Hello everyone,
I currently have Samuel's EA running on a demo account and I am quite satisfied. Good programming!
It shows good trading from time to time, but it has a weakness:
SELL options pile up at turning points in the valley of the charts and the same at corresponding peaks with BUY options, which then first hit the books massively as negatives. I would like to reprogramme this, i.e. BUYs in the day, SELLs at the peak, and so far my attempts have failed. I also only have a rudimentary knowledge of MQL5.
Can anyone help me?
SG and many thanks!
This usually doesn't work because the other points at which the EA takes a profitable position are then also reversed ....
But read this:

With the hints there you can specify your idea more precisely, be it just for you to see if it works, or be it to ask someone to do it, with or without payment.
Hello everyone (Especially the dear author)
I coded along with this article. I enjoyed it a lot and learned a lot from it.
Thank you for writing such an informative article.
However I have a problem. My EA did not place any orders. I downloaded the author's code but it did not place any orders too.
Since the article is 13 years old, I assume that the code is now outdated. Can anyone help me out?
My code is in the file below. Thanks anyone in advance.
Hello, I want to warn you that I am a beginner, so don't swear much if anything)
I wanted to create an Expert Advisor through the generator (and everything seems to be fine, but there is one but)
I would like to open a deal not immediately after the previous one closes, but for example after one candle,
I tried to write something, but in the end it gives an error.
Can anyone help with this, or indicate what the error and how to fix it?
and here is the actual code:

Hello everyone😊
@Mario31415927
This is simply because in the ticker, every time a new period or new bar (whatever) the variables:
are reset, regardless of whether positions are already open or not.
This can be found relatively quickly in the code.
However, the question arises as to whether this was intended, and if so, how are all positions closed again?
Perhaps I don't understand the TRADE_ACTION_DEAL order type in this context?
The trade order process could also simply be adapted to the trade class Trade. Like for example:

This explains the difference and the relationships between orders, positions and deals. The latter reflect the booking processes on the broker side.

Hello Carl,
thanks for the tip!
However, I must correct myself.
It is true that the variables are reset for each new time period:
But they are subsequently set again if there is a position accordingly.
However, I am experiencing the phenomenon that the buy (POSITION_TYPE_BUY) is correctly queried, but not the sell (POSITION_TYPE_SELL). The variable is simply no longer set?
I have to debug the code step by step. This can only be a logical error😉
Sell_opened = true; // It is a Sell
Oh dear, I'm so on the ball today.
It is only queried once. That's the error;-)
All positions should be searched as follows;
It was indeed an error, it seems to be a web file.
I rewrote it myself based on the content and uploaded it. I don't know if there are any details because I'm new to this. Hope it helps.
