Simple strategy

I am needing some help with getting an order to enter once a doublema changes from falling to rising.
I have tried several things, but can't get it to work at the correct spots.
I just need help with the entry trigger. When DoubleMA changes from falling to rising (it changes colour anyway) I would like to enter a long.
I would like to only take one trade per change from falling to rising as well.

As it is not crossing over anything, I am confused.
Thanks in advance
Regards

ok - lets see ....

first of all - i dont like these big indicator-codes like the DMA-stuff in strategys - thats why the first step would be to create a new small indicator or reducing it to an easy formular (without all color+parameter-things) wich hits what i needs -- example :

ZeroLagEMA(ZeroLagEMA(period), period)

than as condition a would try this :

if
ZeroLagEMA(ZeroLagEMA(period), period) [0] > ZeroLagEMA(ZeroLagEMA(period), period) [1]

... do something

if
ZeroLagEMA(ZeroLagEMA(16), 16) [0] > ZeroLagEMA(ZeroLagEMA(16), 16) [1]

... ENTER long ...

If this easy thing does what you want, you can go on + add more conditions
thats my why of building up + testing conditions.

OK. Thanks. Will give it a go

also - depending on the instrument - i sometimes use to make a rounding of the indicator-values i compare to eachother in my conditions.

Mike,
I am wondering how I can use this information in a strategy please.
I am a real novice when it comes to C#.
"I released a newer version of DoubleMA with more moving averages and a Signal dataseries (0 neutral, -1 short, 1 long).
Could you please provide an example?
ie: if
(DoubleMA(45,NinjaTrader.Indicator.DoubleMA_internal.DMAType.EMA,45,NinjaTrader.Indicator.DoubleMA_internal.DMAType.EMA).signal[1]

Enter long?

This looks right, I am not sure I understand what is not working for you.

Signal dataseries:
1 == rising
0 == neutral
-1 == falling

Keep in mind if you use the wizard it places + sign instead of . in a couple of places, you need to manually change it, but your string above seems fine.

Thanks Mike.
I tried it and it ame me an error of:Cannot implicitly convert type 'double' to 'bool'
So I tried this:
if (DoubleMA(30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA,30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA).Signal[1] > DoubleMA(30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA,30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA).Signal[-1])
{
EnterLongLimit(DefaultQuantity, GetCurrentAsk(), "Long");
}
It compiled but doesn't work.
All I am trying to do it enter a long after the DMA goes from falling to rising. I must be dumb.
Sorry

Ok, here is the issue

Signal[x] where x=number of bars ago. 0 means current bar that just closed, 10 means 10 bars ago, 100 means 100 bars ago. That is basic NT.

What you need to do is change the end of your string to:

Signal[0] == -1) (this represents a short, for a long change to Signal[0] == 1)

Thank you. Sorry for hassle. At least I am giving it a go.
I have a lot to learn.

No hassle at all. I had some "duh" moments when I learned it as well.

I get a lot of trades though. I was hoping for one trade each time the DMA changes from falling to rising.
Here is a screen shot. 2009-07-22_1919

Is because you are only asking if it is Signal[0] == 1. That means if long.

What you need to do is add a second if statement that checks the prior bar, such as Signal[1] != 1.

This means if bar 1 is not equal to 1, and bar 0 is equal to 1, then that means it changed and go long.

Code

if (DoubleMA(30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA,30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA).Signal[0] == 1)

if (DoubleMA(30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA,30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA).Signal[1] != 1)

{
                EnterLongLimit(DefaultQuantity, GetCurrentAsk(), "Long");
            }

It seems to be not lining up with the DMA. Is that because the DMA paints back 2 bars?

There is a whole thread about DMA and signal issues. (I think this is it, not sure). I personally don't use it so can't comment. You might try using the DMV dataseries and see if it works any better for you. DMV returns the value not a signal, so you need to use Rising or Falling:

Code

if (Rising(DoubleMA(30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA,30,NinjaTrader.Indicator.DoubleMA_internal.DMAType.ZeroLagEMA).DMV))

Also as mentioned earlier by max-td here you might eliminate DoubleMA and do it his way. Although honestly, I've not tested this and am not sure if it produces the same results as DoubleMA.

Ok. Thanks.

I fixed this post, I didn't realize some extra code was in there until now.

Vast, here is a basic strategy, made with the wizard in about 30 seconds, without using DoubleMA but only ZeroLagEMA.
Maybe it can help.

Thanks Sam.
I guess I was hoping that I could build a strategy on the DMA and other indicators. I had hoped to use the change of colour as a reference point. ie. When the DMA turns from falling to rising is changes colour.
Anyway, it seems to be not possible. The entries are too slow.

Thanks BigMike
after 2 weeks HERE is the answer .... "Keep in mind if you use the wizard it places + sign instead of . in a couple of places, you need to manually change it, but your string above seems fine.

Mike "
i replaced the'+' with a '.' and now it will compile!!

Have a look at the Aardvark strategy that nano posted recently in the elite section .. lots of good code to help you out
