Didn't find any, and I don't remember it here
roughly speaking, there is a bid, there is an average price of orders on the grid
a trawl is a bid minus the average price of the grid, compared to the specified step
If something goes wrong, you immediately go through the loop and cover the whole grid
this is a crude algorithm and it needs to be improved from the side of robustness, but it shows good results over short distances
By the way, I'm looking for ideas to improve algorithm stability.

My trawl works fine both individually and over the entire grid.
Have you read my question? I am not waiting for an answer from you but from the pros.
Yes, logically it could be, for example, the terminal has lost connection - there are plenty of reasons for that, I have had it lose connection 50 times a day.
What's the best way to get up-to-date prices, while being less resource-intensive, mind you - for a grid trawl.
So there aren't too many options...
Here is what I do: in order loop, after passing through all filters for symbol, magic number and type, I get the right price to a variable via SymbolInfoDouble() and make level calculations with it right before sending a trade request (if calculation gave such a result that modification is needed). You can also use SymbolInfoTick() - whatever suits your logic best. Of course, we can get not only one price but the whole set of parameters of the last tick, but sometimes it is enough to get only one price for a certain type of order - Ask or Bid and work with it, and get the other price for another order type at the next loop iteration anyway. That is why using the obtained price once before the loop may result in the risk of getting an obsolete price if the tick is missed due to prolonged calculations.
What if it doesn't get any at all? How do you slow down the cycle?
And this I left to everyone's discretion. But at the urging of users, I'll let you in on a huge secret...
do
{
d++;
}
while(!SymbolInfoTick(_Symbol, mqlTick) && d < 7);
Hi all!
Could you please tell me how to write tooltips/popups?
Roughly speaking, I need an indicator under a certain bar to draw an icon and when I click on this icon a small text with a description will be shown
Thank you!

SetIndexLabel
Sets the indicator line description text to display in the DataWindow and tooltip.
voidSetIndexLabel(
intindex,// line number
string text// description text
);
Parameters
index
[The index number of the line. Must be from 0 to 7.
text
[in] Text of indicator line description. NULL means this line value is not shown in DataWindow.
SetIndexLabel
Sets the indicator line description text for displaying information in the DataWindow and tooltip.
voidSetIndexLabel(
intindex,// line number
string text// description text
);
Parameters
index
[The index number of the line. Must be from 0 to 7.
text
[in] Text of indicator line description. NULL means this line value is not shown in DataWindow.
And for me, by clicking on the icon
Hmm, so it's a line.
And for me, when you click on the icon.
Whatever, you can do it on the icon.
Throw the fractals on the chart and hover the mouse over the icon.
Hello. Please advise how can if(MarketInfo(Symbol(),MODE_POINT)==0) be correct?
