Thanks for this, it will be most helpful.

MT5 data has about the same relaibility as MT4  none. Please keep in mind that there are going to be data problems with MT5 just as with MT4.

Dear Dr. Popov

Let us suppose I have one EA developed in FSB using M1 CSV data.

Suppose I use a Timeframe of M5 to calculate the behavior of one indicator used in development of the M1 EA

(I mean, I do use of Longer Timeframe of one indicator in Logic Conditions).

FSB what file uses to receive the information to calculate this indicator M1 CSV file or M5 CSV File?

Thanks in Advance for the answer.

Dear Dr. Popov

Would you please add a time offset to the above scripts in hours???

It can be very helpful to everybody as many brokers have different server times.
             

TimeToString(rates_array[i].time,TIME_MINUTES)

it can be             
             

TimeToString(rates_array[i].time+3600*TimeOffsetInHours,TIME_MINUTES)

Am I correct?

By he way, do you think there is no way to add a TimeOffset to an EA to "understand" bars of different time server like local server ones, against to change every indicator relative to time like BarClosing2 etc?

How to increase my data source period.

Each time I upload my data source using the script method, the new data over rides the old data,

i.e. from Aug 26 to Dec 2

after upload it becomes Aug 28 to Dec 4.  Two days of new data, replace the two days of old data (26 and 27 Aug).

How to keep all the old data so that my data source can keep building up over the years so that I have longer data period to develop my strategies to make it more "stable"?

Thanks

Thanks for your suggestions

The script prints the number of bars exported. If it is 100 000, search the problem in the MT settings.

what do you mean: Load a data in all periods of the symbol;

where do i find the MT files folder

you will know that i am computer illiterate by now......sorry

open MT4

top left is 'files'
click on files
click on 'open data folder'
click on MQL4

and you will see 'files'

Please, please. spend some time learning about MT4, use the internet and do some research.

Please do some reading about automated trading so that you grasp some understanding of the tasks ahead

Please get to know about FSBPro

This is a serious business and most people try to equip themselves properly so that they are not depending on others.

Hannahis,

I found your post regarding data source period – that downloading new data overwrites the old data. The script used to download data from MT4 instance on your computer can be adjusted to enable larger data set to be downloaded, by editing line 30 in the script. But the problem which I have encountered (and probably others also) is that my Forex broker will not allow me to scroll back more than a limited amount of bars. For M1 it will be around 2 months of data bars.

And I prefer to have my broker’s data bars to be used in FSB Pro strategy developments. In that way I am more sure that results achieved with FSB and then on demo/live account (with my broker) will be similar.

BTW, I am downloading data bars from Live Account and not from Demo Account, even if I have confirmed that both have exactly same values during the feed process.

My solution to enlarging the data set is to regularly (once a week) download data from MT4 instance and copy it to a separate directory. Then I will use Excel to “glue” additional bars from newly downloaded CSV file to the old downloaded file. It is a lite primitive solution, but it functions perfectly. It takes only few minutes.

Is there a way I can also change FSB Demo data to increase the maximum bar beyond 100,000?  So that with each new History Download, I can keep expanding the historical period and not such with the current 3mth period?

I tried to make the changes in FSB's user's file/system/FSB Demo data and increase default from 100,000 to 1,000,000 would this allow FSB to keep adding new historical data, expanding the period?  When I tried to download History Data, I see noticed the 100,000 default for 1min chart.  Did I miss anything?  Or this isn't the way to do it?
