A problem of cloud network must be solve, 4 of the 5 networks finished their task but one of them is frozen, so it spend more time than not use cloud network.

MQL5 Cloud Network is not ready yet.

 
Renat:

MetaTrader 5 client terminal is working only with own servers and their data. All detailed history (and M1 spreads) provided by trading server. No need to change chart history.

You can control quality of historical data from 'Results' page:

  • History Quality — this value characterizes the quality of price data used for testing. It is determined as a percentage ratio of correct and incorrect minute data. Incorrect minute bars are the ones having zero spread, or volume 1 when OHLC values are different. History gaps are also considered as incorrect data. Depending on size, the period of testing is divided into 1 — 199 intervals. Then the history quality is determined for each of them separately. Those time intervals are shown on the graphical indicator of the history quality (the lighter tint of green is the better is the quality, the red color represents intervals with the quality lower than 50%).

Hey Renat,

Thanks for the reply.  This is probably not the thread for this discussion but I will ask anyways:

Does the "History Quality" test for gaps in the history?  The last time I used MT5 was when I detected a 6 month gap in the GBPUSD data and I refused to use the tester further until a history import function is implemented.

The problem with using only one set of data is different brokers have different feeds, and because I don't trust the MQL data.  On timeframes < 1H this is a huge problem, and a strategy should be tested on different sets of data to test for any broker dependencies that the strategy might have, therefore a history center such as available in MT4 is a neccesity for any data mining application.

Must have missed that part sorry for that :) 
 

I see my MetaTester Agents Manager have some weird statistic...

 Local Statistic:

Test passes: 6596

Time taken: 7 hours 50 minutes

MQL5 Cloud Network Statistic:

Test passes: 17

Time taken: 0 hours 0 minutes

 I don't run optimization recently and I believe someone have access to my agents for testing. Could I suggest add a alert when metatester agent is used by third party!!!

Don't worry, we are testing MQL5 Cloud Network.
 
is it possibe to anyone try the cloud network?
 
This is indeed a big step as cloud computing has been the latest advancement in the field, though a lot would find it a little vague looking at its description.

I am intrigued how this would affect local developers who thrive on producing and marketing on client specific modules rather than a centralized function distributed across networks.
