Try running the code below in our [GraphQL IDE](https://graphql.bitquery.io/ide) and you’ll get the data relevant to Candlestick charts.
```auto
{
ethereum(network: bsc) {
dexTrades(
options: {asc: "timeInterval.minute"}
date: {since: "2021-06-20T07:23:21.000Z", till: "2021-06-23T15:23:21.000Z"}
exchangeAddress: {is: "0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73"}
baseCurrency: {is: "0x2170ed0880ac9a755fd29b2688956bd959f933f8"},
quoteCurrency: {is: "0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c"},
tradeAmountUsd: {gt: 10}
)
{
timeInterval {
minute(count: 15, format: "%Y-%m-%dT%H:%M:%SZ")
}
volume: quoteAmount
high: quotePrice(calculate: maximum)
low: quotePrice(calculate: minimum)
open: minimum(of: block, get: quote_price)
close: maximum(of: block, get: quote_price)
}
}
}
```

isnt it the same query as the one in the tutorial code ? and Yes i tried it yesterday just to make sure that the query does return something , and it was giving the relevant candle data
but then again why does it return empty array when its used inside of bitquery.js in the tutorial ?

I just checked the API call and it seems that
```auto
const response2 = await axios.post(Bitquery.endpoint, {
query: Bitquery.GET_COIN_BARS,
variables: {
"from": new Date("2021-06-20T07:23:21.000Z").toISOString(),
"to": new Date("2021-06-23T15:23:21.000Z").toISOString(),
"interval": Number(resolution),
"tokenAddress": symbolInfo.ticker
},
mode: 'cors',
headers: {
"Content-Type": "application/json",
"X-API-KEY": "YOUR UNIQUE API KEY"
}
})
// Console logging the query result -->
console.log(response2.data.data.ethereum.dexTrades[0].high);
const bars = response2.data.data.ethereum.dexTrades.map(el => ({
time: new Date(el.timeInterval.minute).getTime(), // date string in api response
low: el.low,
high: el.high,
open: Number(el.open),
close: Number(el.close),
volume: el.volume
}))
```
the query does return the data from the API. You just need to console.log(); in order to check it if you want.
```auto
console.log(response2.data.data.ethereum.dexTrades[0].high);
```

dexTrades returns an array and hence to get a single value of a candlestick property, you might need to iterate over the array

Try removing the “tradeAmountUsd: {gt: 10}” from your query.

Any information on how to subscribe to bitQuery. I’ve been working on a project similar to this and I can’t get a live chart no matter what I’ve tried. Any information about this would be greatly appreciated.

Hi @cryptoMav you can refer to this tutorial as it is the updated one [Integrating Tradingview’s Technical Analysis Charts with Bitquery GraphQL API using VueJS](https://community.bitquery.io/t/integrating-tradingview-s-technical-analysis-charts-with-bitquery-graphql-api-using-vuejs/343)

You can smoothen the data through a few filters like
`priceAsymmetry` - use something like `priceAsymmetry: {lteq: 20}`, this basically removes trades where both sides of USD price difference is more than 20 dollar.
`tradeAmountUsd` - use something link `tradeAmountUsd: {gteq: 1}`, this basically remove trades less than 1 dollar.
let me know how it worked.

This is correct, how you are comparing the charts? Which service you are using to compare our charts?

Hi, Thanks for response i already solved my problem by changing timeInterval to 1min
```auto
timeInterval {
minute(count: 1, format: "%Y-%m-%dT%H:%M:%SZ")
}
```
but when i changing the chart to 5mins it will not load but it shows no error on console i think the problem is updating the chart, its hard it to me i can’t find any documentation about this
