-2No Genetic Optimization in the Cloud Network
Which is the tech limitation to not allow Genetic in the Cloud Network?
Why do you think genetics are not available in the cloud? It surely works.
Not sure where you read that genetic optimization is not possible with the Cloud, as Stanislav said it should work.
The main difference is it can't use all agents as there is some links between different passes :
During genetic optimization, only agents of one access point are used. It is connected with the specific features of the genetic algorithm.
Hi guys, ty for quic reply
Before writing this post I already read all official guideline.
About 2nd question (GENETIC) the linked page explain:"The entire power of the MQL5 Cloud Network is used only for complete slow optimization."
So, it seems there is no chance to use Genetic optimization with Cloud network.
Am I wrong?About 1st questionDo you think there is a way to force using imported price data history in the cloud network?
Yes, wrong - it may be generic optimization as well.

tx Sergey, I will try!Could someone reply about question #1?
May I ask some additional question about how mt5 creates/uses 'selfmade' history data?
(I don't have mt5 on my laptop yet, so I can't try it myself.)
For mt4 I created my history tick-data file (fxt) for the backtests on the base of the birts script (eareview). My source are the tick-data from Dukascopy. I realised that whatever time frame I created all the fxt-files had the same size. I think this Is owed to the fact that each tick created its own 'data-point'. Therefore its size doesn't depend on the timeframe.
This is different if one uses the mt4 fxt files. As mt4 normally uses at least op,hi,lo,cl (maybe as well tick_volume..) to create 'artificial' ticks, which saves a lot of space and - I guess - calculation time.
Now you, siolibros, said:
This really surprises me!
My fxt-file with tick data (EURUSD60_0.fxt) has about 10 years and has a size of ~3 GB!!
So - am I right that you aren't using tick data - as 15 years EurUsd m15 has only 15 MB and an the end becomes 4 MB.
Due to the data formate of the csv-file of the tickdata (see here):
<DATE> <TIME> <BID> <ASK> <LAST> <VOLUME>
2017.07.03 00:03:47.212 1.14175 1.14210 0.00000 0
2017.07.03 00:03:47.212 1.14168 1.14206 0.00000 0
2017.07.03 00:03:47.717 1.14175 1.14206 0.00000 0
This needs a lot more space for one tick than in the fxt-file.
Ok now here are my questions about mt5, custom symbols, third party quotes and tickdata:
Thanks in advance!
2): Size does not matter. Every tick means every single tick. There is more ticks within 15 timeframe vs 1m timeframe. File size is therefor not relevant. More ticks = bigger file. Test with a broker or two (MT5) and you will note different brokers, different quotes and different quote volume.
Size does matter! Nobody knows the mt5 file formate and the size is a hint whether in the data file has single ticks or not but some data and a system to create virtual ticks (again)!
No - as you should have the same amount of ticks within a 15 min bar and 15 bars of 1 min!
Correct, but different timeframes built on the same tick data source should have the same size!
I have one tick data source (Dukascopy) so what you said it correct but irrelevant for me and my problem!
Again the formate of the data files for the tester is still not known, so practically nobody knows from where the ticks are coming - and therefore the size of the data files gives a hint.
Otherwise if you are optimizing a scalper on tick data you'll get 'optimal' parameters for the tick creating algorithm of mt5 but not for the reality - that why it matters!
Custom Symbols are still something very new and recent on MT5/MQL5 and are still being developed further, so there are currently some limitations on its use:
New MetaTrader 5 Platform Build 1640: Creating and testing custom symbols
More possibilities will be available in future platform versions
The development of custom symbols has not completed yet, and more
functions will be added in the next builds of the platform. You will be
able to import history to custom symbols straight from Expert Advisors,
as well as broadcast data (add quotes) of such symbols in real time.
Here are some other sources of information on Custom Symbols:
In MT4 FXT files, you have multiple very large files, each for its own time-frame.
In MT5, the files are stored as yearly history data files ("yyyy.hcs") and monthly tick data files ("yyyymm.tkc") files.
So there is no repetition for each time-frame, which greatly reduces the amount of disk-space as apposed to MT4 with its combination of HST files and rather large FTX files containing Dukascopy tick data.
Here is an example of the folder:
