I know this is long, but does anybody know how to convert this system written in Amibroker code into Metastock?
/*============================================================================== Global Settings ==============================================================================*/ SetOption("InitialEquity", 1000000); SetOption("MinShares", 50); SetOption("NoDefaultColumns", True ); SetOption("CommissionMode", 2); //$$ per trade SetOption("CommissionAmount", 0); // commission is accounted for in skid SetOption("MarginRequirement", 10); SetOption("UsePrevBarEquityForPosSizing", True); SetOption("UseCu[censored]cktestProc", True );
SetTradeDelays( 1, 1, 1, 1 );
/*============================================================================== User-defined Functions ==============================================================================*/ function EMA0(A, p) { r[0] = a[0]; ep = 2/(p+1); for(i = 1; i < BarCount; i++) { r = r[i-1] + (a - r[i-1]) * ep; } return r; }
function OptimizeNot(a1, a2, a3, a4, a5) { return a2; }
/*============================================================================== Entry and Exit Rules ==============================================================================*/ tr = Max(H-L, Max(abs(H-Ref(C, -1)), abs(Ref(C, -1)-L))); tr[0] = H[0] - L[0];
fast = EMA0(C, Optimize("FastEMA", 15, 20, 140, 5)); slow = EMA0(C, Optimize("SlowEMA", 150, 150, 1000, 10)); Buy = Cross(fast, slow); Sell = Cross(slow, fast); Buy[1] = 0; // to avoid false signal at the beginning //ApplyStop(stopTypeLoss, stopModePoint, ATR_multi*Ref(ATR0, -1), True, True );
/*============================================================================== Skid of Executions ==============================================================================*/ BuyPrice = (H+O)/2; SellPrice = (L+O)/2;
/*============================================================================== Position Sizing ==============================================================================*/ ATR_multi = OptimizeNot("ATP Multi", 5, 1, 9, 1); ATR0 = EMA0(tr, 20);
Risk_Per_Share = Ref(ATR0, -1) * ATR_multi; Heat = OptimizeNot("Heat", 0.10, 0.01, 0.50, 0.01);
PosSizeFactor = Heat / Risk_Per_Share; // the real position size value is calculated within CBT SetPositionSize(PosSizeFactor, spsValue);
/*============================================================================== Automatic Analysis Action Options ==============================================================================*/ AAAction = Status("action"); if(AAAction == actionIndicator) { Plot(fast, "FastEMA", colorRed); Plot(slow, "SlowEMA", colorYellow); } else if(AAAction == actionExplore) { Filter = 1; AddColumn( DateTime(), "Date", formatDateTime ); //AddColumn(DayOfWeek(), "DayOfWeek", 1); AddColumn(O, "Open"); AddColumn(H, "High"); AddColumn(L, "Low"); AddColumn(C, "Close"); //AddColumn(Avg, "AVG"); AddColumn(fast, "FastEMA", 1.3); AddColumn(slow, "SlowEMA", 1.3); AddColumn(ATR0, "ATR", 1.3); //AddColumn(Risk_Per_Share, "Risk/Share"); AddColumn(IIf(Buy, 111, IIf(Sell, 222, 0)) , "Buy1Sell2", 1); AddColumn(PosSize, "PosSize%Eq"); AddColumn(Equity() , "Equity"); } else if(AAAction == actionPortfolio) { bo = GetBacktesterObject(); bo.PreProcess(); // Initialize backtester for( bar=0; bar < BarCount; bar++) { eq = bo.Equity; for ( sig=bo.GetFirstSignal(bar); sig; sig=bo.GetNextSignal(bar) ) { if (sig.isExit()) { if(bo.ExitTrade(bar,sig.symbol,sig.Price)) { _TRACE("EXIT: " + sig.symbol + "@" + sig.Price); } } }
// update stats after closing trades bo.UpdateStats(bar, 1 ); for ( sig=bo.GetFirstSignal(bar); sig; sig=bo.GetNextSignal(bar)) { if (sig.isEntry()) { // sig.PosSize is passed from Phase I. ps = Round(( eq * sig.PosSize)/250)*250 * sig.Price;
