==>
we offer many time frames.
we are getting data from various sources. BTC/USD, LTC/USD is from 3 global BTC,LTC exchanges and average that data out.
and different data is from data feeding suppliers. so we can not manipulate.
but, all data interval is 1 second.
you can compare to global public data .
I compared your Silver data with http://www.silverpriceoz.com/silver-price-per-ounce/. They are mismatch at decimal point. If u dont provide data sources and avg calculation formula, U r NOT provably fair. U can always manipulate and there is no reason to believe that U wont !!!
our silver data is not bid / ask price. it is also not average value, either.
it is index of silver. you can check http://www.cmegroup.com/market-data/delayed-quotes/metals.html .
of course, this site's data is delayed-quotes , but our data is real time data.
if you compare the site's data with our data, you will know our data is real.
you can compare to All instruments (except major currencies, BTC, LTC) data on this site.
we always thanks for your interest.
