What you are looking for is the Message.createReactionCollector method.

You first need to declare the object that represents the message on which you'd like to create the reaction collector. One way of doing this would be through a channel ID where the message is sent, and a message ID. Like so:

You can easily set the source of an image in JS:

document.getElementById("holla").src = "avatar.gif";

You need a few improvements to get to your desired target state:

1. It's not clear why you'd use setAttribute() to get data from an attribute. As its name implies, it is used solely for setting the value of an attribute. A better attempt would be to use getAttribute(), but in this case, since you're accessing a data-* element, you should probably use HTMLElement.dataset instead.
2. Unless you anticipate having exactly one element with the class image-parent, you should definitely swap your use of querySelector for querySelectorAll to ensure you get a NodeList of any/all matches instead of just the first one found in the DOM. In this case, you'll also have to use a loop for both (a) all parent containers matching your .image-parent selector, and another for (b) each of the img elements within that container.
3. Be a bit more specific with your CSS selector in your call to querySelector/querySelectorAll to avoid issues relating to trying to access attributes that don't exist by matching on elements that have the data-alt attribute in the first place.
4. Your desired end result shows that the data-alt attribute no longer exists on the parent container element; if this is actually desired goal, you don't seem to have attempted to do so in your snippet. Use removeAttribute() for this.

you can log all errors to file with the below and it will log even when DEBUG=False

Update: Try this.

This should work.

In flexbox I believe, justify-content:space-between; would probably do this. However it would set uneven gaps in between as your flex-items are not of equal widths.

And other option would be you can use CSS-Grid and all your children buttons would be of equal width:

So, on your parent element (which will become your parent container), you can use the following:

Although this is undocumented, the "string comment=NULL" parameter of the trade function OrderSend() in MQL4 is limited to 31 characters. If this limit is exceeded then the string is rejected as a whole and treated as NULL.

In your code, just before the OrderSend() function, add the following line:

You can do this using a word list of all English words. One place where this exists is in the hunspell pacakges, which is meant for spell checking.

Traditionally, almost everyone calls the third parameter to preg_match $matches, so I'm going to go with the nomenclature here.

If the RegEx matches, the third parameter will be an array with numeric indexes for each items, as well named-indexes if you have any named matches. So you are looking for:
