EMA Cross Strategy

[philrx300]

I seem to get an error when I run a strategy and It buys let's say, 100 shares when the EMA's cross.
Then at a point (when the EMA's cross again) it should sell the 100 shares and short 100 shares.

That's where I get the error. It will close the first position and not open
the new one. See below code. Is this not correct? It works great in
back test mode, but for some reason I get errors when it is live and
the strategy stops.

// Condition set 1
if (CrossAbove(EMA(Fast), EMA(Slow), 1))
{
EnterLong(Shares, "EMA System Long");
PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\Alert4.wav");
}
else if (CrossBelow(EMA(Fast), EMA(Slow), 1))
{
EnterShort(Shares, "EMA System Short");
PlaySound(@"C:\Program Files\NinjaTrader
6.5\sounds\Alert4.wav");
}

Please be more specific as to what errors you are getting. Thank you.

Strategy ‘SRSSYSTEM’ submitted an order that generated the following error ‘OrderRejected’. Strategy has sent cancel requests, attempted to close the position and terminated itsef.

Live? Sim? What brokerage connection are you using?

[philrx300]

Live. TDAmeritrade.

For TDA, you may need to explicitly exit and then enter with ExitLong() and then EnterShort().

I was thinking that, but how do I handle if I don't have any shares... like for the first trade of the day? Can you help me? Would I just add ExitLong() before the EnterShort()?

Here's what I have now:

// Condition set 1
if (CrossAbove(EMA(Fast), EMA(Slow), 1))
{
ExitShort("Exit Short", "EMA System Short");
EnterLong(Shares, "EMA System Long");
PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\Alert4.wav");
}
else if (CrossBelow(EMA(Fast), EMA(Slow), 1))
{
ExitLong("Exit Long", "EMA System Long");
EnterShort(Shares, "EMA System Short");
PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\Alert4.wav");
}
}

An Exit order is ignored if no position is previously held. There should be no problems there.

I get an error on NINJA but it does execute. A pop up boxes pops up and I click everything is ok. Seems like the ExitLong() is messing things up if there is no position open.
