I wanted to generate an offline chart (by the original PeriodConverter script) that is equal with the donor one. For example: EURUSD,H4 >> EURUSD,M57 (this came from EURUSD,H4 by InpPeriodMultiplier=1).
I used H4 chart as donor instead of M1.
I found that there is a missing bar (index 1). Current bar (index=0) is OK, index=1 misses, index=2 is OK and all others are OK too.
Modified converter is attached (only modification is the change of the name of offline chart to M57).
I hope you understand my problem and can help.
