unexpectet end of programm/unbalanced parentheses
- The first step is to style your code properly, or to use the automatic styler in MetaEditor. This will make it easier for you to spot problems.
- The first problem, is that you commented out your closing braces for the OnStart() function (see the text below — "//} <- Fix this by removing the "//"").
// The code below was styled with the "Allman" style void OnStart() { input ENUM_TRAIL_TYPE trailType = ENUM_TRAIL_TYPE(0); // modified input int ATRPeriod = 28; input int ATRFactor = 5; input bool show_fib_entries = true; double norm_o = iOpen(NULL, 0, 0); double norm_h = iHigh(NULL, 0, 0); double norm_l = iLow(NULL, 0, 0); double norm_c = iClose(NULL, 0, 0); //} <- Fix this by removing the "//" // Wilders moving average double Wild_ma(double _src, int _malength) { static double _wild = 0.0; _wild = (_wild == 0.0 ? _src : _wild * (_malength - 1) / _malength + _src / _malength); return(_wild); } // True range calculations void TrueRange() { double HiLo = Min(norm_h - norm_l, 1.5 * NormalizeDouble(iMA((norm_h - norm_l), ATRPeriod), _Digits)); double HRef = (norm_l <= norm_h[1]) ? (norm_h - norm_c[1]) : ((norm_h - norm_c[1]) - 0.5 * (norm_l - norm_h[1])); double LRef = (norm_h >= norm_l[1]) ? (norm_c[1] - norm_l) : ((norm_c[1] - norm_l) - 0.5 * (norm_l[1] - norm_h)); double trueRange = (trailType == ENUM_TRAIL_TYPE(0)) ? Max(HiLo, HRef, LRef) : Max(norm_h - norm_l, abs(norm_h - norm_c[1]), abs(norm_l - norm_c[1])); } // Trade logic void TradeLogic() { double loss = ATRFactor * Wild_ma(trueRange, ATRPeriod); double Up = norm_c - loss; double Dn = norm_c + loss; double TrendUp = Up; double TrendDown = Dn; int Trend = 1; TrendUp = (norm_c[1] > TrendUp[1]) ? Max(Up, TrendUp[1]) : Up; TrendDown = (norm_c[1] < TrendDown[1]) ? Min(Dn, TrendDown[1]) : Dn; Trend = (norm_c > TrendDown[1]) ? 1 : (norm_c < TrendUp[1]) ? -1 : (Trend[1] == EMPTY_VALUE) ? 1 : Trend[1]; double trail = (Trend == 1) ? TrendUp : TrendDown; static double ex = 0.0; ex = (Trend == 0) ? ex[1] : (Trend == 1) ? Max(ex[1], norm_h) : Min(ex[1], norm_l); } // Plot TP and SL void PlotTPandSL() { Plot(trail, "Trailingstop", Trend == 1 ? Green : Trend == }
3. However, now that we have fixed the closing brace, you now have 104 errors and 8 warnings ...
