dear mike,
i understood where you want me to direct. for you reference i am giving full afl for my system which works fine giving me two extra coloms of initial risk & expectancy/trade coloumwise. but when i try to change risk perameter as shown in following afl i get blnak colom of initial risk & expectancy/trade. so i wnt to know how to get initial risk coloum when using risk = enty - stop value.
afl.
Capital = 100000;
SetOption("InitialEquity", Capital );
RoundLotSize = 1;
possize = 0.8*Capital;
allocationrisk = 0.8; // max capital employed per trade
risk = 0.05*Capital; // % max risk per trade
/* calling custom backtest*/
SetCustomBacktestProc("");
if( Status("action") == actionPortfolio )
{
bo = GetBacktesterObject();
bo.backtest(1);
Sumprofitperrisk = 0;
numtrades = 0;
// iterate for closed trades
for( trade = bo.getfirsttrade(); trade; trade = bo.getnexttrade() )
{
rmultiple = trade.getprofit()/risk;
trade.addcustommetric("initial risk $" , risk );
trade.addcustommetric("R-multiple" , rmultiple );
Sumprofitperrisk = Sumprofitperrisk + rmultiple ;
numtrades++;
}
expectancy3 = Sumprofitperrisk / numtrades ;
bo.addcustommetric( "Expectancy (per risk)", expectancy3 );
bo.listtrades();
}
xb = IIf(C > EMA(C,7),20,0);
xs = IIf(C < EMA(C,7),-20,0);
y = TimeFrameGetPrice("h",inMonthly,-1);
z = TimeFrameGetPrice("h",inMonthly,-2);
p = TimeFrameGetPrice("l",inMonthly,-1);
q = TimeFrameGetPrice("l",inMonthly,-2);
r = TimeFrameGetPrice("h",inMonthly);
s = TimeFrameGetPrice("l",inMonthly);
wz = Max(y,z);
zb = IIf(r > wz ,30,0);
wq = Min(p,q);
zs = IIf(s < wq,-30,0);
yw = TimeFrameGetPrice("h",inWeekly,-1);
zw = TimeFrameGetPrice("h",inWeekly,-2);
pw = TimeFrameGetPrice("l",inWeekly,-1);
qw = TimeFrameGetPrice("l",inWeekly,-2);
rw = TimeFrameGetPrice("h",inWeekly);
sw = TimeFrameGetPrice("l",inWeekly);
wzs = Max(yw,zw);
yb = IIf(rw > wzs ,25,0);
wqs = Min(pw,qw);
ys = IIf(sw < wqs,-25,0);
score = xb+yb+zb+xs+ys+zs;
avrage = MA(V,30);
diffvol = (V-avrage)/avrage;
Buy = C > Ref(HHV(H,2),-1) AND C>O AND score > 70 ;
BuyPrice = C;
bstopamount = BuyPrice-(wqs - 1);
Sell = L < wqs;
SellPrice = wqs - 1;
ExRem(Buy,Sell);
Short = C < Ref(LLV(L,2),-1) AND C<O AND score < -70 ;
ShortPrice = C ;
sstopamount = (wzs +1) - ShortPrice;
Cover = rw > wzs ;
CoverPrice = wzs + 1;
SetPositionSize( 100, spsShares ) ;
ExRem(Short,Cover);
//PositionSize =IIf(Buy, Min((risk/bstopamount)*BuyPrice,possize),Min((risk/sstopamount)*ShortPrice,possize));
//PositionScore = PositionSize ; //(V- MA(V,7))/MA(V,7) ; OR ma(v,5)/ma(v,20); prefer stocks that High vol thrust;
//ApplyStop(0,1,4,1);
thisk works fine.
but following chane gives blank coloum.
