For MT5 CopyTicks, change ticks' times, build a custom symbol. I might help you with this, but I'll let you try doing it yourself first.
For MT4 you need to collect them as they are not available on demand. You won't have history.
And - the most important - write to MetaQuotes and ask them to implement seconds charts. If enough people ask they'll do it.
Thank you. I will try to write the codes. If I get problems, I will ask you. And I will write to MetaQuotes about the seconds charts implementation.
I use MT5. Could you give me a simple example? I find it difficult. Thank you.
Do not double post.
