Introduction of the YokeF Price Index

YokeF Price Index is calculated based on the pairings available and collected by YokeF from the various exchanges for a particular crypto asset. We use a variety of data sources to measure the index. At present YokeF uses 6 price components: Binance, Coinbase, CoinHe, Huobi, Okex, Bittrex.

The price quoted on YokeF calculated by taking the REALTIME price-weighted average of prices reported at each exchange through API. We use specific methods to detect malformed and anomalous data then discard them.

Price calculation weights from exchanges are publicly available at this site. All changes will be officially announced on YokeF's communication channels at least 24 hours before applying.

The average price will be equal to the weighted average of prices at the above-mentioned exchanges. The sum of Weights across all price components was 100.

YokeF Price Index = (W1P1 + W2P2 + W3P3 + W4P4 + W5P5 + W6P6) / 100

Where:

  • Index Weights (%) of various exchanges is represented by W1, W2, W3, W4, W5 and so on.
  • Last BTC/USD price ****at various exchanges is represented by P1, P2, P3, P4, P5 and so on.

**YokeF Price Index** = (W1*P1 + W2*P2 + W3*P3 + W4*P4 + W5*P5 + W6*P6)/100 == (40 * 9797 + 10 * 9792 + 10 * 9793 + 18*9789 + 12*9790 + 10*9796) / 100

= 9793.72

Outliers

YokeF uses several methods to detect outliers as part of the algorithm to ensure that only the most up-to-date and most accurate information is aggregated and displayed on the website.

Volume and price data obtained directly through the API on each of the above-listed constituent exchanges. If a constituent exchange is unresponsive (timeout), the price from that exchange won’t be used in the calculation until the timeout problem is solved.

If YokeF detects anomalous data from the price of any exchange with an increase or decrease of 25% or more, the data will be excluded when calculating the average price. When the price volatility is less than 25%, the component price will return to the YokeF Price Index.

In case one or more exchanges take the reference price to Price index, YokeF's price system will adjust in one of the following two directions:

If the pricing system is affected too much by disconnecting from the maintenance floor, YokeF will suspend the system for maintenance and adjustment.

If the price index is not affected much by disconnection from the maintenance exchange, then the price of that exchange will be excluded from calculation. The remaining exchanges still retain the division ratio as in the latest published formula. The weight of the disconnected exchange will re-divide by weighted average for the remaining exchanges.

In some cases, the connection between YokeF and international exchanges was interrupted midway resulting in the absence of candle close data. To ensure the fairness of users, YokeF will recognize tie results for these rounds and refund the amount ordered to users.

Disclaimer

YokeF takes no responsibility for the accuracy, in compliance with YokeF Terms of Service, of any volume (or other) data obtained from an exchange and used for computing the value of any YokeF Price Index. We exempt all responsibility for any reported losses resulting from calculating or publishing that index.

Balance system

When trading on YokeF, users trade with other users. We use the trading balance system to ensure fairness. For transactions with a difference in the total value of “Higher" and “Lower", we will use our system to automatically place the opposite order at other exchange (Bitmex)

For example:

10 “Higher" orders with a value of $1 per order and 8 “Lower" orders with a value of $1 per order.

Our system will automatically place 2 “Higher" sell orders with the corresponding value of $ 1 on the futures exchange (Bitmex) and the amount placed on YokeF will be guaranteed to be balanced and fair.
