If during long execution on cold (with upload from server) CopyTicks make order modification, it will happen (not on Server, but in Terminal - OnTradeTransaction) with significant lag.

For example, in normal mode 100 ms, in higher mode - 2000 ms.

Need to learn how to work with ticks sparingly somehow. Not working out.

How to make CopyTicks by nearest ticks fast and not consume hundreds of megabytes?
