Maybe you missed something, it's confusing sometimes, because by default the location of experts/indicators/scripts is somewhere in AppData... weird place. Go to File -> Open Data Folder in MetaTrader to see the exact location.
By the way, Revo Uninstaller is also made in Bulgaria 
If you ask whether it is possible to edit indicators, it's not
Какъв беше тоя индикатор... всъщност няма значение, по-важното е да знаеш как да си го нагодиш. Ето и малко теория...
Индикаторите комуникират с експертите през буферите - индикатова записва там информация, експерта може да я чете. Всеки буфер е масив от данни, което е нещо като таблица с 2 колонки. Едната колонка са ID-тата на свещите, другата колонка са стойностите за съответната свещ. Ако експерта иска стойността от 2ри буфер за 15та свещ, тогава експерта пита за това - buffer 2, candle ID 15.
Да се отбележи, че номерирането на буферите започва от 0. На графиката като цъкнеш на свойствата на индикатора, можеш да видиш всички буфери там дето е Colors.
Винаги всички буфери са пълни с информация. Ако имаш 200 свещи и 5 буфера, като брой стойности това са 200 х 5 = 1000. Ти обикновено четеш една стойност от един буфер Информацията винаги е число. Ако индикатора е тип MA, всички стойности са някаква цена. Ако обаче е тип прекъсната линия или стрелка дето се появява от дъжд на вятър, тогава при неактивните свещи стойнстта е ... прието е да е максималната 32/64 битова стойност, едно голямо число. Като константа в MQL4/5 е известно като EMPTY_VALUE. Понякога обаче е 0, зависи кой е правил индикатора. Но да кажем че е EMPTY_VALUE.
Ако имаш индикатор тип MA, тогава си четеш която стойност искаш и толкова. Ако е прекъснат тип, тогава ще търсиш стойности дето не са EMPTY_VALUE. Има примерно един блок Indicator Appear, който засича моментите когато стойността преминава от EMPTY_VALUE към нормална стойност (текущата цена). В тези моменти се появява стрелката на индикатора, или линията, или там каквото е.
Проверявай индикаторите с Indicator tester - това е блок дето визуализира стойнсотите на индикатора върху графиката за всяка свещ, та добиваш представа как работи. Също чертае и розова линия. Би трябвало да виждаш променливи стойности във времето. Ако стойността е винаги една и съща (най-вероятно би била EMPTY_VALUE), тогава пробвай с друга свещ, сложи Candle ID на 1. Такива са обикновено индикаторите дето показват стрелки - те ги показват на предишната свещ. Даже Fractals ги показва на третата свещ.
Понякога при добавяне на индикатор в програмата се случва да обърка някой буфер или броя на буферите - проверявай ги чат пат
What is your spread? There is a spread meter on the lower left angle. When backtesting you can also manually set it. I normally put mine at 20 or 30 (for 5-digits markets like EURUSD), which is 2-3 pips.
It's also normal to see buys above the price on M1, because buys are executed on the Ask price, which is not visible on the chart by default.
This one has 2 buffers - 0 and 1, green and red. It seems that fxDreema is confused and decided that there is one more. It's interesting that the same thing happened with another indicator to another guy today
Otherwise the indicator is working with buffers 0 and 1, I just checked it. The only thing is that it is slow as hell for backtesting
Some guys are writing to me that the documentation is poor. From now on I will tell them that nobody reads it anyway https://fxdreema.com/documentation/proj ... 0variables
I will suggest the description of "Condition" block 3 is not a correct value for "Adjust", because unfortunately, this input field cannot read our minds and it does not know what 3 is - 3 apples, 3 pips, 3 pips above, 3 pips below, 3 whatever....
Go in your fxDreema/Data folder and find somewhere... MQL4/indicators/
Inside, there are files that represents indicators that you have added. One of them is the broken one, just delete it.
It's only possible to add 1 EA per chart, this is how MetaTrader 4/5 works. But you can add as many EAs as you want, each for it's own chart... or until the PC dies 
Well, in fxDreema you can select specific timeframe for blocks. Also, there is a block "Set current timeframe for next blocks" that can basically emulate having two EAs on different timeframes.
Also, the same EA can work with different groups of trades/orders - have a look at the "Group" parameter that exists in all trading blocks
This is not a simple parameter, this is part of the MQL4/MQL5 code. It's content is not just simple "123" or "iamvariable", it can be a complex formula. Input parameters of the EA are simple variables with their values. But you can define a Constant, it will become an input parameter for the EA, and use it in Adjust with it's MQL name.
If this is for your manual orders, I will suggest to set "Magic Start" to 0, as they have magic number of 0. Or look at the group mode parameter in blocks 2, 9 and 14.
I'm not sure about the & letter, can you try with indicator name that does not contain that 
Well, after I launched this website I still didn't know how to enable EAs (AutoTrading button), so... 
It works with both for me here: https://fxdreema.com/shared/iQLjqkP2 It's most probably something else that is wrong 
I never thought about that and there is no such block, but it will be probably easy. There are two simple native functions:
http://docs.mql4.com/dateandtime/day
http://docs.mql4.com/dateandtime/dayofweek (Weekday filter block is using this function actually)
These can be used directly in Condition -> Value (numeric). So my idea is, if the current day is <= 7 and the day of week is == 5 () or you can use Weekday filter), then this is the first friday of the month.
Use Value -> Numeric -> select the Variable here. "Global variables in MT4" are something else
Block 1 should prevent block 10 from running twice and creating second buy, are you sure that there is no other EA running in some other chart? Also, "Once per bar" happens once (per bar), so even from here there is a limit for max 1 trade per bar.
"Indicator is visible" should be used here. You are on a right track, but as you can see, it's not a very elegant way of doing this with blocks. It's much better to do it in plain code, because it's just a simple loop, "break;" is a good idea and also some cache can be used (to not repeat the same job over and over again).
I will eventually do this somehow - in the Condition block or as additional block, I still don't know how it will be better (because this is not the only thing that can be extracted from indicators).
Something that will not make the EA slow will be to do it "in the future". Let's say you have 2 variables. When a new fractal is detected, then you modify their values. But in this case the EA needs to work for some candles until 2 arrows appear. Well, if you put a loop in "on Init", very similar to what you have now, then you will have maybe the best way of doing this - it will work from start and it will work fast.
There are conditions and conditions. In your case, both conditions are crossovers of two different indicators. But the crossover happens in one candle and then it's over. At least one of the conditions should be > or <, and I wrote about this above.
If you think that after the first condition becomes true, the second one waits to become true... this is wrong. Here is why: https://fxdreema.com/demo/mt4-wrong-closing-rule
Blocks 60 and 61 are executed on every tick, again and again. While you don't have any trade, blocks 55 and 57 are also executed on every tick. If the condition in block 55 is true, only then 62 will be executed (in the very next moment, not within seconds or minutes or hours). If the condition in block 57 is true, only then 63 will be executed.
