Help needed to convert my system to Nt7...!

Let me ask you.....

Can you replicate everything you need on the chart with everything in NT7? By that I mean, if you had to place all the indicators on the chart you need, would you have all of them?

One thing, working on the oscillator now, and it references an 'AMA', which is amibroker's 'AdaptiveMovingAverage.'

In NT7, there is a MAMA which is the Mesa-AdaptiveMovingAverage. It's probably not exactly the same as the one used in AmiBroker as part of the calculations for your oscillator. So I want to use something similar to what is being used for that calculation in Amibroker.

Can you add say the AMA from amibroker to a 5 minute TF chart, and post back here a picture of it so I can see what it looks like and see if we can use this MESA that comes with NT7. If not we'll have to find an alternative.

Here is an Adaptive MA, originally for 6.5, may need minor changes for 7.

Here is another one.

You'll need to get the source from the Amibroker one to compare.

Thanks @Big Mike.

I was looking into that yesterday, i.e. the SCRIPT from ami. I was contemplating just adding it to the script for Linkon7s oscillator since it was pretty simple, but figured I'd wait till he showed up again.

I am not a coder, so most of my work is just self taught coding that is mostly a cut-paste job. That oscilator is not all that important now, as i have seen adaptive CCI work very well on nt7 and that will serve the same purpose.

Code

Plot(C,"close",colorGrey40,styleBar);

fast = 2/(2+1);
slow = 2/(30+1);
dir=abs(Close-Ref(Close,-10));
vol=Sum(abs(Close-Ref(Close,-1)),10);
ER=dir/vol;
sc =( ER*(fast-slow)+slow)^2; 

Plot(AMA( Close, sc ),"AMA",colorRed,styleThick);

this code will plot a chart that looks like this...

output = AMA( input, factor )

is equivalent to the following looping code:

for( i = 1; i < BarCount; i++ )
{
output[ i ] = factor[ i ] * input[ i ] + ( 1 - factor[ i ] ) * output[ i - 1 ];
}

I hope this helps a bit. And again, thanks for ur effort...!

Still haven't forgotten about this. Just haven't been around much on the weekedays.

@Big Mike....

In the following AmiBroker code:

Quoting

fast = 2/(2+1);
slow = 2/(30+1);
dir=abs(Close-Ref(Close,-10));
vol=Sum(abs(Close-Ref(Close,-1)),10);
ER=dir/vol;
sc =( ER*(fast-slow)+slow)^2;

Plot(AMA( Close, sc ),"AMA",colorRed,styleThick);

In the 3rd and 4th line, there is a reference to the absolute value and the sum. And this question is just about the language, do you know what the 'Ref' in ami-broker is used for?

Like if you converted those 3rd and 4th lines into plain English, what is it saying?

Is the 3rd line saying, "Assign to 'dir', the absolute value of the Current Closing bar's price MINUS the closing price 10 bars ago?"

Just used to reference an array, in this case the Closing price of x bars.

AmiBroker Formula Language Function Reference

@Big Mike
Just a point of clarity.....

So the ref function in ami, says that "ref(CLOSE, -10) returns the closing price 10 periods ago. In NT7 this would just be:

Code

Close[10]

Then they say that the 10-day rate-of-change is "CLOSE - ref(CLOSE, -10)" In NT7 this would be:

Code

Close[0] - Close[10]

Sounds right. I don't use Amibroker, so not 100%.

dir=abs(Close-Ref(Close,-10));

dir = absolute value of ( close - value of close 10 bars ago)

vol=Sum(abs(Close-Ref(Close,-1)),10);

vol = sum of last 10 bars of data of dir, means we add the last 10 value of dir

i hope it helps...!
