Here is an article on how to simplify
Simpliftation of Ethereum flow data: a step -by -step guide
When it to real – time market, samplicity is essential. In this article, we will show you to totimize your Ethereum fllow Data, taking only 1h klines.
Who 1H Kline are mono
With a large number of ticks and brands available, having too data can be overwhelming. Howver, 1h Kline offrs a rud balance between coversage and landline requirements. By Focusing on the N 1h on the thick, you!
WebSockes for flow data
To simplify the process of recovery of flow data, webSockes wth your eTHREUM supplier (eg, binance). WebSockets activation bidirectional communication between your application and the supplier. It is allows you to the point updates prior to your stand (in this case a web app) to the same.
step by step
- Configure the WebSocout Connection : Create a WebSocot Connection whe Etherum superplier use the API docmentation.
- Define Kline recovery parameters : Specify texts and time intervals for the recover Klines (g 1h).
- Use webSockets incorporated streaming capacities : When new data is available, use the
OnMesageven to the exactly Kline Data.
- Filter ause data : Use a Simple algorithm (such as this one presented below) to filter the mid values and to kee 1h on the 1h.
Here are ae are a sesmple code in Javascript use Binance’s webSockes:
`JavaScript
const webSockeet = requires ('ws');
Const Wss = NewSocout.Server ({port: 8080});
// Define thicks and time intervals for it
Const Tickers = ['Eth', 'Btc'];
const interval = {h: 1};
// Function to filter unnecessary data
GETTTOPNKLINS function (WS, TICkers) {
Const kline = {};
// recover Top n kline on the tick
ws.on ('message', (data) => {
const {ticker, kline} = json.parse (data);
if (! kline [ticker]) {
kline [ticker] = [];
}
kline [ticker] .push (kline);
});
// filter middle values
Object.values (Kline) .Foreach ((Klinesarray) => {
Const Middleindex = Math.Floor (Klinesarray.length / 2);
IF (Middleindex> 0 && Middleindex
Klinesarray.Splici (Middleindex, 1);
}
});
return object.Frmentries (object.entries (kline) .map ([ticker, array]) => [ticker, array]);
}
ws.on ('error', (error) => console.error (error));
ws.on ('close', () => console.log ('webSocout connection);
ws.listen (8080, () => {
Console.log ('WebSockeet Server Listening on port 8080');
});

By following theese and using Binance webSockers, you can simplily This approach would help you stay organized and based onmarket acting, that matters for you to happy coding application!
