could you pls support on this one? After updating to the newest build I´m receiving the above mentioned error message when starting the Strategy Tester. Could you pls advice what this error message says - or better - what I have to do? Thank you so much!
You cannot get rates with wrong timeframe in Open Prices mode
Previous error is "EURUSD,M15 wrong timeframe ...." because your testing timeframe is H4 on EURUSD
The Open Prices mode of testing was changed in the build 619 (#12 in the list of changes):
Changed the operation of the testing method "on open prices". As
before, OnTick of an Expert Advisor runs only at the opening of the bar,
but instead of M1 OHLC ticks, high, low and close states the tested bar
are used. Due to this, stops and pending orders may trigger at a price
different from the stated one. This has led to a multiple acceleration
Peculiarities of using this mode are described in the Tick Generation section of the user guide:
In this mode, OHLC prices of bars of
the timeframe selected for testing are generated. The Expert Advisor
function OnTick() runs only at the beginning of the bar (at the Open
price). Due to this feature, Stop Levels and pending orders may trigger
at a price different from the specified one (especially when testing at
higher timeframes). But this allows you to quickly run an evaluation
test of an Expert Advisor.
The exceptions are periods W1 and MN1, for which bars are generated once a day instead of once a week or a month respectively.
There are some limitations on the "Open Prices Only" mode:
mode of all ticks generation is the most accurate, but the slowest one.
For quick, but rough testing/optimization, use the "Open prices only"
