well yahoo, irrespective of exchange appends EST as their time stamp. myQuotes adjusted the timestamp as provided by yahoo to local exchange time.
if you are following NSE then its wise to keep the settings as India only and then adjust ami for local time (Saudi time for you).
will see if i integrate a customized time settings.
backfilling can be done through my
other app although you have to manually do the same.
yahoo backfill is delayed by 15 minutes. again since it is a one time process i havent integrated the same.
but what really interesting is google. the data integrity of google is very good and way above yahoo. hope google have a RT link soon. try out this
backfilling app
thanks for your feedback
cheers
