"Use symbol custom settings (change the sessions settings to keep them open at midnight)."

Is this possible with an existing symbol or do I need to create a custom symbol to do that?

In my case the availability of tick data is not congruent with trading time changes because of daylight saving time. Analysis of this problem:

Yes it's possible, just change the settings of the symbol in the Strategy Tester.

Hello

I've noticed that compiling my Indicators and EAs using build 2940 generates .ex5 files that are roughly half the size of pre 2940 builds. What's the reason for this?

Thank you.

Thank you.

MT5 works with 64-bit Windows only for now, and that is why the size of compiled files was reduced (it was 32-bit + 64-bit compilation in the past builds).

This is from official announcement:

For Metatrader 5 only, limitations:

32-bit terminals are no longer allowed to load programs from the Market.

32-bit terminals cannot connect to the hosting service.

The 32-bit MetaEditor version does not support additional file protection via MQL5 Cloud Protector.

MQL5 programs compiled under old MetaEditor versions (released 5 years ago or more) cannot run in the new terminal version.

New version of MetaTrader 5 platform build 2875: Improvements and fixes

...
Compilation time, on the contrary, decreased along with the size of EX5. We abandon the last remnants of compatibility with 32 bit versions and removed the generation of the second copy of the program specifically for 32 bits. This of course made compilation faster.

I have observed a bug with the calculation of M1 bars on synthetic instruments, using non-live data (whilst the terminal is not running).

This was not happening before the latest build.

Repro steps:

• Create a custom symbol, copy its settings from EURUSD for simplicity
• Use the following formula (this is a USD average index, but it happens with all of them): (1 / AUDUSD) * USDCAD * USDCHF * (1 / EURUSD) * (1 / GBPUSD) * (1 / NZDUSD) * (USDJPY / 100)
• Allow the terminal to calculate history for the instrument, then shut it down for a little while
• Open it back up, switch to M1, and wait for 10 minutes

You should now clearly be able to see that all the M1 bars that were calculated from non-live data have no wicks, whilst all the bars that are being calculated live do have wicks.

Expected behaviour: all candles should have wicks calculated correctly, not just those from live calculations

Many thanks

If this is not the correct place to have someone from the MT team acknowledge a bug report, can someone please direct me to who I need to contact?
