Hi, I'm trying to compute a moving average of length 20. I've got a vector of structs that's read into my function and I'm using an iterator to read through as follows: int length = a; int count = 0; double sum = 0; while (itr!= priceinput.end()) { sum += …

Hi, I'm wondering what could cause this type of runtime error: My program basically reads data from different kinds of data files, either a minute data file or a 5 minute data file and then does some analysis. When I run the program on the 1 min data, no problem. …

Hi, I'm new to APIs. Got the code below to compile (with 3 warnings C4129) but it won't output to the designated path. I created the txt file ahead of time, nqquotes.txt, but after the code compiles, that file stays empty. Thanks for your help, TR #include "stdafx.h" #include <tchar.h> …

Hi All, Well I've been stuck for a while here. I'm trying tp write a function called TransfertoSwingID which will transfer a line of data held in a struct contained in a vector to a new vector of structs. Basically as I'm iterating through the vector of structs called "prices", …

Hi, I've got a vector of structs populated with the following fields: double double double double (unsigned int) (unsigned int) string I want to take each line in that vector (call it OldVec), and 1. transfer it to a new vector of structures 2. add a string identifier at the …

Hi, Imagine a vector of structures with each structure containing various variables. struct Data { double x double y double z } vector<Data> Dataset vector<Data>::iterator it //input some data from a file into DataSet How can I iterate over this vector, comparing say, x at the nth row to the …

Hi, I've got stock market data in a structure as follows. [CODE]struct PriceInfo { double Open; double High; double Low; double Close; unsigned int Volume; unsigned int Time; std::string Date; };[/CODE] My program imports the data from a csv file and stores it in memory etc. The date and time …

Hi everyone, When I try the code below with data in a txt file, I have no problems and the data prints properly and neatly on the screen. (Note, one slight modification when using a txt file, instead of getline (ist, ignored, ','), I do getline (ist, ignored, '/t') to …

I have some stock market price data organized as follows in a structure: struct PriceInfo { string Date; unsigned int Time; double Open; double High; double Low; double Close; unsigned int Volume; }; This struct organizes price data per interval of date and interval of time, where time is measured …

Hi, I have a csv datafile with stock price data that I've read into a vector of structures that looks like this: 09/11/2009 9.30 open, high, low, close, volume 09/11/2009 9.31 o, h, l, c, volume and so on to 09/11/2009 16.14 o, h, l, c, volume //next day starts …

I'm reading a big csv file into a data structure defined as such: [CODE]struct PriceInfo { double Open; double High; double Low; double Close; unsigned int Volume; unsigned int Time; std::string Date; };[/CODE] So somewhere in my main function, I have this line: // read contents of datafile by overloading …

Hi, The following code I've been working on (as hobbyist) compiles okay, buy at runtime it fails to output the dates that it is supposed to extract from a csv file. I've been staring at this forever and no progress. I am thinking that the problem occurs before the date …
