Dear Mr. Popov

I wonder if we can have bars from existed bars of data at selected by us periods during INPUT of data

We can have i.e. M2 or H2 data and still using FSB, with special input at entrance of data
or even Renko.

If this too much let us have acceptance of file of data, to a name we give.
We can create any file in 2 steps. once for period or renko in MT4 and once by using a modified version of your script to transfer

We can do also accept all existed data from MT5 servers. i.e H2, H3 etc using your script and then create opposite way charts in MT4.

I know. It is a lot of job.
