It's not impossible, but I have to create a block for it 
Otherwise as a function it's something like this:
ObjectCreate("Name", OBJ_TREND, 0, Time[10], Bid, Time[0], Bid);
ObjectSet("Name",OBJPROP_RAY,0);
Where Time[10] is the time value for 10th candle in history, and the second row tells that the trenline has beginning and end (otherwise it goes to infinity)
Ummm... you have 3 blocks, two of them are connected and one of them is not. In fxDreema not-connected blocks are not included to the final file. Just connect it like other two are connected - drag orange circle to white circle.
Nice. And this happens when the same variable name is defined in Variables and Formula block. It will be fixed.
Levels tester is only to check what is going on, normally it should be on top level (to show you everything), but in this case it can be used this way.
Block 2 looks disconnected to me, it will not be added to the final project.
I don't know, I never tested with so much candles, so if you do it - check twice if all values are ok before using them.
Thanks! I fixed that for the web version, it will be ok for the next local build. The problem comes from that non-numeric ID of block "No123", but I have to rewrite the whole copy/paste system, so there will be more changes to this (which I hope no one will notice). You also have 1 extra month... bonus
Something special with those 5 blocks in "on Tick" that is specific only for them - the same symbol in their names, id numbers?
If you can send me copy of project like this where this can happen, it will be the best.
Start candle should be the one with lowest ID. Better select specific timeframe. Adjust is fine, it should work, but candles to be used are so many, so check for error messages eventually.
Check "Levels tester" block, it's near the top
And I think it's working already. If not, try to reload the page.
Yeah, it looks like something is not ok, I will check that immediately. Thanks for reporting that!
If this is a new block that can work, then it looks that it is copied with connections - this block is connected to blocks in different section, which normally is not allowed, but is possible. I still can't replicate it (actually other bugs happens to me), maybe there is something specific in your project that causes the problem or some specific step-by-step actions, but I think if you detach it, it will work (right-click - Detach).
Whooo, 5-years, here I smell history data issues. In my backtester the biggest TF is Daily, on live it is Monthly, but knowing the numbers of candles to use... check in Condition, somewhere in "Market properties" for highest/lowest price for candles period (also choose timeframe there). You can also create a custom block for these calculations, otherwise Formula blocks should be used. And use calculations in "on Init" if there is no need to reaclculate often. But if you know the actual highest/lowest prices and you can write them manually, I recommend to use them directly. 5 years is so big period, that somehow does not deserve calculations. And once when you reach price over/below the limits, then you work on lowest scale, but of course this depends on the strategy.
In case you are interested in coding, here are the functions that currently calculate highest, lowest prices:

well, they are a little bit complicated, but if you understand coding a little, you can perhaps get the idea
It works as expected on my platform, but if you have some way to show me the problem, I will check it
Unfortunately I don't have working Renko bars here, this was always a bit confusing for me, but as I remember offline chart is used. Can you confirm that the EA is working at all on these charts? Once I added options to work with offline charts (Options->Project Options), but I have to refresh my mind about how this worked... Now, is the EA working actually?
There are different ways to do that. The simplest is to use the block "Buy now (Custom Martingale)" and/or "Sell now (Custom Martingale". These blocks handle Martingale by themselves. In future I think I will remove the whole betting category and I will add these money managements in "Buy now" and "Sell now" as options.
And the other way is making it more open and detailed (using more blocks and variables). Today I helped someone else with this example: http://fxdreema.com/shared/f9fYbbupc
I can suggest to give these blocks name that is text, not numeric ID. Yes, it's possible for block ID to be some text, and this text will not be changed after normalize. And it will be more meaningful, but use IDs without spaces and special symbols - only latin letters and 0-9.

I hope it will work. Thanks for reporting that!
NormalizeDouble() problem 
Fixed, and thanks for the report!
I modified the project a bit, check this one: http://fxdreema.com/shared/7uiuj8mZ
