Channel codes

Make me a set of codes  , which can be included in existing indicator.source codes required.

The purpose of the code is to get a reading on indicator , if there is an up channel or a down channel.CHANNEL LINES ARE NOT REQUIRED TO BE DRAWN ON CHART , only a value input  of 40 points for up channel  or -40 points for down channel , if no channel exists indicator value is zero .This reading is required for my ea.

Write me a code  or a set of codes in the enclosed format to define a channel ,I need codes for indicator to add to logic .  

The code should be the same for each channel i.e 48 hour , 30 minute and 15 minute  , except time frames are different 

Define  three channels 1)  a last 48 hours(4 hour channel)   2)   last 2 hours  (15 minute channel)   3) and a 30 minute channel

channel should use using last two  tops on down resistance line and last two bottoms in up support line

usually codes are last low (4hour ,30 min and 15 min  and daily)  for bottoms of channels and last tops for down channels  (4hour ,30 min and 15 min  and daily) , if latest bottoms are higher ,it is a up channel  , if latest tops are lower it is down channel

also require lowest points of last 48 hours , 4 hours and 24 hours and highest points

Give me codes , I just paste in my indicator or Decision on this job will be made in 7 days. .Looking for c++ candidate will be given existing indicator format  template to input code.
