We are going read values from Objects on the chart which are controlled by indicator, not values from buffers, that means, we dont need indicator in My Indicators because we are not going work with indicator directly.
Indicator must be inserted into chart manually (into same chart with EA).

here is indicator (note, is renamed, you can rename it as you wish)
0_1480901745242_Shved Supply and Demand (e600) length.ex4

and here is shared link to this strategy:
https://fxdreema.com/shared/JyxzKfdwd

now look how is this indicator working:

• is ploting dynamic zones:
  

• these zones are not from buffers, but from objects, so look how they are named:
  
  

See, Rectangle type with name begins as "SSSR" and than some incrementation with "R" or "S" and next info like "Weak", "Proven" ...

Our strategy can be (you can create another):

• when candle 1 closed inside zone, we leave EA waiting for next conditions
• when price go outside (next candle 1 closed outside) zone Up, EA open Buy, when outside zone Dn, EA open Sell
• zone width must be at least 1xATR
• SL and TP is some multiplicator from ATR indicator
• Lot size is risk percento from balance depending on SL

First we need 2 blocks which are selecting objects (rectangles) based on criteria:

next is switch which control if was price inside rectangle before and if EA is waiting for trade

after this are blocks which are working with selected rectangles
these blocks make some comparison with candle price and variable blocks save price from selected object into variables priceUp and price Dn for next comparison:

here are all blocks together needed for this strategy:

and this is result:

note: this is not profitable EA and is not for your real account, this tutorial shows only way, how to work with object from some indicators

note:

• with this way you can working with any object on the chart, also with own objects placed manually
• better if you give them name in chart and for selecting object you use block: "Select Object by Name"
• or you can read or compare values from objects also with other blocks:
  

that is all ...

Hi, I decided to share few tutorials, how to work with fxDreema.

All what I share is my style of creating EAs in fxDreema. If you are newbie, you can learn something here.

I start step by step, from beginners to advanced tutorials. I am not best in teaching somebody, also my english is not oxford, but I created a lot of EAs.

I share link with fully working EA where you find a lot of comments. You can work in this link, or better, you can generate mql code and import it into your new project to work with.
In next tutorials I will not commented all things, only news, or what I decided as important.
For next questions you can ask here in forum.

First tutorial is, how to create easiest EA, when 2 moving averages crosses, in this cross we open trade in counter-direction of cross. This tutorial is splitted into more parts, because I will show you how to make this "nonProfitable" strategy into human control to be potential profitable.

Click here for first part and enjoy:
https://fxdreema.com/shared/UOM1aUO5b

Here I show you how to work with trendline.

Use this example only with Demo account and learn perfectly how it is working. I am not responsible for your money losses.

https://fxdreema.com/shared/Q13po8uvc

In example I will open trade on 4 possible situations:

you need create trendlines manually (for this example, but you can do this also automatically with EA using buttons, check my previous tutorial how to work with buttons)

in EA give name for this trendline in condition, and also the same name in chart for your trendline:

and this is live example:
dont forget, right name for trendline in chart:

trade when price break your TL from bellow above (buy based on conditions for myTrendline1):

or Sell for myTrendline2:

and when you place myTrendline2 (for Sell trade) above price, you wait for Sell when it break it from bellow, like this:

you can improve this example by other things, like delete TL after trade is opened (to prevent open another trades when your first is closed) or other things ...

have a fun

fast tutorial how to find specific value in indicator history
my tip is, use Loop block

original project: 0_1488923868468_tutorial_loop.mq4
link: https://fxdreema.com/shared/CS0MvwQSc

here was question, how to find atr max/min values in specific period
https://fxdreema.com/forum/topic/4507/indicator-average-value-ichimoku
so we will find atr max and min and save it into variables for further calculation

1. create few inputs:
   
   and variables:
   
   values are saved into variables atrMax and atrMin
   variable atrNew is needed for temporary saved atr value and variable incr is needed for incrementation candle ID
   input lookBack is period where are you looking for values min max and atrPeriod is period of atr

2. next create this block connections:
   
   firstly you need null variables before loop start, atrMax is 0 but atrMin is "nulled" into high value because for further comparison

block Loop have in parameter lookBack period - it is, how many times is this loop repeated

next is save atr value from candle ID (variable incr) into variable atrNew:

block Condition for comparing if atrNew is > as atrMax:

if that is true, save atrNew into atrMax (atrMax=atrNew)

the same logic is for atrMin with slightly change in Condition:

3. after that atrMax and atrMin are saved and if loop find on lookBack period new atr which is higher/lower as previous, it is saved ... in that case dont forget for candle ID incrementation which is done with incr variable in next block:
   

4. with Comment check if it is working:
   

see, it is working:

...
the same logic you can use for moving average, RSI, stochastic, macd, custom indicator and all others

important note:
... be sure that each EA must have own variables file (1 EA >> 1 variables file), otherwise there will be a big fight between EAs .... 1.EA>>varSave1.txt ... 2.EA>>varSave2.txt ....

Sometimes we deal with situation, when EA have few critical variables and MT4 terminal must be restarted or was restarted by incident, these variables are no longer available and it can cause problems.
Values from history trades can be obtained from trades history, but sometimes can be calculation very complicated. For this situation exist another way how to avoid loss of variables. They can be stored into text file with every variable change. For this situation I prepared small example how to do it.

