How to avoid crossed orders

[brima]

Today I started live trading and obviously orders got crossed.

I tried to sell 1 fdax in order to close a position and exactly at the same second my strategy wanted to go short with a sell short order and due to overmargining an error was triggered and my strategy stopped :-((

Can this situation be avoided by using the command:

if (position.MarketPosition == MarketPosition.Flat)
{
<new entry>
}
...

thanks

Yes, that would work.

And when exactly is the condition
(position.MarketPosition == MarketPosition.Flat) true?

as soon as the flattening order is
a) PendingSubmitt
b) Accepted
c) Working
d) Filled

[NinjaTrader_Ray]

As soon as the position is flat determined by incoming executions.

Does that mean as soon as an flattening order has category "Execution" in the log file?

An order can be made up of multiple executions, but in concept your understanding is correct.

@mrlogik

unfortunately I'm not working with the advanced order handling yet, my code is as follows:

protected override void Initialize()
{
SetStopLoss(CalculationMode.Ticks, stoplossticks);
CalculateOnBarClose = false;
}

protected override void OnBarUpdate()
{
#region ENTRY
if ( (<EntryCondition == true>) & (Position.MarketPosition == MarketPosition.Flat))

{
EnterShort(1)
or
EnterLong(1)
}
#endregion

#region EXIT
if ( (<ExitCondition == true>) & (Position.MarketPosition != MarketPosition.Flat))
{
ExitShort(1)
or
ExitLong(1)
}
#endregion
}

Hopefully that makes sense and works fine now.
