Add a channel to an existin indicator

With the existing indicator On Balance volume (mq4 and ex4 attached) i would like to add a channel of Moving averages applied to it. (SMA and EMA input).

The channel will be based as easy as follow, 3 moving averages,1 applied to high,1 to lows and 1 to close.

Metatrader for itself allows u to add 1 moving average to an indicator, but just 1, and u are not able to specify to the high or lows....

I would like to make 2 ways  of doing that. 

1) As i said,creating the moving average channel

2) Creating a moving average with ATR desviation (indicator mq4 attached also.)

The main reason why i said the 2 features is becuase i would like to test what will be better, and, maybe there is some code issues that we dont allow us to code what i have on my mind. Thats why i provide this 2 solutions.

Hope this will clarify the main idea. i have attached an EXAMPLE of how i would like to have that.

THanks
