Add(new Plot(Color.FromArgb(100, Color.Green), PlotStyle.Bar, "Plot0"));
Add(new Plot(Color.FromKnownColor(KnownColor.Blue), PlotStyle.Bar, "Plot1"));

//in OnBarUpdate
Plot0.Set(1);
Plot1.Set(-1);

What is an order of calling streams, when we use multi-series indicators:

Here is a code:

        protected override void Initialize()
        {
            Overlay                = true;
            Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Last);    //1        
            Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Bid);    //2    
            Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Ask);    //3            
            
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
            
          if (BarsInProgress == 0) {
            Print("Current TF");
          }
        
          if (BarsInProgress == 1) {
            Print("Last");        
          }
        
          if (BarsInProgress == 2) {
            Print("Bid");        
          }
        
          if (BarsInProgress == 3) {
            Print("Ask");        
          }        

        }

What is an order of calling streams? What stream will be the first, second, third e.t.c.? I mean, that OnBarUpdate() is calling for every stream: for current chart, for Ask, for Bid and for Last, i Add() this streams in Initilize() What is an order of calling? I mean, OnBarUpdate() is calling first for current chart bars or for Last bars or for Ask or for Bid?

Hello agafon2,
NinjaTrader is an event based application and the OnBarUpdate event will be triggered when there is a new quote for the bar series.

Thus NinjaTrader parse does not controls it, it is more of market driven.

Joydeep, sorry, you didn't understand me:
When you start an indicator at first time, every history bar analyse and OnBarUpdate is calling for every history bar, while Historical == true;

And if i use extra streams,adding by Add(), what is an order of separating OnBarUpdate function calling for every stream?

[NinjaTrader_Joydeep]

Hello agafon2,
The bars are referenced as per time. If the primary bar and the secondary bar have the same time stamp then the primary bar will be updated first, then the 1st secondary bar and so on.

Hello, Joydeep

Look,
There is M1 chart based on Last price
Every bar of this chart contains some amount of ticks with Last price on it

Always there are two extra prices for every tick on the market: there are Ask and Bid prices

How to get Ask and Bid prices for every historical tick

I added three extra streams: Ask, Bid and Lask ticks, but i can't synhonize it

[NinjaTrader_Joydeep]

Hello agafon2,
Unfortunately the bid/ask/last data are not synchronized and you have to explicitly synchronize it. You may refer to this indicator which is on similar lines

http://ninjatrader.com/support/forum/local_links.php?action=ratelink&linkid=365&catid=-1&lpage=1

Also please do note, the highest granularity time in NinjaTrader is seconds. So you may not have a 100% sync in case you have multiple ticks on the same seconds.
