Hello ... Whichever link I am using, sc.HTTPResponse always remains empty. Am I missing something? sc.MakeHTTPRequest("http://www.sierrachart.com/ACSILHTTPTest.txt"); sc.AddMessageToLog(sc.HTTPResponse, 1); |

I tried a test page on a local server (same computer), and the response remains empty as well. In other words, it's not a firewall issue. |

sc.HTTPResponse is set sometime later after the study function returns when the server responds.

You mean there has to be a pause/sleep after sc.MakeHTTPRequest? I solved my problem by installing wget on my system and making a system(wget "http://link" -O file.txt) call and then read the file. This has the added advantage that you can collect data for multiple time frames (multiple wget calls) within the same cycle. If I understand it well from other discussions, sc.MakeHTTPRequest can only be used one time. |

For users interested to download their own data, WinExec(wgetCall, SW_HIDE) works better than system(wgetCall) because it hides the prompt. SCString wgetCall="c:/sierrachart/wget/wget \"https://www.yourlink.com?function=TIME_SERIES_INTRADAY&datatype=csv&symbol=AAPL&interval=5min\" -O c:/sierrachart/data/wget.txt"; //system(wgetCall); WinExec(wgetCall, SW_HIDE); |
