Re write action script for entry signal lines for trend line trader MT4 expert

MT4
  Re-write  script part of  existing programs  version's 1.7  & 1.8  as provided in attachments
 for  trend line trader  Expert Adviser program.
The program was written when windows 7 was the standard.
 In the past year the signal part of the program which is designed to open a new position when the chart price bar
crosses the buy line ( green)  or sell line ( red)  which I manually draw on the price chart,RSI or  Renko offline chart.

In future assumed chart move direction or over last current price bar being made.

   
  See attached screen shots.
The issue may be caused by some minor program / script variations in latest version  of MT4
 The program has become inconsistent and un reliable at recognising when the Buy or sell line is crossed by the price bar.
 
  both on the MT4 time price chart  and
on Renko offline  timeless charts.

 Therefore I think that just the entry signal  section of the expert needs re scripting or  Re-write code
for activating order when manually placed signal line is crossed

--------

The other parts
of the Expert all still work fine. Placing stops & targets, moving stop to break even
and moving trailing stops. 
There are two versions of this expert  for which one rewrite should suit both -
you will be required to amend both. 

Thanks.
