it is necessary to have various methods to calculate things as
sometimes the built in functions do not always work as expected. eg
timeframe indaily for intraday ASX goes from 2pm top 2pm, this
coincides with midnight US time which we have to endure with our
datafeeds. Bit like wanting to scan on the Last days n=3 goes from 2pm
(ASX time) as start of day (Yes I have passed this to support)
