Its possible to convert periods to any timeframes, such as 3min, then conduct that 3min offline chart and it retains updating provided that the period convert remains running onto the M1 chart.

Is it feasible to conduct a'server time converter' upgrading offline charts?

Some brokers have 6 Daily candles per week when their host time is EST or other. I have EAs that operate on D1 signs from regular 5-day-per-week NY closing pubs. They're with brokers such as (old)Oanda and MB-T. The only solution is that a period converter style script put on the server period and operate the EAs on offline charts.

Does this exist? Is it possible?
