This is so that the // multiple instances of the indicator used by other charts or EAs // dont fight with each other (Error code 4103) // - Fixed deleting OBJ_TREND, only deletes its own Trend Lines // objects instead of all OBJ_TREND objects // - Fixed deleting OBJ_TEXT, only deletes its own Headlines // instead of all text // - Made file name global and indicator now deletes the xml file // each time the indicator is put on or removed from chart. Fixed // one case of divide by zero where multiple charts indicator is // on was trying to overwrite the same file (forces a new // download of the xml) // // 4/29/2007: Derk Wehler // - Fixed problem where indicator returns zero for "Minutes Until // Next Event" when there are no more events for the week for // that currency pair. That caused EAs calling it to think that // it was always new time. Instead, we now set it to a flag // value, which EAs can test for. // // 5/16/2007: Derk Wehler // - Added sample code to header // - Changed variable name from DispOldNews to DispVertNews // // 6/02/2007: Derk Wehler (thanks to "Flourishing") // - Changed how often it updates the file from the FF site web // page. Now it uses a global variable, so that when you have // it running on multiple charts, it should only update once // every 4 hours for all of them. // // 6/05/2007: Derk Wehler // - Fixed logHandle error by resetting to -1 when closed // - Added "NeedToGetFile" variable for getting the XML if it // does not already exist // - Added extern "SaveXmlFiles", so that when FFCal de-inits, // the user can choose whether or not to delete old XML files // //============================================================================= //+---------------------------------------------------------------------------+ //| WinInet.mqh | //| Paul Hampton-Smith | //| paul1000@pobox.com | //| | //| This include has been adapted from the groundbreaking GrabWeb script | //| developed by Adbi that showed me how to import functions from wininet.dll | //|---------------------------------------------------------------------------| //| grabweb.mq4 | //| Copyright © 2006, Abhi | //| http://www.megadelfi.com/experts/ | //| E-mail: grabwebexpert{Q)megadelfi.com | //| fix my e-mail address before mailing me ;) | //+---------------------------------------------------------------------------+ /* IDEAS FOR ADDITIONS: * A text lable of what the news was and when it was, e.g "USD CPI m/m @ [broker time here]" at the top or bottom within the shaded area. * Label the number of pips it went in its initial direction and how much it retraced...of course you'd have to come up with a convention for measuring movement.
