Why is there a difference between the candlestick data on coinigy versus the data that binance provides? The candlestick data on coinigy.com does not match the binance official API. See the screenshot below: 



Especially the open and close are very different, does anyone know why this is the case and if I can get the historic candlestick data from coinigy itself?

I think this is pretty weird because Coinigy is there for technical analysis and should be accurate.
Coinigy appears to use data from multiple exchanges, whereas Binance is just one exchange and their data is only for their exchange only.
