testing is learning
try it with a custom function, if your problem about resizing persist, it is MT5 bug and only who can solve it is the metatrader company

yes send it, I hope it is not very complicated and big project 
Someone can play and convert it into blocks, other users can benefit from it 
to guide you what to do:
this is an example based on the steps + in addition it plots the lines (from which it gets the values, for you it is done with indicator, so change the functions accordingly)

this is only for drawing lines:



a tolerance should be added (to eliminate price fluctuations around the line, but this is the task where you can play :D)
...
by the way, the whole code can be converted into blocks, but it takes a longer clicking time and I don't have it ... moreover, in my past replies about working with loops is covered almost everything 
Actually, it seems be working right ...
when the input parameters are:
Then both, buy1 and buy2 are opened right, also BE for buy1 is working:

then, buy1 is closed because Onsatura is reached, and buy2 still waiting for own Onsatura level:

It is related to the logic used between blocks, respectively a mismatch between input parameters.
If the input parameter "Onsatura" is 50 (pips) and the input parameter named "MouaBE" is "0", then the stops are modified to the null and the trade is closed. Set the "MouaBE" to 100 or so and everything should working fine 

....
apply to your testing a "test buttons" for trades opening and it will give you the possibility for better testing:


I was not able to replicate your issue with these settings:

Standard function of the metatrader is used in the block:
https://docs.mql4.com/chart_operations/chartscreenshot
drawing such trendlines is possible with the help of regression channel, you must find the regression channel indicator (for MT4) which print the values into buffers (forget the ones that draw standard regression lines) ... if you dig the google very deeply, you will be able to find something (long time ago I found something, ... I don't know the exact name of indicator and I don't have that strategy saved, but I am 100% sure that I found and it worked in fxdreema) ...
Lots can be any, dynamic or calculated - it doesn't matter. What matters is the trade opened without stops.
How to open a trade with desired stops on the ECN account:
One of the ways to achieve it:

Unhelpful remark - I can't help that person otherwise than with my recommendation. The reality is that none of us knows how to write a manual about fxDreema for everyone. Admin doesn't know it, I don't know, nobody knows it. There were people who tried to make a paid fxdreema school or academy. I don't know if they still exist. My opinion (can be wrong) is that fxdreema is mostly used by a regular/standard people, not real investors (various reasons). These people don't have the money for real investments and thats why they tried luck with a big leverage. Manual trading went wrong and they asked EAs for help. Paying a programmer for "EA in head" resulted into large costs so they found the programming-less tools as a significantly cheaper alternative (otherwise the programmer would be cheaper, right?). Of course, the best is fxdreema. It helped to a lot of traders, but there are people who will be never satisfied.
Back to a documentation:
If you count it together and put it in a manual, how many pages it will have? Will it be useful at all? Probably not enough.
I did EAs with 1000 of blocks which are not profitable.
I did EAs with a few blocks which are profitable with their own risk

(not a holly-grail myths, this may be another book, at least as forexfactory was created and works)
So where to start with the expected manual? Following the most complicated EAs and showing how they fail? Or searching for a key in the simplicity, but learn about the potential of fxdreema nothing?
What type of manual?
Do you think your karma will improve if you predict and talk about the karma of others and you don't focus on your own?
I advise you:
Time is a problem, I am not often here ... besides, for 90% of questions it would be like ticketing system for the assembly of EAs or to teaching someone .
It wouldn't be like support for fxDreema tool at all (all questions about a classic use of fxdreema were answered in the forum)
.
.. these things of support will never be paid by the standard subscription ...
It is like photoshop, one can do an editing job for someone else, the person does not learn anything.
So I can do this paid assembling EAs support right now, I don't want to do it, because it would not be the way.
