Hello friends,
I am a newbie in Amibroker. Presently, I am trying to develop an intraday trading system for futures (15% margin). Based on EMA crossover it will buy and scale out the trade when in 0.5% profit (50%) and 1% (full exit). Trailing stop loss is 0.5%. The code is given below. Original code I got from the web, which I adapted for my use.
SetOption("InitialEquity", 100000);
//SetOption("MinShares", 100);
//SetOption("NoDefaultColumns", True );
//SetOption("AllowSameBarExit", True );
//SetOption("ActivateStopsImmediately" , True );
SetOption("FuturesMode", True );
SetOption("InterestRate", 0);
SetOption("CommissionMode", 1); //$$ per trade
SetOption("CommissionAmount", 0.031); // commission is accounted for in skid
SetOption("MarginRequirement", 15);
SetTradeDelays(0,0,0,0);
RoundLotSize = 50;
TickSize = 0.05;
timestore = TimeNum();
Buy = TimeNum() <= 150000 AND Cross( EMA( C, 4 ), EMA( C, 32 ) );
Sell = 0;
FirstProfitTarget = 0.5; // profit
SecondProfitTarget = 1.0; // in percent
TrailingStop = 0.5; // also in percent
priceatbuy=0;
highsincebuy = 0;
exit = 0;
for( i = 0; i < BarCount; i++ )
{
SellPrice[i]=0;
if( priceatbuy == 0 AND Buy[i] ) {
priceatbuy = BuyPrice[i];
}
if( priceatbuy > 0 ) {
highsincebuy = Max( High[i], highsincebuy );
if( exit == 0 AND High[i] >= ( 1 + FirstProfitTarget * 0.01 ) * priceatbuy ) {
// first profit target hit - scale-out
exit = 1;
Buy[i] = sigScaleOut;
BuyPrice[i] = Max( Open[i], ( 1 + FirstProfitTarget * 0.01 ) * priceatbuy );
}
else { // Added ELSE here for Initial entry trail stop
if( exit == 0 AND ( timestore[i] > 152000 OR Low[ i ] <= ( 1 - TrailingStop * 0.01 ) * highsincebuy ) ) {
// trailing stop hit - exit
exit = 3;
SellPrice[ i ] = Min( Open[ i ], ( 1 - TrailingStop * 0.01 ) * highsincebuy );
}
}
if( exit == 1 AND High[i] >= ( 1 + SecondProfitTarget * 0.01 ) * priceatbuy ) {
// second profit target hit - exit
exit = 2;
SellPrice[i] = Max( Open[i], ( 1 + SecondProfitTarget * 0.01 ) * priceatbuy );
}
else { // Added ELSE here for trail stop on scale out parcel
if(exit == 1 AND ( timestore[i] > 152000 OR Low[ i ] <= ( 1 - TrailingStop * 0.01 ) * highsincebuy ) ) {
exit = 3;
SellPrice[ i ] = Min( Open[ i ], ( 1 - TrailingStop * 0.01 ) * highsincebuy );
}
}
if( exit >= 2 ) {
Buy[i] = 0;
Sell[i] = exit + 1; // mark appropriate exit code
exit = 0;
priceatbuy = 0; // reset price
highsincebuy = 0;
}
}
}
PlotShapes( Buy * shapeUpArrow + Sell * shapeDownArrow , IIf( Buy, colorGreen, colorRed ), 0, IIf( Buy, Low, High ));
//SetPositionSize( 50, spsPercentOfEquity) ; // 2% of equity
SetPositionSize( 50, spsPercentOfPosition * ( Buy == sigScaleOut ) );
Unfortunately, I am not able to solve the sigscaleout portion of the code. Whenever, scale out is taking place the cash is becoming negative and afterwards no trade is taking place due to this.
The detailed log in AA is pasted here:
