EasyLanguage to NinjaScript

[RobinT]

In case I am not being clear:

Tradestation does it:

ChartingHost.ScrollTo (dtObj);

where dtObj is a DateTime.

and Multicharts:

scrolltobar ( BarNumber ) ;

where barnumber is a number of bars ago (same as GetBar (dtObj) )

Do you know how I can automate data import. If I provide a txt file with the updated historical data, how can I automate historical data import.

Hello RobinT,

There is no function or method to scroll to or move to a set point on the chart in NinjaScript. An automated import of the historical data would not be supported within NinjaScript.

[RobinT]

I just want to make sure my data is up to date before i start processing.

[RobinT]

Is there a recommended place to put output files generated by the indicator.

[RobinT]

Environment.GetFolderPath(Environment.SpecialFolde r.MyDocuments);

[NinjaTrader_PatrickH]

RobinT,

There are no recommendations on where to place the files.

You can use our reference samples as a guide for StreamWriter and System.IO functions: http://ninjatrader.com/support/forum...splay.php?f=30

Right click in your chart > select Data Series > select Custom Range under Load Data Based On > set the desired Start and End Date > OK.

Can the amount of data loaded be controlled by Ninjascript and can I find out the screen resolution or bar spacing?

Hello RobinT,

The amount of data would be controlled by the chart. Screen resolution and bar spacing would require unsupported code.

[RobinT]

where would I find this unsupported code.

[RobinT]

Can you suggest a way of doing this:

value61 = LowestBar(Low, 4);

but if bar 0 is the lowest I want the next lowest. TS has a nthlowestbar function and I wondered if NT has an equivalent. How can I use indexing or how can I find the lowestbar of [1], [2], [3].

wrote my own.

I dont seem to be able to display ES 03-16 before 12/11/15 even thogh I have 1 minute historical data going back to 12-30-14. I have SPX data for the same period and it displays ok. What am I doing wrong?

[RobinT]

if I import the same data as SPY it works ok. Is there some restriction for futures?

I would not have this code on hand.

You could use two loops in the following fashion:

			int first = 0;
			int second = 0;
			int period = 20;
			double low = Low[0];
			
            for (int i = period; i >= 0; i--)
			{
				if (Low[i] < low)
				{
					low = Low[i];
					first = i;
				}
			}
			low = Low[first+1];
			for (int i = period + first; i >= first; i--)
			{
				if (Low[i] < low)
				{
					low = Low[i];
					second = i;
				}
			}

Who are you connected to when you attempt to load the futures data? How far back does the data go?
