help easy language indicator to ninja script

[noy_cabildo]

Hello guys,

This is a TS indicator that creates and update ascii data file in real time as new data appears on the TS chart. Is it possible to convert this into a NT script ?

{This file is source code for the Easy Language interface to DT. }

Vars:Directory("C:\DTTSDATA"),Interval(" "),FileName(""),x(0),wParm(0),ThisVolume(0),Count( 0),LastDate(0),LastTime(0),fname("");

definedllfunc:"C:\dttsdata\DTTS.DLL",int,"SendData ",float,lpstr,lpstr,lpstr,float,float,float,float, float,float,float,float;


ThisVolume = Ticks;

if barnumber = 1 then
begin

if DataCompression = 0 then Interval = NumToStr(Highest(upticks + downticks,5),0);
if DataCompression = 1 then Interval = NumToStr(BarInterval,0);
if DataCompression = 2 then Interval = "Daily";
if DataCompression = 3 then Interval = "Weekly";
if DataCompression = 4 then Interval = "Monthly";

fname = MidStr(getsymbolname,+0,3)+ MidStr(getsymbolname,+5,7) + "_"+Interval+"."; {name & extension only}

if DataCompression = 0 then fname = fname + "dtt";
if DataCompression = 1 then fname = fname + "dti";
if DataCompression = 2 then fname = fname + "dtd";
if DataCompression = 3 then fname = fname + "dtw";
if DataCompression = 4 then fname = fname + "dtm";

FileName = Directory + fname;

Input: cf(4);

FileDelete(FileName);
FileAppend(FileName,"cf= " + NumToStr(cf,0) + newline);
if DataCompression = 0 then FileAppend(FileName,"ticks= " + Interval + NewLine);
if DataCompression = 1 then FileAppend(FileName,"min= " + Interval + NewLine);
if DataCompression > 1 then FileAppend(FileName, LeftStr(Interval,1) + NewLine);
FileAppend(FileName,"DATE TIME OPEN HIGH LOW CLOSE VOLUME" + NEWLINE);

for x = MaxBarsBack downto 1
begin
ThisVolume = iff(DataCompression =0,Upticks[x] + DownTicks[x],Ticks[x]);
fileappend(FileName,numtostr(date[x],0) + " " + numtostr(time[x],0) + " " +
numtostr(open[x],4) + " " + numtostr(high[x],4) + " " + numtostr(low[x],4) + " " + numtostr(close[x],4) + " " +
numtostr(ThisVolume,0) + newline);
LastDate = Date; {Date & Time of last whole bar stored in file}
LastTime = Time;
end;
end;

wParm=BarStatus(1); {NOTE: Does not return 0 for opening tick as specified in docs!}

if wParm = 2 then
begin {Last Tick Of Bar, print new line}
fileappend(FileName,numtostr(date,0) + " " + numtostr(time,0) + " " +
numtostr(open,cf) + " " + numtostr(high,cf) + " " + numtostr(low,cf) + " " + numtostr(close,cf) + " " +
numtostr(ThisVolume,0) + newline);
end;

if LastBarOnChart then
begin
if (wParm<>2 or (date <> LastDate) or (time <> LastTime)) then {we're not duplicating last bar in file}
value1 = SendData(wParm,MidStr(getsymbolname,InStr(getsymbo lname,":")+1,20),Interval,fname,Date,Time,Open,Hig h,Low,Close,ThisVolume,OpenInt);
end;

Hello Noy,

Thanks for your post.

It is likely that this TS script could be converted to a NinjaScript indicator for NinjaTrader 8.

That said, in the support department at NinjaTrader it is against our policy to create, debug, or modify, code or logic for our clients. Further, we do not provide C# programming education services in our support. This is so that we can maintain a high level of service for all of our clients as well as our partners.

My advice is to start by creating as much of the indicator as possible in the Indicator Builder. This will create the framework of the NinjaScript indicator.

To create a NinjaScript indicator, open a New > NinjaScript Editor window, select the '+' tab at the bottom of the Editor window, and select 'New Indicator'. You could set up as much of the indicator as possible in the Indicator Builder.

Then, you could open the TS documentation and the NinjaTrader 8 help guide to compare which NinjaScript methods and properties are equivalent to the TS methods/properties used in the code you shared. The majority of code supported by NinjaTrader is included in the help guides.

Below is a link to a forum post with helpful information about getting started with NinjaScript.

Here is a link to our publicly available training video, 'NinjaScript Editor 401', for you to view at your own convenience.

Let me know if I may further assist.

Thanks Brandon for the quick reply, can you please point to any easylanguage to NT script conversion services.

Regrads,

Hello Noy,

Thanks for your note.

I am not aware of any EasyLanguage to NinjaScript conversion services that are available.

You could consider reaching out to vendorsupport[AT]ninjatrader.com for a list of affiliate consultants who would likely be happy to create this script or any others at your request.

Or, you could do a quick Google search for something like 'EasyLanguage to NinjaScript conversion' to find third-party developers that convert code.

Let me know if I may assist further.

Hello Noy,

Thanks for your note.

I am not aware of any EasyLanguage to NinjaScript translation services available.

That said, I see you have multiple compile errors after using the translation service you mentioned. You must resolve each compile error that appears for the script to be usable. You would need to ensure that you have the correct amount of opening and closing parentheses '( )', the correct number of opening and closing curly braces '{ }', the correct number of quote marks " "', have class-level variables set up when they are needed, and more.

Something you could do is thoroughly review each individual line of code for any syntax issues, such as missing parentheses, curly braces, or quotation marks, and add the missing item to the script. Then you could review the remaining errors by checking the compile error to see which lines of code are throwing errors.

If you have questions about what a specific compile error means, you could do a quick google search for the error in question to find out how to resolve it, such as 'compile error Identifier expected C#'.

See this help guide page for information about Debugging your NinjaScript Code: https://ninjatrader.com/support/help...script_cod.htm

Below is a link to a forum post that demonstrates how to use prints to understand behavior.

I can convert this from EasyLanguage to NinjaScript.
