Amibroker and Interactive Brokers (TWS) auto trading

I have a simple trading system. Want to develop a auto trading code from Amibroker to TWS (Traders Workstation). The code I have is not working or placing several buy and sell signal.

Description of the trading system:
When 2 period EMA (Exponential Moving Average) crosses above 5 period EMA buy.
When 2 period EMA crosses below 5 period EMA sell.
Period: 30 minutes
Trade US equities (Example: Apple stock).

What I need:
The chart should trigger buy and sell and execute the trade in TWS

AFL Code:
Buy = Cross( EMA(C, 2), EMA(C,5) );
Sell = Cross( EMA(C,5), EMA(C, 2) );

//BuyPrice = Open;
//SellPrice = Open;
Short = Sell;
//ShortPrice = Open;
Cover = Buy;
//CoverPrice = Open;

// trade on next bar open
SetTradeDelays( 1, 1, 1, 1 );
BuyPrice = SellPrice = Close;

// trade size: 25% of current portfolio equity
//SetPositionSize( 25, spsPercentOfEquity );


SetTradeDelays(1,1,1,1);


if ( LastValue( Buy ) )
{
ibc = GetTradingInterface("IB");

// check if we are connected OK
if( ibc.IsConnected() )
{
// check if we do not have already open position on this stock
if( ibc.GetPositionSize( Name() ) == 0)
{
// transmit order
ibc.PlaceOrder( Name(), "Buy", 1, "MKT", 0, 0, "Day", False );
}

}
}


if ( LastValue( Sell) )
{
ibc = GetTradingInterface("IB");

// check if we are connected OK
if( ibc.IsConnected() )
{
// check if we do not have already open position on this stock
if( ibc.GetPositionSize( Name() ) == 0)
{
// transmit order
ibc.PlaceOrder( Name(), "Sell", 1, "MKT", 0, 0, "Day", False );
}

}
}

Any help would be appreciated.

 

Go over to groups.yahoo.com and search for the Amibroker group. That's the best place to get help.

 

Thank you Steve!

 

I can recommend this API if you're after a quick fix: http://code.google.com/p/ib-csharp/

Its relatively stable and is maintained.

You just need to write the connection scripts to port your code over.

 

This will also give you what you want. I assume from your code your are trading of 30min bars?
