Yes
So the value of Buffer1[i] is returned to double buffer1 and then setindexbuffer uses the value from double buffer1 to draw the line???

Yes, however, think of the double array named buffer1 as a bunch of individual double type variables. each one of the elements in this array hold a indipendent value.

it looks like this,

Buffer1[0=i+0] buffer1[1=i+1] and so on until the array is filled with the moving average values for each bar.

Then the SetIndexBuffer(0, buffer1) command connects the entire array named buffer1 to the reserved chart Index 0. Then the SetIndexStyle(0,DRAW_LINE,0,0,Red) take each value that is stored in each element of the array named buffer1 that has been connected to the index 0 and plots that value on the chart

Jubii. I now finally understand it

But I still dont understand what comes before that. I don't know why but I can't concentrate right now.

int limit;
Here we define the variable limit

int counted_bars=IndicatorCounted();
last counted bar will be recounted. Does this happen at the first tick of a new bar?

if(counted_bars>0) counted_bars--;
If counted_bars is greater than 0 then we substract 1 from counted_bars.
Why? Am I right if I say that counted_bars is always 0 or 1. (The note before says (last counted bar will be recounted) that's why I say either 0 or 1.

limit=Bars-counted_bars;
limit=Bars-counted_bars; Here the variable limit is created.

I will answer these questions then I am going out to dinner with my wife and will look at this thread later.

The first statement is yes

The second statement is correct I assume. I am not too concerned what the actual value of counted_bars is, as long as it is assigned correctly for the chart and it is indeed that.

The third statement is correct, but lets get the nomenclature right. limit was created when we defined it as a int in the first statement. Now limit is receiving the value of the equation bars - counted_bars

Here I try to explain the whole function

int limit;
We creates the variable limit
int counted_bars=IndicatorCounted();
Returns counted bars minus 1
if(counted_bars>0) counted_bars--;
Here the last bar is being recalculated. I don't know how it works.
limit=Bars-counted_bars;
The limit variable has the value of all the bars on the chart minus counted bars.
for(int i=0; i<limit; i++)
The function below will be executed until limit is not greater than i anymore. If limit is 20 then the function below will be executed 20 times.
{
Buffer1[i] = iMA(Symbol(),0, MAPeriod, 0, MAType, PRICE_MEDIAN, i);

}
Inside the brackets is the function. Functions are allways inside brackets.

iMA calculates the moving average and returns its value to buffer1[i] and double buffer[1] gets the array from buffer1[i]. setindexbuffer and setindexstyle gets the array from double buffer1 and uses it to draw the line on the chart.

symbol means the symbol that is used. How do I define the symbol to be used. I tried to write EURUSD inside like this symbol (EURUSD) but that didn't work.

0 is for the timeframe. 0 means the current chart timeframe.

MAPeriod has the value of the extern variable MAPeriod.

the next 0 is for the shift.

ma_method has the value of the extern variable MAType which can be 0, 1, 2 or 3.

Applied price is PRICE_MEDIAN.

and the shift is i

Hi, I just got home.

I am going to sleep now, but you are on the right track, you just did not assign the buffer2 to a new index. remember you have indexes 0 thru 7 so 0 has been taken with buffer1 what would be the next one to use?

  • Nov 30, 2008 1:36am Nov 30, 2008 1:36am
Also you need the first one we did in the for loop as well, so you would have buffer1[i] = iMa...
buffer2[i] = iMa...

in the for loop

Yes. Finally it is all working. Thank you for all the help. I think I have learned more from you than I could from any tutorial.

I can see that I have deleted the first Buffer1[i]. I thought it was still there. The answer to your question is 1 because it starts at 0.

I am starting to like mql more and more

Because I had defined the account number it should work for.

How do I say or if isdemo() in the following code.

if(AccountNumber()==accnumber)

I have tried if(AccountNumber()==accnumber) ||isdeomo() but I got compilation errors.

If ( isdemo()== false ) return(0);

This will stop the program if it is not a demo account it should be the first line of code in the start ()
Place the curser on isdemo() and press F1

This should be
if ( AccountNumber() == accnumber || isdemo() ) do something;

What I want to do tomorrow is take the 2 moving average indicator we wrote here and make a simple EA using the iCustom() Then we will make the same EA using iMA() instead. I want to show you how you can draw logic from your indicator you wrote to be used directly in your EA. so what you see on the indicator will be executed in the EA exactly.

It is 1:15 in the morning here, so I am going to sleep now . see you tomorrow. Practice doing different things. Try changing the property to a separate window and make a iRSI() indicator. See how that goes.

so you change the window to a separate window. Interesting and it shows you are getting this. good night for now.

Could you do me a favor and delete your chart and then use the go advanced and use the manage attachments and then just upload the chart. it will keep the thread neat and not oversized... thanks

I just removed it. It was just so you could see how it looks like in my computer. Good night.
