Ever since I started seeing "30% History Quality" in my strategy Results tab (MT5), I've been searching for the reason/remedy. Now 11 days has past and I've still been unable to find a solution. I've set "Max bars in chart" to "Unlimited", I've "refreshed" the chart for like a million times, I've set different time frames (M1 ... Month), I've tried 6 different brokers, I've read tens (maybe hundreds) of posts talking about this same problem ... all in vein! I still have a "30% History Quality"!
I am really surprised! Strategy Tester?! Is it really a joke or something?
P.S. I am using Metatrader "5" (and not "4") in which there is no "History Center"...
In MT5 the necessary historical data is downloaded and automatically synchronized when you go to do a backtest. Logically, you depend on the quality of the data offered by the broker you are using.However, you can also manually force the download of the data you want. To
do this, right click on the symbol chosen in the Market Watch window,
choose Symbols option, a window opens, and select the Bars or Ticks tab
(as you wish), and there you can download the data, and you can also
import the data from external sources, as well as create custom Symbols with them.

No, it is not that bad and you already found the solution. It is contained in your post scriptum.
Have you tried using the "every tick" mode in the Strategy Tester ?? If the answer is "Yes", then change your broker or import your own historical data from external sources. For example in Alpari I get a quality between 89% and 100% depending on the selected period:
It also depends on the Symbol. Regards.
