Thanks for your reply Tasker_182!

Yeah I have been working my way through the help file. It is a ton of information to wrap my head around but I am trying!

I have added print statements to my code so it looks like this:

 
Code
        {
            if (CrossAbove((GetCurrentAsk() + (Offset * TickSize)), SMA(SMAlookback), 1))
			{
				Print("LongCurrentAsk: "+GetCurrentAsk()+" (Offset+Tick): "+(Offset * TickSize)+" SMA: "+SMA(SMAlookback)[0]);
				Print("Calculated value: "+(GetCurrentAsk() + (Offset * TickSize)));
                EnterShort();
			}
            else if (CrossBelow((GetCurrentAsk() + (Offsetneg * TickSize)), SMA(SMAlookback), 1))
			{
				Print("ShortCurrentAsk: "+GetCurrentAsk()+" (Offsetneg+Tick): "+(Offsetneg * TickSize)+" SMA: "+SMA(SMAlookback)[0]);
				Print("Calculated value: "+(GetCurrentAsk() + (Offsetneg * TickSize)));
                EnterLong();
			}
        }
When I look at the output window as the code works I get this:

 
Code
ShortCurrentAsk: 92.94 (Offsetneg+Tick): -0.05 SMA: 92.8932
Calculated value: 92.89
2013-06-04 3:37:38 AM Entered internal PlaceOrder() method at 2013-06-04 3:37:38 AM: BarsInProgress=0 Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='' FromEntrySignal=''
ShortCurrentAsk: 92.94 (Offsetneg+Tick): -0.05 SMA: 92.8932
Calculated value: 92.89
2013-06-04 3:37:39 AM Entered internal PlaceOrder() method at 2013-06-04 3:37:39 AM: BarsInProgress=0 Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='' FromEntrySignal=''
2013-06-04 3:37:39 AM Ignored PlaceOrder() method at 2013-06-04 3:37:39 AM: Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='Buy' FromEntrySignal='' Reason='Exceeded entry signals limit based on EntryHandling and EntriesPerDirection properties'
ShortCurrentAsk: 92.94 (Offsetneg+Tick): -0.05 SMA: 92.8932
Calculated value: 92.89
2013-06-04 3:37:39 AM Entered internal PlaceOrder() method at 2013-06-04 3:37:39 AM: BarsInProgress=0 Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='' FromEntrySignal=''
2013-06-04 3:37:39 AM Ignored PlaceOrder() method at 2013-06-04 3:37:39 AM: Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='Buy' FromEntrySignal='' Reason='Exceeded entry signals limit based on EntryHandling and EntriesPerDirection properties'
ShortCurrentAsk: 92.94 (Offsetneg+Tick): -0.05 SMA: 92.8932
So in that instance the price was above the SMA, at 5 ticks above it went long(which is good!) the output window keeps coming up with this over and over again

 
Code
2013-06-04 3:37:39 AM Entered internal PlaceOrder() method at 2013-06-04 3:37:39 AM: BarsInProgress=0 Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='' FromEntrySignal=''
2013-06-04 3:37:39 AM Ignored PlaceOrder() method at 2013-06-04 3:37:39 AM: Action=Buy OrderType=Market Quantity=1 LimitPrice=0 StopPrice=0 SignalName='Buy' FromEntrySignal='' Reason='Exceeded entry signals limit based on EntryHandling and EntriesPerDirection properties'

Which would mean to me that it keeps getting an order spammed at it that it cannot fill. When in reality all I would like is for it to do nothing until the price moved to 5 ticks below the moving average and have it reverse and go short then.

So basically right now it will do the first entry correctly but it will not reverse for me! :/

Anyways I will keep at it. seems like its a fairly decent sized learning curve but hopefully worth it once I figure it out!

Reason='Exceeded entry signals limit based on EntryHandling and EntriesPerDirection properties'


Check what are the values for these properties of your strategy in the property grid.

You can change these values in your code as well (in Initialize() ):

 
Code
EntriesPerDirection = 1;
EntryHandling = EntryHandling.AllEntries;

I havent changed the entries per direction from the default setting which from the webinars I have seen I believe the default value is 1.

I didn't want to change that because at this time I only want can do the one contract at a time! :P

So because I never played with that variable I do not even see it at all in the initialized() area

Avoid CrossAbove() and CrossBelow()

First of all, you are using CrossAbove() and CrossBelow() incorrectly. If you look at CrossAbove() for example...

CrossAbove()

You will see that the first parameter needs to be a DataSeries object, not a double. The expression

 
Code
GetCurrentAsk() + (Offset * TickSize)
evaluates to a double, not a DataSeries. I'm surprised your code even compiles! NT's syntactical leniency is the cause of your headaches.

Personally, I've had problems getting these cross methods to work for me sometimes, maybe I was using them incorrectly, but a long time ago I decided to never use them. Now I do something like "if x > y and x wasn't > y in the last bar" logic to determine crosses above.

So if I was to use the Close instead of the ask (not sure why you're using the asking price) it could be

 
Code
SMA sma = SMA(Lookback);
double smaNow = sma[0];
double smaLastBar = sma[1];
double priceNow = Close[0];
double priceLastBar = Close[1];

if (priceNow + (Offset * TickSize) > smaNow && priceLastBar + (Offset * TickSize) <= smaLastBar)
...then we have a cross above scenario
