I want to write a simple EA that would place grid of pending orders in one direction (E.G. Long) with the minimum - MQL4 and MetaTrader 4

Dimka-novitsek 2012.07.26 13:46 #2781

Please give me a hint. I haven't quite figured out how indicators work yet. My indicator does not draw when I change timeframe, and it draws once in a while. But sometimes it does, and it works exactly as I wanted it to! Please tell me what it needs.

Questions from Beginners MQL5 Building MTS on price Any questions from newcomers

Artyom Trishkin 2012.07.26 17:15 #2782

drknn:

You could put the ticket in global variables as well. :) You can roll the hell out of it at all. But as an idea selection of the order before modification will work. Only if it is not necessary to reset lots only 1 time for the whole order lifetime (with a single modification at that) :) :).

In short, there are a lot of variants :).

You can do it globally as well. But the terminal writes them into a file before closing (if memory serves me correctly). I.e. it will not save from loss of a ticket at unexpected power cut.

So far I don't see any more reliable way than to take data directly from the server when you need it.

Newbie question(:

Hello, I would like to write a simple EA that would place a grid of pending orders in one direction (e.g. long) with the following input parameters:

minimum price

maximum price

Number of orders between these two prices

TP - clearly up to the next order

SL - 0.

and not to pay attention to other orders which are not his.

In this case if one of the bids has played the same order should appear again.

The market price does not affect the parameters.

Example: Market price is 1.22.

set 1.23(min), 1.27(max), 5 (number of orders).

there should be a pending order at 1.23 - 1.24 - 1.25 -1.26 -1.27 (respectively with TP set to the value of the next pending order, except the uppermost one - it will respectively be 1.28).

p.s.: tried to dig in the code Setka but for me it is still a "dense" forest .... Can anyone help?

And it is desirable to separate the blocks and sign them - what is responsible.

Thanks...

Kind. If you "wanted to", write - they will look at the sane code here and correct it. Study the tutorial, documentation, exps from the site codebase.

What if it's not 60 quid but 70 quid worth of code? :) ;)

There is no free stuff here, if so far it is a "dense forest" for you, go straight to zhoba - they will write for food.

Gentlemen experts, if you send a newcomer to another place to write in place of "in zhobu" at least "in job" or "to work. I remember when I was a rookie and they sent me there, the first thing that came to mind was that they sent me to the asshole from here.

as you rightly sent me to the "zhoba"))

I'll certainly try writing first... ...even though I'm a nerd, so maybe I'll turn to artmedia70.

But in this case it turns out that we will be correcting code that someone is selling?! - does he mind?

And I think 60 is too much for this simple code... 30 imho. Then all this code will be converted and it will be about 700, which by the way I won't regret to give.

Too many thoughtful ideas, which correlate with the situation in the account.

thanks for the link to the tutorial.... found a description of the function of restoring a played order on the forum but the skeleton itself will most likely have to be borrowed from someone and corrected.

So...

Thank you all.

Can anyone suggest some free examples that are suitable for me? It's easy to prescribe an algorithm if you know the functions.

Hi, can you tell me how to find out how many pips an order is in profit?

For the selected open position you need to find the difference between its opening price and the current price.
