How does DIA fetch OKEx trade data?

DIA takes a comprehensive approach to fetching trade data from different types of exchanges, depending on whether they are DeFi or NFT exchanges.

For centralized exchanges like Coinbase, Kraken, and Binance, DIA directly collects trades from exchange databases using Rest APIs or WebSocket APIs. This allows DIA to retrieve trading data as close to the data source as possible, ensuring high precision. The frequency of data collection varies from 1 to 7 seconds, depending on the exchange.

On the other hand, for decentralized exchanges, DIA collects data from various blockchains by subscribing to swap events in liquidity pools. This approach allows DIA to retrieve trading data directly from the blockchain itself, enhancing data accuracy. Examples of decentralized exchange sources include Uniswap, curve.finance, and PancakeSwap.

When it comes to NFT marketplaces, DIA captures live trading data with a retrieval period ranging from 20 seconds to 1 minute. This covers all NFT transactions happening in real-time on DIA's integrated marketplace's smart contracts. By doing so, DIA ensures data precision from the broader NFT market, as it doesn't rely on unreliable bids and offer data. Notable NFT integrated exchange sources include Blur, X2Y2, OpenSea, and TofuNFT.

Overall, DIA's process of fetching trade data involves direct collection from exchange databases, subscription to swap events in liquidity pools, and capturing live data from integrated NFT marketplaces. This comprehensive data management strategy enables DIA to provide highly accurate and customizable price feeds.

How build oracles with OKEx data?

DIA has a systematic process for computing trade data from OKEx to build price feed oracles for different types of exchanges, such as DeFi or NFT.

For DeFi exchanges, DIA follows a two-step process. The first step involves data cleaning and outlier detection. This ensures that trades with prices significantly diverging from the market price are excluded. By applying an Interquartile Range (IR) filter, DIA removes data points and sets that fall outside an acceptable range relative to the interquartile range. This helps prevent irregularities caused by market manipulation, errors, or flash crashes.

In the second step, DIA applies price determination methodologies to calculate the final price from the remaining data points. One example is the Volume Weighted Average Price (VWAP), which considers the different volumes of trades. Trades are collected and weighted by volume, and the weighted average price is calculated.

On the other hand, building price oracles for NFT collections involves a slightly different process. Firstly, the on-chain trade data is cleansed to exclude market outliers and manipulation techniques. Secondly, a pricing methodology is applied to determine the floor price of the NFT collection.

The simplest methodology is the Floor Price, which provides the lowest sale price of an NFT collection recorded on the blockchain during a specific time window. However, this method is susceptible to manipulation. Hence, DIA offers advanced methodologies, such as the Moving Average of Floor Price, which returns the moving average of the collection's floor price. This methodology can be customized with parameters like the length of the average or the size of the floor window.

DIA also applies an interquartile range outlier detection filter and is open to discussing custom filters and methodologies for specific use cases.

Overall, DIA employs rigorous processes to ensure the accuracy and reliability of price oracles built from OKEx trade data for both DeFi and NFT exchanges. These processes involve data cleaning, outlier detection, and the application of specific pricing methodologies tailored to the characteristics of each type of exchange.
