I just make function that can get my custom indicator value in mql4. But, i want to get all the history data from my custom indicator value. I know it work with changing shift value. But, i want to get the data till 7-10 years before or more. How can i do that ? Thanks before!
Do you have 7 to 10 years worth of price data for the symbol you are looking at from your broker in your MetaTrader 4 terminal? If not, you will have to download/import it from somewhere.
There are various "paid for" sources available.

I'm quite new to MQL so this may be a misunderstanding.
This code:
Print( TimeToStr( iTime(NULL,PERIOD_M5,i), TIME_DATE|TIME_MINUTES), iOpen(NULL,PERIOD_M5,i), iHigh(NULL,PERIOD_M5,i), iLow(NULL,PERIOD_M5,i), iClose(NULL,PERIOD_M5,i) );
Prints this:
2023.01.05 23:25, 0.91648, 0.91678, 0.91636, 0.91676
If I export data from the History Center I get slightly different numbers:
2023.01.05T23:25, 0.91646 ,0.91675, 0.91633 ,0.91675, 146
The values are just a tiny bit smaller. This is consistent - ALL of the values exported from the History Center are a bit lower than what I see when I examine the data with iOpen() etc. The difference seems to range from 0.1 to 0.3 pips.
I assume this is a Bid vs Ask thing. Is it? I understand the iOpen() etc returns Bid prices. But does the History database contain both Bid and Ask? Is there a way to see both prices?
Or it it just guessing? If so, it does not seem to be adjusting the prices consistently.
Edit: I am running in the Strategy Tester.
Edit2: Today I downloaded a bunch of M1 data from Dukascopy and imported it into MT4 History Center. Now I get exactly the results I expect from my program.
But my question stands, about the data MT4 downloads from the broker.
I have an elasticsearch instance that receives logs from multiple backup routines. I'd like to query ES for these logs from Grafana and set up a panel that shows the last time for the different backups. Ideally I would also like to be able to show this in color if the time is longer than a certain threshold.
Basically the idea is to have a display that shows, for instance, green if a certain backup has been completed in the last 24 hours, and red if it hasn't.
How would I do this in Grafana with ES as the datasource?
Exact implementation depends on the used panel.
Example for singlestat: write ES query and then select Stat: Time of last point, you may need to select suitable unit/format:
Unfortunately, Grafana doesn't understand thresholds in your requested time format (older than 24 hours). You will need to return it as metric (for example as age of last backup in seconds) = you will need to write query for that. That means, that you will have 2 stats to show (last time + age), so you won't be able to use singlestat. Probably table panel will be better - you can use thresholding based on the age metric there.
In addition to the great answer by Jan Garaj, it looks like there is work being done to make this type of thing much easier in the future.

I'm using Unified Remote for a while now and i made a working shuffle button for Winamp since that's very useful.
Since that would be a binary value, i would like to be able to retrieve the shuffle_state in order to change the button's text.
Looking at this page, i know that it's possible to give WM_USER messages of which id# 250 returns the shuffle state.
I'm just fiddling too long with the integration of this in lua, i can't get it to work.
Little help please? Thanks.
I am developing a billing system using PowerBuilder 12.5 Classic and I need to set 0 for a textbox; like in vb.net txtchange.Text = 0
i have two drop down list boxes
ddlb_price (defines the price value of an item)
ddlb_cash (the cash amount given by the customer)
sle_change (the change that the cashier is to give the customer)
the system should set the value for sle_change when the cashier inputs the cash.
1. this gives me syntax error;
if cash=price then
sle_fare.settext=0
end if
2. this gives 'incompatible types in assinment
if cash=price then
sle_fare.text=0
end if
The single line edit (sle) control is designed to hold text. You're trying to assign it a numeric value. You will have to change the number into a string if you want the sle to display it:
sle_fare.text = "0"
or
sle_fare.text = string(variableHere)
Once again, I'm going to step back, ignore the actual questions, and look at how a DataWindow would help as an alternative.
You seem to want a control with a data type behind it. The DataWindow has those types of controls. Don't forget that a DataWindow doesn't have to have a SELECT statement behind it; it can have a stored procedure, web service, or nothing at all (external DataWindow) behind the data set. Once you have a control with a numeric data type behind it, you get (for free) some basic editing controls, such as not allowing alpha characters in the field and making sure the entered value is really a number (e.g. "0-.2.1" would fail).
A step beyond that is looking at one of your coming requirements: calculating change. On a DataWindow, you can create a compute with an expression that will automagically calculate your change for you, once price and cash are entered.
I certainly don't want to say you can't do things the way you're proceeding, but there are many issues that a DataWindow would remove over some other approach. The strength of PowerBuilder is in the DataWindow.
Good luck,

Using ReportBuilder 7.X
Question
Is it possible to Control Print to File.
I need to change the Length of a field at print time
Example:
label2
In the setup - I set its length to 800 which is the max possible this field should ever be.
However, in many cases the record is less than that and i need to set it to the calculated size before printing to file.
Is this possible?
Is it possible to control any portions of this Print to file...at print time (before Print, after print)?
Are the objects avaiable?
We are registered users of the 10.x and above i believe, but have still not gotten around to recompiling are application in Delphi 2009 and the new ReportBuilder....so, that is not an option at this point.
Thanks
Shane
You can try to use the OnDataChange event of the tDataSource that you are using to link your data to your report. This event fires when the current record in the associated dataset changes. In that event, adjust your label to the size for the current record.
i solved this! Each control has a saveLength property. I can just use a global variable that can change at any time (controlling length of entire record). Then just before i print he label, i can set its saveLength property
thanks to all who responded though
