["lesslimbs" <lesslimbs@xxxxxxxxxxxx>]

Thanks for your help!!

i also posted on another board and got a similar reply. you can see 
below:

s=&threadid=101655&perpage=6&pagenumber=2

but it seems i cannot simply insert the cancel-code into the rest of 
the program to make it work, still lack cancel codes. 


//SETTING
A1 = 50;
B1 = 50;
C1 = 50;
D1 = 50;

//param trigger button to reset status
resetStatus = ParamTrigger("resetStatus","resetStatus");

//START
DateNumNow = Now(3);
DN = DateNum();
TN = TimeNum();

//check if order placed
OrderPlaced = StaticVarGet("OrderPlaced");

if(resetStatus)
{
StaticVarSet("OrderPlaced",0);
}

OrderPlaced = StaticVarGet("OrderPlaced");




//check if order is triggered, place order if condition fullfiled
if( (IsEmpty(OrderPlaced) OR OrderPlaced==0) )
{


ibc = GetTradingInterface("IB");
IBcStatus = ibc.IsConnected(); 

if( IBcStatus )
{
//Long side, place order

StaticVarSet("OrderPlaced",1);

LimitBuy = D1+A1;
parentIDLong = ibc.PlaceOrder(Name(), "BUY", 1, "LMT", LimitBuy, 
0, "DAY", False );
ibc.PlaceOrder(Name(), "SELL", 1, "LMT", LimitBuy+B1, 0, "DAY", 
False, 1, "", parentIDLong );
ibc.PlaceOrder(Name(), "SELL", 1, "TRAIL", C1, C1, "DAY", True, 
1, "", parentIDLong );

//short side, place order

LimitSell = D1+B1;
parentIDShort = ibc.PlaceOrder(Name(), "SELL", 1, "LMT", LimitSell, 
0, "DAY", False );
ibc.PlaceOrder(Name(), "BUY", 1, "LMT", LimitSell-D1, 0, "DAY", 
False, 1, "", parentIDShort );
ibc.PlaceOrder(Name(), "BUY", 1, "TRAIL", C1, C1, "DAY", True, 1, "", 
parentIDShort );

}
}