Example EA have two buttons. Try with tester.
https://fxdreema.com/shared/HtX9lP51c
After click on the button trade is opened (buy or sell). Here is small management with lots. When EA is inserted into chart, variable "varLotsBuy" get value from input parameter initLots1. After button click first trade (buy) is opened with "varLotsBuy". If this trade is closed with SL, variable "varLotsBuy" get value multiplied by input parameter "Lots1Multiplier". After new button click, next trade is opened with new value from variable "varLotsBuy". When trade is closed with TP, variable "varLotsBuy" is reseted from first value (initLots1).

0. Summary: initLots1=0.1, Lots1Multiplier=1.6
1. Buy: Lots=0.1, closed by SL
2. Buy: Lots=0.1*1.6=0.16, closed by SL
3. Buy: Lots=0.16*1.6=0.25, closed by TP
4. Buy: Lots=0.1

Example EA in chart:

EA is using few input parameters:

and few variables: (used are only varLotsBuy and varLotsSell, next variables are only as example)

on Init section draw two buttons and with Condition block (File exist) it check existence of "file with variables", if this file does not exist, EA continue with normal start (with nulled variables), but if file exist, custom code read and initialize variables from this file:

this is how code looks like:

strArr[20] is simple temporary array where values are readed from file, each line is one variable (size of array 20 can be increased to any higher size, depends on how much variables you need, it can by much more higher as count of variables, there is no strict rule)
at bottom of code are variables one after another, in my case they are:
varLotsBuy = (double)strArr[0];
varLotsSell = (double)strArr[1];
var0 = strArr[2];
var1 = strArr[3];
var2 = strArr[4];
var3 = strArr[5];
var4 = strArr[6];
var5 = strArr[7];
important are order and type of variables (order must be same as in file-write code)

on Tick section just open trades after button click:

and in on Trade section is calculation where variables are calculated/changed and re-saved into file:
(this saving into file can be done everywhere you need, in on Tick section, on Timer, on Chart ...)

and this how code for save into file looks like:

you see, pretty easy, nothing complicated .. variables are writed one after another with FileWrite function into new lines in file ... (once again, order of values in file is important, it must be compatible with file-read code)

File with variables is saved into MQL folder:

in case of tester it is file: tester\files\yourFileName.txt
in case of normal EA in chart: MQL4\files\yourFileName.txt

Note, that this file can be opened and edited also manually:

And when you need full reset of variables, before you place EA into chart, delete this file (or create input parameter for delete function, function for this is simple:
FileDelete(fileName,0);

I hope my explanation was not very complicated ... have a fun ...

Cheers ...

because you messed up it completely ... I told many times, and I repeat myself once again and again: zigzag is not simple for beginners (or not coders)
... and I'm banging my head on the table, why the hell I got this idea to create the zigzag thread, because instead of explaining how the zigzag works I do the whole project for people from scratch ...

https://fxdreema.com/shared/8Xeio059c

Anyway, this is my last reply for this ZigZag thread. Everything was covered here into details with many examples ... If you does not understand zigzag, read it once again, and once again. Notice also how important are block IDs - order. If you failed, give a break for zigzag and do anything other. Come back after a few days and read everything again and give a new try.

You can use the trick with "int" conversion, but then put the variable in the Text(code input) option.
Text (code input) option must be selected.

In tutorial 01 I showed how to create easiest counter cross EA, in this tutorial you will see how to add inputs into EA with fxdreema.

Click on this link with EA for more details:
https://fxdreema.com/shared/G8goTenZb

When you will directly import that EA without creating block after block, do this:

1. generate mql code and save it somewhere:
   

2. import this generated file into projects:
   

Now is EA imported in projects and you can start work with them.

See step 1. (description in EA). where I am talking about constants, constants in fxdreema:

For adding constant into block parameter, do this with mouse right-click in field where you will add constant and select this constant. Now is this constant as Input parameter. But when you use constant as input parameter, leave input check-box unchecked:

Why to use constants in fxdreema instead input check box? Because you can add the same constant into more blocks.

You have successfully created input parameters for EA. Values are changeable in tester.

Hope it was fast and clear.

Next tutorial will be about buttons for this EA.

It is not possible with integrated martingale systems in Buy block. You can do it only with a custom martingale system (using a combination of variables, blocks for checking trades count, creating a final variable for the comment in Buy block, ...)

It is called "counter trend trading" - in other words "selling tops, buying bottoms"

@l-andorrà
Don't worry, I am still here and I watch people to learn, to come, to try and give up and leave

@ferdinand-0
Hi, it depends on your trading style, some people buy when trends started, some sell tops Both is good if it is timed correctly, timing is crucial. As you move forward, you will understand it.

Try to find a moving average over CCI indicator.
https://www.mql5.com/en/market/product/54067?source=Unknown

I can work faster with custom code blocks, you can follow the logic and easily turn it into blocks
Note: onTimer section is not working with tester

here you go:
https://fxdreema.com/shared/oRBYGzxCd

Use onTimer section and set the interval for 1 second. Add a variable and increment it in this section (varCounter = varCounter + 1), and compare the result with the value 85. If it goes over 85, "allow opening" a new trade depending on another conditions (or open one immediately). By "allow opening" I mean set another variable for true (like varOpen = true). When a trade is opened, reset all variables (varCounter = 0, varOpen = false, etc.).
