I'm afraid it is going a little too fast. I am nearly finished with understanding the moving average indicator. Here is what I have so far, with comments to everything.

#property indicator_buffers 1 // Here we define how many lines we need in the indicator.

extern int MAPeriod = 10; //Here we have defined an extern variable with the name MAPeriod and a default period of 10.
extern int MAType = 0; //...

Okay.

int counted_bars=IndicatorCounted();
Here we created a variable called counted_bars. The Indicator_Counted function returns the amount of bars not changed after the indicator had been launched last and it recounts the last bar.

if(counted_bars>0) counted_bars--;
Here we creates an if function. If counted_bars is less than 0 then ???

you are correct. the answer to then is Counted_bars gets increments one less. It would be like saying Counted_bars = Counted_bars - 1

However, please note that it is a greater than symbol not a less than symbol

How can it be greater than when we substract 1?

It can be greater than 0 not than itself. So, if it is greater than zero, we will take the value of Counted_bars, (what ever that may be) and subtract one from it.

This is useful when we set the limit number of bars in the next line. When you get there we will talk about that.

Okay.

limit=Bars-counted_bars;
Here we creates a local variable which is called limit and the variable gholds the value of counted_bars.

Put your curser on Bars and press F1 and see what it says about Bars

Bars = All the bars on the current chart. I will be back in about half an hour. I was just told it's dinner time now.

for(int i=0; i<limit; i++)
Here we make a for loop. We define the variable i and give it a value of 0. The loop ads 1 to i until i is not less than limit.

Buffer1[i]
Do we call buffer1 here and give it the value [i]????????? If we do that then why not just give it the value [i] to start with instead of waiting to now.

Yes to the first statement.

In the buffer1[i], we are assingning the value of the moving average i number of bars back to the same i element in the Buffer1 array. So, this has the effect of synchronizing the Buffer1 array with the Moving Average for each bar back in time to the limit amount that we established above.
So, the SetIndexBuffer and the SetIndexStyle can draw each elemement of the array Buffer1 on the chart at the correct bar it should be associated with.
We are not calling Buffer1[i] we are assigning Buffer1 element [i] to the...

So buffer1[i] is connected with double buffer1[] which is connected with property indicator_buffer 1????

Yes, because we delcare the array buffer1[]; in the global area, we can have access to it in any function and now we are actually assigning values to it, for the setIndexBuffer to connect to and then the setIndexStyle to draw a line with on the chart at the value that is in each element of the array buffer1 at the bar associated with each element in the past.

The question should have been if buffer1[i] is connected with setindexbuffer which is connected with double buffer1. Is that right?
