'ZipLocalHeaderOpen' has constructor and cannot be used as union member    ZipHeader.mqh    52    23

Thanks fxsaber, now it's all ok!

The archive of third-party ticks has already reached 5 GB (10800 files). Unpacking+parsing takes 6 minutes - 860 million ticks.

When you work with such large numbers, brakes appear in places you rarely pay attention to. For example, getting a list of files or ArrayResize.

• A lot of work has been done to fight "bottle necks".
• Added even more detailed logging.
• Resolved compilation issue on new MT5 builds.
• Made small but sometimes important fixes for further work with generated custom symbols.
• Code became ugly in some places.

The update will be available after moderation.

Thanks for the update

When parsing is going on hundreds of millions of values, every operator in seemingly optimal code starts to play a role.

I made tuning, increasing the speed by 1.5 times - 4.5 million MqlTicks per second. It is only twice slower than CopyTicks.

Hrenfx got sucked into the fifth metac. But at first he was on the right path - writing his own counting. :)

Updated to working state.

ZY zip-archive is not actual - contains old version.
