Title: Candles in Tradingview Post by: Wiss on June 27, 2018, 05:12:05 PM Hello,
I am trying to calculate based on ticks data of bittrex candles. I would like to have the same candles like in trading view: What is the correct calculation? I get all buys and sells during a minute. a.) do I have to consider all price update? b.) or just Sell or Buys and build on that my candles? If b.) which should I take in order to have the same pattern like in tradingview - Sell or Buy? thx Title: Re: Candles in Tradingview Post by: coinalyze on June 28, 2018, 08:45:20 AM take first buy/sell trade price, this is candle open price
take last buy/sell trade price, this is candle close price take maximum of trades prices, this is candle high price take minimum of trades prices, this is candle low price Hope that is what you need. Title: Re: Candles in Tradingview Post by: Wiss on June 28, 2018, 08:47:31 AM really?
What I understoood is that it is a BID Candle or a ASK Candle (so I have to consider that trade type) or? What I read is that the candle is a BID candle so I have to consider just the SELLS or? Title: Re: Candles in Tradingview Post by: coinalyze on June 28, 2018, 08:54:29 AM what candlesticks exactly you want to build, can you show on tradingview?
Title: Re: Candles in Tradingview Post by: Wiss on June 28, 2018, 09:03:54 AM 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. Title: Re: Candles in Tradingview Post by: coinalyze on June 28, 2018, 09:14:39 AM You need a stream of trades, like this one https://www.bitstamp.net/s/examples/live_trades.html , see here documentation https://www.bitstamp.net/websocket/ . Record all trades during 1 minute and calculate open, high, low and close prices as i described above
Title: Re: Candles in Tradingview Post by: Wiss on June 28, 2018, 09:17:21 AM ok thx I have the stream and all data but I can not build exact the same candle like in trading view - I have problems of close and open
take first buy/sell trade price, this is candle open price take last buy/sell trade price, this is candle close price take maximum of trades prices, this is candle high price take minimum of trades prices, this is candle low price So you mean that I dont have to consider if it is a sell or buy right? I will consider all datas.... Title: Re: Candles in Tradingview Post by: coinalyze on June 28, 2018, 09:23:51 AM yes, trade type(buy or sell) doesn't matter, take all trades
Title: Re: Candles in Tradingview Post by: Wiss on June 28, 2018, 06:01:37 PM ok thx i checked my implementation once more and I implemented it exactly like you mentioned but there is still a problem - i get the following data:
28-06 19:54:41 FINE Added Streamdata: Time : 19:54:40.00487 Price: 0.07151 Name: BTC-ETH Nounce:26450 Ordertype: BUY Filltype: null 28-06 19:54:41 FINE Added Streamdata: Time : 19:54:40.00487 Price: 0.07150999 Name: BTC-ETH Nounce:26450 Ordertype: BUY Filltype: null 28-06 19:54:41 FINE Added Streamdata: Time : 19:54:40.00487 Price: 0.07150999 Name: BTC-ETH Nounce:26450 Ordertype: BUY Filltype: null 28-06 19:54:41 FINE Added Streamdata: Time : 19:54:40.00487 Price: 0.07131646 Name: BTC-ETH Nounce:26450 Ordertype: BUY Filltype: null in this special case the milliseconds are exactly the same - tradingview ignores the last 3 updates and shows an price at 0.07151 in my view the price should be 0.07131646 (and this causes my problem at the open and close) any ideas on this? Title: Re: Candles in Tradingview Post by: Zadicar on June 28, 2018, 06:10:48 PM 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: No calculation since those are numbers where the price did hit up a on particular timeframe. If you do see a candle each do have labels or indicators on where price do open and it do close and its recent high and lowest low. Letsa say a 1 minute candle, beyond those moving price its being record up until it opens a new candle on next minute and so on.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. So you mean that I dont have to consider if it is a sell or buy right? I will consider all datas.... Title: Re: Candles in Tradingview Post by: tambok on June 28, 2018, 07:08:06 PM Maybe it may 70% accurate but just don't rely to it especially if you are unsure, there are still ways for you to read the market so don't just stick with one method it is okay too to be involved with group of people that knows trading so you can share ideas with each other.

Title: Re: Candles in Tradingview Post by: ivankoh on June 28, 2018, 10:12:34 PM really? Using a technical analysis of candlestick charts on a trading platform is one of the basic knowledge traders need to master in order to invest in this market. I think that if using good tradingview then trader can fully determine the point buy and sell reasonably optimize profits thereby.What I understoood is that it is a BID Candle or a ASK Candle (so I have to consider that trade type) or? What I read is that the candle is a BID candle so I have to consider just the SELLS or? Title: Re: Candles in Tradingview Post by: rain_road on June 28, 2018, 10:54:36 PM When looking at the candle in the tradingview software I can predict the market is going up or down to prepare. That is because I know technical analysis. However, I can only predict in a short time.

You should order the trades by time. Look at last two trades. Sometimes trades does not comes in order... Title: Re: Candles in Tradingview Post by: Wiss on July 01, 2018, 03:51:55 PM yes thank I have seen that now too!
