MetaTrader 4 Client Terminal Build 211

New comment
 
New MetaTrader 4 Client Terminal Build 211 has been released.

What’s new:

1. MQL4: Fixed operation of function FileWriteString(). Now it works accurately to the documentation: «If the string to be written is shorter than the given value, it will be extended by binary 0s up to the given length.»

2. MQL4: Fixed error of passing string parameters into the imported functions of mql4-libraries.

3. MQL4: Fixed error of releasing histories of others’ symbols or timeframes after the Expert Advisor has been unloaded. Now the terminal releases the used memory in a minute after unloading of the EA.

4. MQL4: Fixed function MarketInfo() with parameter MODE_TICKVALUE. The returned value is not normalized anymore.

5. MQL4: Fixed error of forming variable last_error when calling an existing global variable using function GlobalVariableSetOnCondition().

6. Tester: Fixed error of recalculation in optimization when using data from another trade server. Now, if another trade server is used, the data will be recalculated.

7. Tester: Fixed displaying of the optimization graph by profit factor.

8. Tester: Modified algorithm of feeding the data preceding the test start date. Now 1000 bars will be added when any historical data are requested.

9. Tester: Improved data modeling algorithm. Ticks for bars with the volume of 4–6 are modeled more precisely. Fixed error of a false tick appearance at the beginning of the generating sequence when using dates «From» and «To».


The live update is available through the LiveUpdate system. Client terminal can be downloaded using "MetaTrader 4 trading terminal"
 
After updating to Build 211, in Strategy Tester (st) on EURUSD daily period, I get Modelling quality n/a on some tests. When st is run for date range 2007.10.01 to current date, I get Modelliing quality 90%. But, when test is from date range 2007.09.01 to current date, Modelling quaity is n/a. I've Downloaded data in History Center and still get n/a Modelling quality.

2007.09.01 to 2007.10.23 st results:

1. What are some possible reasons to get Modelling quality n/a on daily test period??
2. Does Modelling quality n/a invalidate st results ??

Thanking you in advance.
 
because mismatched errors more than 100. Before adjust your data

I don't understand. What do you mean "Before adjust your data" ??

Rosh, thank you. The re-download History data corrected the Modelling quality n/a problem. I'm not sure why the first time I re-downloaded History data did not work, but it did work this time. I appreciate youir response.
