Hi @kave
For me the solution was to stop using the auto-import & use Custom MQL Code blocks to import custom indicator data by using iCustom.
The issue may have been caused by the fxDreema import or maybe something in my custom indicators, either way, writing the raw code to import inficator values works 100%.
Hope this helps.
Remove #property strict if exists.
Fixed it for me, many thanks.
You need to make a note of the offending block title.
In my case "cl;"
I thought I had deleted it but it became the name of another block on another tab and caused the exact same problem. I managed to carefully rename it to 1234 and then refreshed the browser.
Then Ctrl-F and try to find any blocks with the name "cl;". Only when I confirmed that there were no blocks on any tabs with that name was the problem completely resolved.
The lesson: Thou shalt not use anything other than alphanumeric names for blocks.
I have experienced the same issue but trying 3 different browsers, clearing cookies & rebooting didn't help.
I then tried to delete all the blocks on that tab and found that one block refused to delete. I had inadvertently entered a semi-colon when giving the block an alphabetical name rather than a number.
I tried to change the name but it wasn't having any of it.
The Solution that seemed worked for me:-
However, it's now occurred again on a different tab and I cannot find a reason for it . . . something is going on . . .
Would it be possible to not use an array but use a simple integer instead ? When I build indicators I check for once per bar by populating an integer ThisBarStartTime = Time[0];
The BIG issue here is that when an EA is running live an array out of range error stops it dead in its tracks and no further actions can be taken. There is no way to create an alert, push, sms or Telegram meassage to the user because it has simply stopped working. Therefore it ends up with orphaned trades unless they can be identified and managed by reapplying the EA to the chart.
Instead of allow an array our of range error to occur, would it be possible to allow the code to continue and do further checks, i.e. look at the timeframe and check some other flag to see whether it has already been actioned yet on this bar. Then allow it to continue and maybe flag an alert to say there was an issue but at least the ea continues to run . . . . ?
Thanks for looking into it. Appreciated.
Yup, that's the issue, there doesn't appear to be a smoking gun. I've added a raft of logging messages to try and gain more insight when it happens again.
I have started getting Array Out Of Range errors.
The EA starts & runs for a while and then simply stops.
To fix a bug you need to replicate I haven't yet managed to find a series of events to replicate it.
The error always points to the same area of "core" fxdreema code:-
datetime new_value = time[0];
This code appears under the heading:- // "Once per bar" model
Judging by the last message before the error occurs I believe it is happening immediately on the start of a new bar.
Any thoughts please ?
Within the fxdreema blocks there are many fields for users to enter either a value or reference a constant / variable.
Also rather than looking up a variable I am familiar with typing the name and adding a prefix v:: in front of variable or c:: in fron of a constant.
My question is how do I add a value from an array ?
For example . . . Lets say I have created a double variable called Lots[10] and I want to insert value Lots[5] into the Buy block field . . . "How much"
I type in Lots[5] or v::Lots[5] but neither work. I always have to convert Lots[5] into a non array variable first to pass to the field.
If anyone knows what I am doing wrong / how to do this it would be greatly appreciated.
Many thanks

Hi roar, Yes you are right, there is plenty of scope for improvement and de-duplication of blocks. I'm getting better each project but also this is quite a large project in it's own right. fxdreema has confirmed it was a temporary change whilst testing the above issues and all is back to normal again today.
And Yes, I do accept your challenge . . .
Thanks
@fxDreema have you implemented a maximum block limit per project ?
Suddenly today I tried to add a new block to an admittedley large project and it says "For techincal reasons the maximum number of blocks that can be created is ____".
I must have been operating well above the max blocks limit for months and never saw this message.
Essentially my project is now unable to be worked on unless I somehow find a way to dramatically cut the number of blocks which isn't possible.
Is this something that has just been imposed ? Is it related to the other issues in this thread ?
I really hope you can make an exception for certain projects as I have been using fxdreema for years and never been aware of this restriction.
Please help. Thank you.
Managed to incorporate the "NumberToString" function put forward by nicholish en at end of page one of this mql5 forum thread 135250 (Google: NumbersSeparator() function for Print big numbers).
This allows numbers to be automatically formatted with commas by using a new function:
NumberToString ( numbertoconvert , decimalplaces )
//+------------------------------------------------------------------+
#include<Strings\String.mqh>
template<typename T>
string NumberToString(T number,int digits = 0,string sep=",")
{
CString num_str;
string prepend = number<0?"-":"";
number=number<0?-number:number;
int decimal_index = -1;
if(typename(number)=="double" || typename(number)=="float")
{
num_str.Assign(DoubleToString((double)number,digits));
decimal_index = num_str.Find(0,".");
}
else
num_str.Assign(string(number));
int len = (int)num_str.Len();
decimal_index = decimal_index > 0 ? decimal_index : len;
int res = len - (len - decimal_index);
for(int i = res-3;i>0;i-=3)
num_str.Insert(i,sep);
return prepend+num_str.Str();
}
//+------------------------------------------------------------------+
Then whenever number formats using commas are required use:-
NumberToString ( numbertoconvert , decimalplaces )
Output will show as 1,234,567 rather than 1234567.
OK I have now managed to import a dll using fxdreema:
To get it to work I had to make sure the first block in OnInit is "Pass" and the next block is the DLL import block with no other blocks after it. I then started a separate "Pass" block to conduct the remaining OnInit actions.
Thanks jstap, so are you saying just use a single instance of Once per bar ? Does using multiple instances of Once per Bar cause slow down ?
I would be interested on opinions as to which method is better to ensure a faster EA:-
Which is faster ?
a) A single "OncePerTick" followed by a long string of blocks to work through
or break the blocks down and use multiple "Once per Tick" blocks ?
I appreciate "it depends" but any insights as to best practice would be appreciated.
Many thanks
I've searched the forum but unable to see a way to format numbers using commas as separators when adding to comments on screen.
For example 34567 would display as 34,567
Does anyone know if there is a built in function to achieve this or have a code snippet for such a function.
Any help appreciated,
Thank you
Thank you both for your input, @TipsyWisdom, tried your suggestion but didn't notice any change.
@l-andorrà the text blocks work well, it's just that I use a fair few and lining everything up / making changes takes time whereas the Comment block takes care of simple alignment and has the advantage of being manually moveable.
My "solution" which is a cludge is as follows:-
Wingdings charachter 32 is blank and this successfully removed the text from the screen.
I then created a button to turn the comment block on / off and so far it works.
I am not familiar enough with MQL to appreciate why a comment block cannot be deleted (yet?) but this workaround seems to work.
I still have not discovered a way to delete, ie completely remove a comment blcok from the chart.
I can update values by feeding variables into the value fields.
I am trying to pseudo turn comments off by inserting a "." and changing the text color to match the background, however although my color variable successfully sets the start text color it fails to update the color when the color variable is changed and comment vlock re-run.
Is this a bug, intended or am I doing something wrong ?
I have tried using both string and color variables to change the color.
