OK, I have worked on this project for 24 hours without success, it is time to ask for help
Problem, import data is successful but chart does not display the data series
Method used:
I have created a synthetic continuous daily price data set in a text file about 5 1/4 years long. It now imports successfully.
ex. of format 20070322;12439.72;12532.03;12352.21;12455.14;10
This is standard date, OHLC and volume.
See footnote below about the last field
As this is a synthetic data set of a price series it wont be listed on any exchange,
In Instrument manager, set these parameters.to create an instrument in NT
Available master instruments> Click new button to create new instument
2 sections
: 1st is definition
I gave it a name DOWSN and also came back later to additionally create the name DSN to try it this way too.
Template set from 24hr to US equities RTH
For Exchange: Later NT requested I need an exchange, so Default
and NYSE selected
2nd is Misc:
skipped commission
next symbol map; this is confusing here as this is a synthetic index.
Past this step I got an error message requesting a map
to the above symbol....Multiple selections are allowed....selections
external is most relevant and TT ,,,my data feed,, also selected in
case NT looks for this
The instruments DOWSN and DSN added to instrument list to the left on instrument manager.
I have set the above as such because I have found no documentation for how to handle the elements that raise questions to the above case. Such as how long can an instrument name be for a particular exchange. Or how to set an exchange for a synthetic data set.
In historical data manager > Import
Format: NT ....end of bar time
Bar type...Last
Time zone.... For Daily data I have found any setting UTC or my local time works.
Click Start import
A selection box comes up with the Import file for the data set described above.
The data text file as above must be placed in NT>Import found in MYComputer>
MYDocuments. It must be named Textfile.last.txt... In this case DOWSN.last or
DSN.Last.
Choose the test file as above and click Open
A dialog box comes up that import was successful..
Make a Chart
Go to Flie>New>Chart ...A Data Series box comes up
Choose DOWSN and Click New
Adjust the days data to load under data
Click OK
************************************************** ********
This is the Location of the problem.
A Blank chart comes up with a price range of 0 to .01
************************************************** *********
How do I get a chart to show this synthetic data file I have made.
No tinkering to the above will get a chart with data to come up
Including the footnote below
footnote/////\\\\
after completing downloading or importing data, NT must be closed and then reopened to show the new data.( accept if the data is downloaded and it is already
the next day).
Footnote on data format:
The last field ";10 " as in above example must contain data.. Without it the import function would not work. It did not work with just ; or ;0
