i need help to print numbers as strings, and with the correct number of decimals.

[rtwave]

people with nt,


i have been trying for a number of weeks now to get nt to generate text files as logs for events of interest. i received very little assistance from nt support but i have continued to work hard on this objective and have been able to make good progress. actually, i have been watching videos and going though microsoft's courses to learn to code in c# and it has been very helpful for this matter.


at this point i have been able to get streamwriter to work acceptably in nt.

[INDENT]private void recordevent ( string filepath )     [/INDENT][INDENT]{[/INDENT][INDENT] [/INDENT][INDENT=2]filepath = string.Format(@"{0}ntlogs {1} {2} {3} {4} {5}.txt", Pridir, Symtic, DateTime.Now.ToString("yyyyMMdd HHmmss"), Castyp, Close[0]);[/INDENT][INDENT=2]
Print(filepath);
sw = new StreamWriter(filepath);  
sw.AutoFlush = true;  
sw.WriteLine(message);      
sw.Close();   
[/INDENT][INDENT]}[/INDENT]

from everything i have studied, it seems to me that nt implicitly converts the number Close[0] to string in the fragment above as it has been working correctly for me.


however, there are several other numerical inputs and variables (some are integer, some are decimal type) i want to be able to print to my text files using this same string.Format(@"...", method. in these cases, implicit conversion by c# will not be good enough. ¿how can i command nt to convert decimal or integer values to string? ¿and very importantly, how can i define the number of decimals that will be printed? ¿and, is it possible to define the number of decimals to be printed as a user defined input instead of hard coding it?




very well, i hope i will receive far more effective assistance from nt support this time. thanks, regards.

Hello rtwave,

While the NinjaTrader staff cannot debug a script on your behalf or write code for you, we can detail how documented NinjaScript items work.

I do have an example that writes bar information to file that you may use as an example.

https://ninjatrader.com/support/forum/forum/ninjatrader-8/strategy-development/100192-comparing-real-time-historical-and-replay-performance#post100192

To convert an integer to a string use <int>.ToString().
To convert a double to a string use <double.ToString().

This would fall under general C# and is not specific to NinjaScript. Integers, doubles, and strings are all common to C#.

I hope you understand that no one will write and compile code for you? On this forum there are a huge number of articles, which describe in detail how to solve this problem. I can't throw off the link, because I don't remember when I saw that post. I had a similar problem, I needed to display the numbers of 500 random numbers in the range from 0 to 10000. Each time the maximum number that was displayed was 244. I don't know what it was connected with, but now this is my least favorite number, although it has a very cool value which you can find out about here https://www.sunsigns.org/angel-number-244-meaning/. The only thing that helped me was to completely rewrite the entire code, slightly changing the algorithm ..
