any candle on tradingview --> if you open for example ETH/BTC on the exchange bittrex the last candle on 09:00 (exchange time) is the following:

Open: 0.07137
High:  0.0714
Low:   0.7096
Close: 0.7096

how is this calclulated?

I get the data stream from bittrex and see all the filled sells and buys but I don't know which data I have to consider in order to have the correct candles like in tradingview.
