Very often, customers ask the right way to combine an indicator bought on the Market into their buying and selling advisors. It is time to present a easy, dependable and feature-rich resolution. The connection instance is so simple as potential, it would permit even a novice programmer to determine it out.
That is an included class file for connecting the indicator. It’s essential put it within the “Embody” folder of your terminal.
class i_FourAverage { public: int Handle1; bool FirstStart; double Buffer1[]; bool Sign; bool DownloadsIndicator(bool& recalculation, string image, ENUM_TIMEFRAMES timeframe, int shift, int preset, int periodFA = 32, int average_1 = 134, int average_2 = 47, int average_3 = 1, int average_4 = 45, int vary = 50, int bars = 3); i_FourAverage() { FirstStart = true; Handle1 = -1; } }; bool i_FourAverage::DownloadsIndicator(bool& recalculation, string image, ENUM_TIMEFRAMES timeframe, int shift, int preset, int periodFA = 32, int average_1 = 134, int average_2 = 47, int average_3 = 1, int average_4 = 45, int vary = 50, int bars = 3) { if(FirstStart) { Handle1 = iCustom(image, timeframe, "MarketFourAverageMT5", preset, "_", periodFA, average_1, average_2, average_3, average_4, vary, 0, "_", false, 0, false, 0); FirstStart = false; } Sign = false; int shiftmulti = GetShiftMultiSymbol(image, timeframe, shift, false); if(shiftmulti == -1) { recalculation = true; return(false); } string title = "FourAverage"; if(!FillArrayFromBuffer(Handle1, 0, title, shiftmulti, bars, Buffer1, true)) return(false); recalculation = false; return(true); } int GetShiftMultiSymbol(string image, ENUM_TIMEFRAMES timeframe, int shift = 1, bool no_search = false) { if(Image() == image) { return(shift); } else { datetime time_bar1 = iTime(Image(), timeframe, shift); int shiftmulti = iBarShift(image, timeframe, time_bar1, no_search); return(shiftmulti); } } bool FillArrayFromBuffer ( int indicator_handle, int buffer_num, string title, int start_pos, int rely, double &buffer[], bool expand_and_revers = false ) { ResetLastError(); if(expand_and_revers) ArrayResize(buffer, rely); if(CopyBuffer(indicator_handle, buffer_num, start_pos, rely, buffer) < 0) { string error = string(GetLastError()); PrintFormat(TextByLanguage("Не удалось скопировать данные из индикатора " + title + ", буффер № " + string(buffer_num) + ", код ошибки: " + error + ", старт: " + string(start_pos) + ", сколько: " + string(rely), "Failed to repeat knowledge from the indicator " + title + ", buffer № " + string(buffer_num) + " , error code: " + error + ", begin pos: " + string(start_pos) + ", n: " + string(rely))); return(false); } if(expand_and_revers) ArrayReverse(buffer); return(true); } string TextByLanguage(string rus, string eng, string zh = " ", string pt = " ") { if(TerminalInfoString(TERMINAL_LANGUAGE) == "Russian" && rus != " ") return(rus); else if(TerminalInfoString(TERMINAL_LANGUAGE) == "Chinese language (Simplified)" && zh != " ") return(zh); else if(TerminalInfoString(TERMINAL_LANGUAGE) == "Chinese language (Conventional)" && zh != " ") return(zh); else if(TerminalInfoString(TERMINAL_LANGUAGE) == "Portuguese (Brazil)" && pt != " ") return(pt); else if(TerminalInfoString(TERMINAL_LANGUAGE) == "Portuguese (Portugal)" && pt != " ") return(pt); else return(eng); }
An instance is getting indicator knowledge in an skilled Advisor.
