I have a question for programmers, how hard would it be to write an indicator to alert me when price is approaching an EMA? Is it something that you need a programmer for or is it something that Id be able to get a book and pick up myself? Also if it would not be too hard what book is good?

Hello kodflakes,
If you only want one ema in relation to price, and are going to use an ma cross signal, change the 2nd ma value to a 1 period SMA, with value to where you want price.
For example, if you want to know when price rises to reach a downtrending EMA, and want to use a cross indicator.
The 1st ma will be the ema value.
The 2nd will be set to a 1-period SMA measuring the High. A 1 period SMA will provide you with actual price value without having to add price action code. When "price" reaches the trend EMA, the signal will trigger.
MA1period = 55; //your trend ma's number
MA1mode = 1; // Changing this to 1 will make it an EMA.
MA2period = 1; // This takes only the current bar.
MA2mode = 0; // Changing this to 0 will make it an SMA.
In an attempt to make this easier to understand for anyone wanting to call an MA, look at this:
MA1 = iMA(NULL,0,1,0,2,1);
This will create a 1 period SMA from the high. It is to show you can use almost only numbers if you choose.
This is the syntax:
MA1 = iMA(TimeFrame,Shift,Period,Mode,Price,Count);
You may also use no numbers. variables are what really makes a code "jump"
NULL is the current TimeFrame.
0 is the Shift, in this case none.
Period for our moving average is set to 1, the current bar.
Mode is set to 0, for an SMA. 1 = EMA.
Price is what the average is based on. 2 = High. 0 = Close.
Count is the timer, normally leave this alone if you are learning from a code, but it can be set as a number. I have set it to 1, for the current bar.
If you're going to use an ma instead of true price, an SMA will provide with less lag, where an EMA may give more. This is not necessarily true for a 1 period, however it looks better practice
Look into the MetaEditor help file for more. CodersGuru created a tutorial that has helped many learn as well. Both are free and readily available
