Not possible yet, but I don't think you need it. If you can separate trades by type (buys and sells) it will be better. There is something weird on your side, I don't know what. It can be because you are using those checkboxes for input parameters. I downloaded your project and tried it on my side... all looks normal. So if you have TeamViewer I can check what is going on there.
Ummmm... can tou try with fresh download of 080? I updated it (quietly) yesterday few times and I think it should be fine now 
I think I fixed it already How is it now?
By the way "once per trade/order" are not needed at all.
If I use MA as an indicator (for the other group of blocks you have) I have this: http://prntscr.com/3ez8qs And I think it looks normal. No double trades anywhere. If you have double trades on live, search if you have another EA running in the same time.
Ummm... initial volume size is where the MM starts. For example Martingale, it can start from 0.1 and doubling. It depends on what MM you use.
Those warnings.... how is it now?
Opps, wrong command to the compiler. How is it now?
You used that "Program Files/MetaTrader" somewhere in the project? Give me some more details, what is on the picture is... I have no crystal ball Some .mq4 file?
И така става. Иначе е буквално "LasttradeProfit+LastHistoryProfit" в полето на Value -> Numeric
Променливите могат да се използват с имената си навсякъде, така че можеш да ги събереш дори направо в полето на Condition -> Value -> Numeric
Haha no, there is no block like "Fix my all problems now" 
I guess it's something in the logic. There is small chance that some block that is used is not working properly (as I found 4 blocks like this minutes ago). Or you are using blocks that you think they work in some way, but they work in another. In any case I can't tell what is the exact problem because I don't know how the project looks (you are using the local version as I can see).
The timeframe is not connected in any way with the trades and orders. Timeframe is only used for candles, indicators, stuff like that. What differentiates trades and orders is their Magic Number (well, also type ** and market [symbol]) and I can see you are using Group number, which is basically some form of Magic Number.
This project looks very good But I feel that you are trying to do something that can be done in simpler way... maybe. What is the overall idea for this MM?
Otherwise I can suggest to check those variables at some control points. Let's say "Print message" with content like this:
"Enter your text here" + VariableName
Damn, you are right, this block was faulty. I think I fixed it, how is it now?
I don't remember why I decided to add " = 0;" to global variables that does not have value, but I think now with the new MQL4 there will not be a problem for those variables to not have value.
Reuploaded again with this thing fixed.
More details about the last error? Maybe some link to a file to be included does not exists?
Does MetaEditor reports the same errors?
It really depends on what you want to do. You know that blocks are executed on every tick, so connect them in a way to get the result you want
This crossover thing is a little bit... You will see it! I have added 2 new blocks (and I will be quiet about them for a while) in Indicators section. I'm not sure if they will work as every human expect, but the crossover turns out to be something very relative. Look at the turnover option, I hope you will get it's idea, and if you think that the name "turnover" is not suitable, make me know so I can rename it
If "No trade is running" is on top (and Group numbers, trade type and market match), no trade will be created. This is as simple as this: https://fxdreema.com/demo/mt4-buy-now-i ... ade-exists
What you have on that picture is what you say you got. On every tick this gets some information from the last closed trade and the opens new trade. Until you have newly closed trade, it will just put trades one after another.
MT4 -> Tools -> Options -> Notifications
Някои неща сякаш са по-добре да се направят с чист код. Но ето едно предложение от мен дето ползва минимум блокове + 2 променливи: https://fxdreema.com/shared/ORnGmGpO
